This patch renames arm_tf.c and arm_tf.h to bl31.c and bl31.h,
respectively. That name is closer to the terminology used in most
functions related to Trusted Firmware, and it removes the annoying
auto-completion clash between arm64/arm_tf.c and arm64/armv8.

This patch changes the Rockchip SPI and I2C drivers to use the new
buffer_from_fifo32()/buffer_to_fifo32_prefix() helpers when accessing
their FIFOs (mostly just to demonstrate that/how the helpers work).

To make explicit when vboot2 error codes should be returned,
use the new vb2_error_t type on all functions which return
VB2_ERROR_* constants.
Additionally, add required vboot submodule commit id e6700f4c:

This multiplication is of the form u64 = u32 * u32. Despite being stored
in a 64 bit variable, the intermediate value is still calculated using
32 bit math, which could possibly overflow. Cast one of the variables to
a u64 to ensure it uses 64 bit math instead to avoid this.

Implicit fall throughs are a perpetual source of bugs and Coverity Scan
issues, so let's squash them once and for all. GCC can flag implicit fall
throughs using the -Wimplicit-fallthrough warning, and this should
ensure no more enter the code base. However, many fall throughs are
intentional, and we can use the following comment style to have GCC
suppress the warning.
switch (x) {
case 1:
y += 1;
/* fall through */
case 2:
y += 2;
/* fall through - but this time with an explanation */
default:
y += 3;
}
This patch adds comments for all remaining intentional fall throughs,
and tweaks some existing fall through comments to fit the syntax that
GCC expects.

Judging from the state machine on page 281 of the Rockchip RK3288
Technical Reference Manual (Rev 1.0 - Jun 2015), the fall through
from the INIT_MEM -> CONF states is intentional, since that is the
only way to get to the ACCESS state. Add a comment to explain this.

When we added CONFIG_VBOOT_MIGRATE_WORKING_DATA, the idea was that on
some Arm platforms the original working data buffer was in SRAM, which
stays accessbile for the whole runtime of the system. There is no reason
to migrate it into CBMEM on those platforms because ramstage and the
payload could continue to access it in SRAM.
Now that we've had a couple of months of experience with this option, we
found that most of our Arm platforms have some issue that requires
migrating anyway, because BL31 often claims SRAM for itself and makes it
inaccessible to the payload. On the remaining platforms, accessing SRAM
from the payload is possible but still an issue, because libpayload
doesn't have enough memory layout information to set up proper page
tables for it, so we're accessing it uncached and at risk of alignment
errors.
Rather than having to figure out how to map the right SRAM range for
every platform in the payload, let's just get rid of the option.
memcpy()ing 12KB isn't worth this much hassle.

This patch fixes up all code that would throw a -Wtype-limits warning.
This sometimes involves eliminating unnecessary checks, adding a few odd
but harmless casts or just pragma'ing out the warning for a whole file
-- I tried to find the path of least resistance. I think the overall
benefit of the warning outweighs the occasional weirdness.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow
backwards. Fix that. Now, CONSOLE_SERIAL depends on DRIVERS_UART,
because it's using its interface. The individual UART drivers
select DRIVERS_UART, because they implement the interface and
depend on the common UART code.
Some guards had to be fixed (using CONSOLE_SERIAL now instead of
DRIVERS_UART). Some other guards that were only about compilation
of units were removed. We want to build test as much as possible,

RK3288 has always been notoriously low on SRAM, to the point where its
boards have less than 100 bytes left in both their bootblock/verstage
sections. This becomes a problem every time we try to add a tiny amount
of code to common coreboot interfaces that are included in them.
This patch manages to add another KB to each, one from the CBMEM console
(which now might get cut off a bit, but that's life) and one by moving
the TTB_SUBTABLES to PMUSRAM. PMUSRAM is a weird world where write
accesses must always be exactly 4 bytes long or they hang the CPU, so we
mostly ignore it... but thankfully, page table entries are exactly 4
bytes long and that's the only thing we write to this region, so it
works out in this case.

This patch enables the new bootblock compression feature on RK3399,
which requires moving MMU initialization into the decompressor stage and
linking the decompressor (rather than the bootblock) into the entry
point jumped to by the masked ROM.
RK3399's masked ROM seems to be using a bitbang SPI driver to load us
(very long pauses between clocking in each byte), with an effective data
rate of about 1Mbit. Bootblock loading time (as measured on a SPI
analyzer) is reduced by almost 100ms (about a third), while the
decompression time is trivial (under 1ms).

Sometimes when bringing up a new board it can take a while until you
have all the peripheral drivers ready. For those cases it is nice to be
able to bitbang certain protocols so that you can already get further in
the boot flow while those drivers are still being worked on. We already
have this support for I2C, but it would be nice to have something for
SPI as well, since without SPI you're not going to boot very far.
This patch adds a couple of helper functions that platforms can use to
implement bit-banging SPI with minimal effort. It also adds a proof of
concept implementation using the RK3399.
