The code in src/cpu/x86/mtrr/mtrr.c disables caching in a few places when
changing mtrr settings. While I can't find anything that says that's actually
required, I can believe it's necessary. With that said, other code around the
wrmsr instructions which actually modify the settings should be able to run
with caching enabled with no ill effects.
This is particularly true for two calls to printk, one in the fixed mtrr code
and one in the variable, which could result in an arbitrary amount of work
being done without caching. When changing the implementation of the cbmem
console, these two printks caused a significant regression in boot performance
on link of about 70ms which is about 10% of total firmware boot time. When the
window where the cache is disabled is minimized, both this and the new
implementation were about 30ms faster than the original boot time.
For the variable MTRRs, we now store what we want to set the MSRs to and then
write them all at once at the end of commit_var_mtrrs(). This way we don't
have some set and some not, but we still minimize the time we spend with the
caches disabled.

This is essentially a revert of commit 10bd772d. The CAR_MIGRATE
mechanism is only useful to migrate variables from a special region
(e.g. cache as RAM) into DRAM-backed CBMEM between different parts of
the romstage (it does not persist into ramstage). Since ARM devices use
SRAM for which there is no reason to become inaccessible in later parts
of the romstage, this mechanism isn't useful for them. Removing it makes
the romstage.ld script much simpler, which has the nice side-effect of
putting the BSS at the end of the memory image (so that cbfstool can
actually figure out that it doesn't need to be part of the ROM image).

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

Peppy had some issues with FUI. We decided it was time to create
peppy-specific gma.c and i915io.c files. Using yabel and the i915tool,
we generated a replay attack, then interpolated against the slippy
i915io.c to get something working.
Also, in preparation for moving code out of the mainboard gma.c to
generic driver code, we got rid of some hardcodes in the mainboard
gma.c that have no business being there. The worst were the
computation of gmch_[m,n] and it turns out that we had some
long-standing bugs related to confusion about 'bpp'. I've killed the
word bpp everywhere I could because there are at least 3 things that
correspond to bpp. We now have framebuffer, pipe, and panel bpp. The
names are long because I want to avoid all the mistakes we've all been
making in the last year :-) Sadly, that means a lot of changes not just
peppy-related, but they are simple and in a good cause.
The test pattern generation is driven by a global variable in
mainboard/peppy/gma.c. I've found in the past that it's very useful
to have a function like this available, as one can activate it while
using a jtag debugger: halt at the right place in ramstage, set the
variable to 1, continue. It's not enough code to worry about always
including.
The last hard-codes for M and N registers are gone, and the function
to set from generic intel_dp.c code works. To avoid screen trash on a
dev mode boot, which we liked but nobody else did :-), we now take the
time to put a pleasing background color that sort of doubles as a
power LED.
Rough timing is ramstage start is at 2.2, and dev setup is done at
3.3. These new platforms are depressingly slow to boot. Rom init alone
is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash
prompt. These CPUs are at least 10x faster and take much longer to get going.
Future work, once we get this through, is to move more functions to the
intel driver, and combine the mainboard i915io.c into the mainboard gma.c.
That separation only existed because i915io.c was generated by a tool, and it
had lots of ugliness. Most ugliness is gone.

The UART / serial console is put in retention state by kernel during suspend /

Sending values to the padret_uart_opt inside PMU may release UART, but that may
also cause unexpected output when kernel is back. However, it's still very
helpful when we are debugging suspend/resume inside Coreboot.
To get UART message on resume, call wakeup_enable_uart() in boot block or

This patch cleans out a lot of unused variables in the
ARM Kconfig files and introduces CONFIG_RAMSTAGE_BASE
which is similar to CONFIG_RAMBASE on x86.
This gets rid of the hard coded assumption that on ARM
coreboot is always executed at the lowest DRAM address.
But in fact, this might not be true because we might want
coreboot to live at the end of RAM, or in SRAM

All this samsung_get_base_address_of_device_with_a_really_long_name()
boilerplate makes my eyes bleed... I think there are so much cleaner
ways to do this. Unfortunately changing this ends up touching nearly
every Exynos5 file, but I hope you agree that it's worth it (and the
sooner we get it over with, the better... I can't bring myself to make
another device fit into that ugly scheme).
This also removes the redundant EXYNOS5 base address definitions from
the 5420 directory when there are EXYNOS5420 ones, to avoid complete
confusion. The new scheme tries to use EXYNOS5 for base addresses and
exynos5 for types that are common between the two processors, and
EXYNOS5420/exynos5420 for things that have changes (although I probably
didn't catch all differences).

for exynos5420, pit, and kirby. Specifically:
- CONCONTROL.empty is read-only, so don't try to set it and also
get rid of the unneeded DMC_CONCONTROL_EMPTY_ENABLE #define.
- MEMBASECONFIG* overlaps members of the mem_timings struct and
are mainboard-dependent anyway, so get rid of 'em.
- DMC_MEMCONTROL_TP_DISABLE corresponds to a reserved bit. It may
have been deprecated.
- Same with TIMING* #defines.
- Clarify DDR_MODE_* usage and use mem->mem_type when appropriate.

This changes the number of chip selects that we configure from 2 to 1.
On current setups with (x16 memory 4Gbit chips) that means that we're
at 2GByte.
Technically we should add a second setting in the ares_ddr3_timings
and select between the two of the based on board strappings. That
would make the CONFIG_RUN_TIME_BANK_NUMBER work properly. I've
changed the ddr3_mem_ctrl_init() so it should handle that, but I'm not
actually doing the board strapping read right now.
This change means that accesses to 0xA0000000 - 0xFFFFFFFF on 2G
systems will no longer put the system in a messed up state (leading to
a hang). It also prevents some of the weird boot behavior that we've
seen that comes and goes depending on U-Boot alignment. See

This patch intends to remove all code which enables hardware read
leveling. We need to disable h/w read leveling because new ASV table
is merged in kernel (which is based on the new characterization
condition) and new characterization environment has h/w read leveling
disabled, so we should also disable this. Also, disabling h/w read
leveling improves the MIF LVcc value (LVcc value is the value at which
DDR will fail to work properly), improve LVcc means we have enough
voltage margin for MIF. When h/w leveling is enabled, we have almost
zero volatge margin.

As per hardware recommendation, CKE PAD retention release must
happen just before gate leveling enable and only in case of resume.
Hence, this patch moves pad retention release from dmc_common.c to
dmc_init_ddr3_exynos5420.c. In addition to this we are providing
125 (+3 extra being safe) times auto refresh to DRAM by sending
REFA direct command. This is required because when CKE PAD retention
release happens, self refresh mode of DDR3 is disabled.
Hence, auto refresh 125 times.
This is ported from https://gerrit.chromium.org/gerrit/#/c/65573
Note: Since WAKEUP_DIRECT does not go thru memory init, it should be
safe to move CKE PAD retention out of bootblock.c.

Apparently the IROM doesn't like data caches... the recently added
dcache-in-bootblock makes A-A booting fail, and flushes/invalidations
alone don't seem to fix it. It's pretty fast anyway, so we just disable
the cache again for the duration of the IROM call.
Also removes a superfluous invalidation line from the bootblock code...
dcache_mmu_enable/disable already take care of that.

snow and pit: turn on FET4 (for SD card) at bootup
Explictly enable FET4 on Snow and Pit.
Historically we haven't needed to do this because:
* On snow there's a bypass around FET4 which effectively eliminates
it. Even if we don't turn on FET4 the SD card is still powered.
Turning on FET4 doesn't hurt though and is technically correct.
* On pit the EC turns on FET4 on cold bootup.
On pit we run into a problem if the kernel turns off FET4 like in
<https://gerrit.chromium.org/gerrit/#/c/65332/> and then we get a
software reset or warm reset. In this case the EC won't know to turn
it back on.

Provide functionality to create dynamic classes based on program name and
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class. Also, compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.
One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.

We were running this loop 100 times with 5 ms delays. Change it
to run 500 times with 1 ms delays, which gives us the same
overall timeout but lets us bail out a bit sooner -- in practice,
at most, 4 ms sooner but every bit counts. Note, however, that
the tighter timing does reduce opportunities for threading. There
is a non-obvious set of tradeoffs on timeouts.

This patch enhances the armv7 exception handlers in Coreboot and
libpayload to show the correct SP and LR registers from the aborted

access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
