It became necessary to decode base64 data retrieved from VPD and
convert it into binary for inclusion in the device tree.
The patch introduces the decoder function based on the description
found in http://en.wikipedia.org/wiki/Base64.
An open source implementation from http://base64.sourceforge.net was
considered, in the end the only thing borrowed from it is the table to
translate base64 ascii characters into numbers in 0..63 range.

BUG=chromium:450169
TEST=created a test harness generating random contents of random size
(in 8 to 32766 bytes range), then converting the contents into
base64 using the Linux utility, and then converting it back to
binary using this function and comparing the results.
It succeeded 1700 iterations before it was stopped.

This patch removes quite a bit of code duplication between cpu_to_le32()
and clrsetbits_le32() style macros on the different architectures. This
also syncs those macros back up to the new write32(a, v) style IO
accessor macros that are now used on ARM and ARM64.

TEST=Compiled Cosmos, Daisy, Blaze, Falco, Pinky, Pit, Rambi, Ryu,

unfortunately something about the new macro notation makes the compiler
evaluate it more efficiently (not recalculating the address between the
read and the write), so this was of limited value.

This patch introduces a new option (CONFIG_MULTIPLE_CBFS_INSTANCES) to
allow multiple CBFS instances in the bootrom.
When the new option is enabled, the code running on the target
controls which CBFS instance is used. Since all other then header CBFS
structures use relative addressing, the only value which needs
explicit setting is the offset of the CBFS header in the bootrom.
This patch adds a facility to set the CBFS header offset. The offset
value of zero means default. i.e. the CBFS initialization code still
discovers the offset through the value saved at the top of the ROM.

UART, which has the same register layout, but mapped to a bus of a

A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.
TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
others don't, for seemingly unrelated reasons.

This adds a 10us delay in between (re-)configuring and reading
GPIOs in gpio_base2_value() to give the values stored some time

checkstack() runs at the end of ramstage to warn about stack overflows,
and it assumes that CONFIG_STACK_SIZE is always the size of the stack to
check. This is only true for systems that bring up multiprocessing in
ramstage and assign a separate stack for each core, like x86 and ARM64.
Other architectures like ARM and MIPS (for now) don't touch secondary
CPUs at all and currently don't look like they'll ever need to, so they
generally stay on the same (SRAM-based) stack they have been on since
their bootblock.
This patch tries to model that difference by making these architectures
explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to
assume the whole (_estack - _stack) area in checkstack() instead. Also
adds a BUG() to the stack overflow check, since that is currently just
as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM
HALTED" output) but a little more easy to spot. Such a serious failure
should not drown out in all the normal random pieces of lower case boot
spam (also, I was intending to eventually have a look at assert() and
BUG() to hopefully make them a little more useful/noticeable if I ever
find the time for it).

Now that we have timestamps in pre-RAM stages, let's actually make use
of them. This patch adds several timestamps to both the bootblock and
especially the verstage to allow more fine-grained boot time tracking.
Some of the introduced timestamps can appear more than once per boot.
This doesn't seem to be a problem for both coreboot and the cbmem
utility, and the context makes it clear which operation was timestamped
at what point.
Also simplifies cbmem's timestamp printing routine a bit, fixing a
display bug when a timestamp had a section of exactly ",000," in it
(e.g. 1,000,185).

BUG=None
TEST=Booted Pinky, Blaze and Falco, confirmed that all timestamps show

We have known for a while that the old x86 model of calling init_timer()
in ramstage doesn't make sense on other archs (and is questionable in
general), and finally removed it with CL:219719. However, now timer
initialization is completely buried in the platform code, and it's hard
to ensure it is done in time to set up timestamps. For three out of four
non-x86 SoC vendors we have brought up for now, the timers need some
kind of SoC-specific initialization.
This patch reintroduces init_timer() as a weak function that can be
overridden by platform code. The call in ramstage is restricted to x86
(and should probably eventually be removed from there as well), and
other archs should call them at the earliest reasonable point in their
bootblock. (Only changing arm for now since arm64 and mips bootblocks
are still in very early state and should sync up to features in arm once
their requirements are better understood.) This allows us to move
timestamp_init() into arch code, so that we can rely on timestamps
being available at a well-defined point and initialize our base value as
early as possible. (Platforms who know that their timers start at zero
can still safely call timestamp_init(0) again from platform code.)

Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.
Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).
Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

This patch makes a few cosmetic changes:
- Rename tristate_gpios.c to gpio.c since it will soon be used for
binary GPIOs as well.
- Rename gpio_get_tristates() to gpio_base3_value() - The binary
version will be called gpio_base2_value().
- Updates call sites.
- Change the variable name "id" to something more generic.

The function to read board IDs from tristate GPIOs currently supports
two output modes: a normal base-3 integer, or a custom format where
every two bits represent one tristate pin. Each board decides which
representation to use on its own, which is inconsistent and provides
another possible gotcha to trip over when reading unfamiliar code.
The two-bits-per-pin format creates the additional problem that a
complete list of IDs (such as some boards use to build board-ID tables)
necessarily has "holes" in them (since 0b11 does not correspond to a
possible pin state), which makes them extremely tricky to write, read
and expand. It's also very unintuitive in my opinion, although it was
intended to make it easier to read individual pin states from a hex
representation.
This patch switches all boards over to base-3 and removes the other
format to improve consistency. The tristate reading function will just
print the pin states as they are read to make it easier to debug them,
and we add a new BASE3() macro that can generate ternary numbers from
pin states. Also change the order of all static initializers of board ID
pin lists to write the most significant bit first, hoping that this can
help clear up confusion about the endianness of the pins.

We've had gpiolib.h which defines a few common GPIO access functions for
a while, but it wasn't really complete. This patch adds the missing
gpio_output() function, and also renames the unwieldy
gpio_get_in_value() and gpio_set_out_value() to the much easier to
handle gpio_get() and gpio_set(). The header is renamed to the simpler
gpio.h while we're at it (there was never really anything "lib" about
it, and it was presumably just chosen due to the IPQ806x include/
conflict problem that is now resolved).
It also moves the definition of gpio_t into SoC-specific code, so that
different implementations are free to encode their platform-specific
GPIO parameters in those 4 bytes in the most convenient way (such as the
rk3288 with a bitfield struct). Every SoC intending to use this common
API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most
4 bytes in length. Files accessing the API only need to include <gpio.h>
which may pull in additional things (like a gpio_t creation macro) from
<soc/gpio.h> on its own.
For now the API is still only used on non-x86 SoCs. Whether it makes
sense to expand it to x86 as well should be separately evaluated at a
later point (by someone who understands those systems better). Also,
Exynos retains its old, incompatible GPIO API even though it would be a
prime candidate, because it's currently just not worth the effort.

about cbmem being available for find() or add() operations. However,
the cbmem area was never fully recovered until entering the state
machine: BS_ON_ENTRY into BS_PRE_DEVICE. Correct this assumption
by explicitly calling cbmem_initialize() in the EARLY_CBMEM_INIT
case.
This, however, doesn't fix timestamp_init() showing an error about

This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.
The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).
BUG=None

The functions related to caching ramstage were in cbfs.h.
Now that the loading code is separate move those declarations
to the common program_loading.h.

Secure monitor runs at EL3 and is responsible for jumping to the payload at
specified EL and also to manage features like PSCI.
Adding basic implementation of secure monitor as a rmodule. Currently, it just
jumps to the the payload at current EL. Support for switching el and PSCI will
be added as separate patches.

Two weak functions were added so that architecture specific operations
on each segment of payload or stage can be performed.
Each architecture must define its own operations, otherwise the
behavior will default to do-nothing functions.
This patch has been updated by to fit more in line with
how program loading is currently being done. The API is the
same as the original, but all call sites to stages/payloads
have been updated. This is known to break any archs that use
rmodule loading that needs cache maintenance. That will be fixed
in a forthcoming patch. Also, the vboot paths are left as is
for easier upstreaming of the rest of the vboot patches.

Coreboot generic CBFS media API does not support
multiple media access instances, but it should.
With this fix the CBFS context (memory cache for
SPI accesses) is shared among all open media access
streams. A better memory management scheme might be
required, but for now this fix allows to support
booting deptcharge and accessing VPD through two
independent CBFS media streams.

TEST=no exception is thrown when the second stream
is opened
