This fixes the ACPI interrupt storm on Parrot that happens when
closing the lid or entering suspend by lid close (seen in
/sys/firmware/acpi/interrupts/gpe1F). This patch inverts the interrupt
trigger level every time the interrupt is received so that it doesn't fire
until the next state change. http://askubuntu.com/questions/310196
is a good example of what this is trying to solve.

nyan: Add a "special-class" for aggregating BCT files into bct.cfg.
The config file which cbootimage processes to create a BCT could come from
multiple different files, individually selected based on config options,
and/or split up into different files for organizational purposes. This change
adds a special-class which collects those files and concatenates them all
together in a bct.cfg which can be processed more easily by other parts of the
build.
While the BCT files themselves are potentially very board specific, for
instance ones that hold memory timing information, this bit of code which
collects them is not. It has to be in each board file instead of alongside the
CPU, however, to ensure that the special class is set up before another
Makefile tries to use it. If we end up with lots of Tegra based boards which
duplicate this code over and over, we might want to revisit how this works.

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.

"In a freestanding environment (in which C program execution may take
place without any benefit of an operating system), the name and type of

Clang complains about these being missing as Clang is somewhat more

All this samsung_get_base_address_of_device_with_a_really_long_name()

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).

A large portion of documented registers have been initialized using macros. Only a few
undocumented registers are left out. i915io.c looks lot more cleaner by removing redundant
calls. However, some more work is required to correctly identify which calls are not required.
All the io_writes are replaced by gtt_writes.

This patch renames the x86 way of doing things to
explicitly mention CMOS (which is not available on
our ARM platforms) and adds an implementation to
get VBNV through the Chrome EC. We might want to
refine this further in the future to allow VBNV
in the EC even on x86 platforms. Will be fixed when
that appears. Also, not all ARM platforms running
ChromeOS might use the Google EC in the future, in
which case this code will need additional work.

This patch adds a mechanism to set aside a region of cache-coherent
(i.e. usually uncached) virtual memory, which can be used to communicate
with DMA devices without automatic cache snooping (common on ARM)
without the need of explicit flush/invalidation instructions in the
driver code.
This works by setting aside said region in the (board-specific) page
table setup, as exemplary done in this patch for the Snow and Pit
boards. It uses a new mechanism for adding board-specific Coreboot table
entries to describe this region in an entry with the LB_DMA tag.
Libpayload's memory allocator is enhanced to be able to operate on
distinct types/regions of memory. It provides dma_malloc() and
dma_memalign() functions for use in drivers, which by default just
operate on the same heap as their traditional counterparts. However, if
the Coreboot table parsing code finds a CB_DMA section, further requests
through the dma_xxx() functions will return memory from the region
described therein instead.

This cleans up a few minor things (mostly #defines) of the memory code
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
<http://crosbug.com/p/20577>.

This patch moves around some of the existing Exynos5 USB 2.0 PHY code
to make it cleaner in preparation of the 3.0 PHYs. It moves the VBUS
GPIOs (which are completely board-specific) into the mainboard code and
makes sure to only initialize PHYs on the boards that actually need
them. It also removes the USB 3.0 PLL hack that was needed on Snow from
the Pit and Kirby boards (which do not have that PLL anymore).

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.

ramstage (mainboard_init) to prevent it from interfering with the IROM
during SDMMC boot.

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.
