Currently, the exception handling code on ARM turns on alignment checks as an
easy way to generate an exception for testing purposes. It was leaving it on
which disabled unaligned accesses for other, unlreated code running later.
This change adjusts the code so the original value of the alignment bit is
restored after the test exception.

The members data structures in dmc.h are intended to have a particular size.
Rather than assume that particular types are the right size, we should use
types that are guaranteed to be the right size. Also, since the registers are
at particular offsets as well, the structures should be packed.

This updates the low-level I2C code to handle the new high-speed
HSI2C/USI inteface. It also outputs a bit more error information
when things go wrong. Also adds some more error prints. Timeouts
really need to be noted.
In hsi2c_wait_for_irq, order the delay so that we do an initial
sleep first to avoid an early-test that was kicking us out of the
test too soon. We got to the test before the hardware was ready
for us. Finally, test clearing the interrupt status register every time
we wait for it on the write. Works.

The 5420 clock code still had a data structure in it for the 5250 clock
registers which was used by some of the clock functions. That caused some
clocks to be configured incorrectly, specifically the i2c clock which was
running at about 80KHz instead of about 600KHz as configured by U-Boot.
Also, the registers and bit positions used to set up the SPI bus were not
consistent with U-Boot, and if the bus clock rate were set to 50MHz, a rate
which has historically worked on snow, loading would fail. With these fixes
the clock rate can be set to 50MHz and the device boots as much as is
expected. I haven't yet measured the actual frequency of the bus to verify
that it's now being calculated correctly.

The pinmux code for the exynos5250 was all bundled into a single, large
function which contained a switch statement that would set up the pins for
different peripherals within the SOC. There was also a "flags" parameter, the
meaning of which, if any, depended on which peripheral was being set up.
There are several problems with that approach. First, the code is inefficient
in both time and space. The caller knows which peripheral it wants to set up,
but that information is encoded in a constant which has to be unpacked within
the function before any action can be taken. If there were a function per
peripheral, that information would be implicit. Also, the compiler and linker
are forced to include the entire function with all its cases even if most of
them are never called. If each peripheral was a function, the unused ones
could be garbage collected.
Second, it would be possible to try to set up a peripheral which that function
doesn't know about, so there has to be additional error checking/handling. If
each peripheral had a function, the fact that there was a function to call at
all would imply that the call would be understood.
Third, the flags parameter is fairly opaque, usually doesn't do anything, and
sometimes has to have multiple values embedded in it. By having separate
functions, you can have only the parameters you actually want, give them
names that make sense, and pass in values directly.
Fourth, having one giant function pretends to be a generic, portable API, but
in reality, the only way it's useful is to call it with constants which are
specific to a particular implementation of that API. It's highly unlikely that
a bit of code will need to set up a peripheral but have no idea what that
peripheral actually is.
Call sights for the prior pinmux API have been updated. Also, pinmux
initialization within the i2c driver was moved to be in the board setup code
where it really probably belongs. The function block that implements the I2C
controller may be shared between multiple SOCs (and in fact is), and those
SOCs may have different pinmuxes (which they do).
Other places this same sort of change can be made are the pinmux code for the
5420, and the clock configuration code for both the 5250 and the 5420.

The memset and memcpy functions are assembled as ARM code, likely because
that's the default of the assembler. Without special annotation, the assembler
and linker don't know that those symbols are functions which need special
handling so that ARM/thumb issues are handled properly. This change adds that
annotation which gets those functions working in Coreboot which is compiled as
thumb. Libpayload and depthcharge are compiled as ARM so they don't *need* the
annotation since it just works out in ARM mode, but it's the safe thing to do
in case we change that in the future.
We should explicitly select ARM vs. thumb when assembling assembly files to be
consistent across builds and toolchains.

It might be that you want an early console in romstage before RAM is up, but
you can't or don't want to support the console all the way back in the
bootblock. By making the console in those two different environments
configurable seperately that becomes possible.
On the 5250 console output as early as the bootblock works, but on the 5420 it
only starts working in the ROM stage after clocks have been initialized.

Now that we are executing VbInit() in coreboot we can end up
in a situation where the recovery reason is consumed during
VbInit (end of romstage) and then the EC is rebooted to RO
during ramstage EC init, thereby losing the recovery reason.
Two possiblities are to remove the EC check+reboot from ramstage
and let it happen in depthcharge. This however means that the
system has to boot all the way into depthcharge and then reboot
the EC and the system again.
Instead if we do a check in romstage before VbInit() is called
then we can reboot the EC into RO early and avoid booting all
the way to depthcharge first.
This change adds a ramstage version the EC init function and
calls it from the shared romstage code immediately after the
PCH decode windows are setup.

If we clear the framebuffer and then flush it back to memory using cache
operations, the writes are going to be full cachelines at a time. If we make
it uncacheable first, the writes will be serialized writes of whatever sized
chunks memset uses, probably 4 bytes or less.

At one time it seemed to be necessary to disable and then re-enable the MMU
when setting the framebuffer to be uncache-able due to bugs in the MMU

When modifying the page tables, use writel to ensure the writes happen, flush
the page tables themselves to ensure they're visible to the MMU if it doesn't
look at the caches, and invalidate the right TLB entries.
The first two changes are probably safer but may not be strictly necessary.
The third change is necessary because we were invalidating the TLB using i
which was in megabytes but using an instruction that expects an address in
bytes.
One symptom of this problem was that the framebuffer, which was supposed to be
marked uncacheable, was only being partially updated since some of the updates
were still in the cache. With this change the graphics show up correctly.

The code that allocated space for the framebuffer was adding space for a
vestigial color map which was never used. It was also passing around a
structure which was used to calculate a single value which was already known
when that structure was put together. Eliminate the extra space, and pass the
single value instead of the structure.

The page tables need to be aligned to a 16KB boundary and are 16KB in size.
The CBMEM allocator only guarantees 512 byte alignment, so to make sure
things are where they're supposed to be, the code was allocating extra space
and then adjusting the pointer upwards. Unfortunately, it was adding the size
of the table to the pointer first, then aligning it. Since it allocated twice
the space of the table, this had the effect of moving past the first table
size region of bytes, and then aligning upwards, pushing the end of the table
out of the space allocated for it.
You can get away with this if you push things you don't care about off the
end, and it happened to be the case that we were allocating a color map we
weren't using at the start of the next part of cbmem.

Add three functions to edid.c:
void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr)
takes an edid and uintptr_t, and fills in a static lb_framebuffer struct
as well as setting the static vbe_valid to 1 unless some problem
is found in the edid. The intent here is that this could be called from
the native graphics setup code on both ARM and x86.
int vbe_mode_info_valid(void)
returns value of the static vbe_valid.
void fill_lb_framebuffer(struct lb_framebuffer *framebuffer)
copies the static edid_fb to lb_framebuffer.
There is now a common vbe.h in src/include, removed the two special ones.
In general, graphics in coreboot is a mess, but graphics is always a
mess. We don't have a clean way to try two different ways to turn on
a device and use the one that works. One battle at a time. Overall,
things are much better.
The best part: this code would also work for ARM, which also uses EDID.

This code is the initial version of FUI for haswell and wtm2.
The code is simplified from before in many ways. I've gotten rid of
the opcode table, because it obscured meaning and I don't think it is
needed any more. Register sets, mainly used for reset, are just lines
of code -- not many of them. There are a bunch of not-yet-documented
registers here; the VBIOS seemed to think they were necessary and
testing shows they seem to be right.
As a bit of added paranoia, we always include the VBIOS code as our
emergency recovery path. You have to run it now anyways, so this is no
regression from our current situation; and, if all goes well, in a
week (or so), you'll never have to run it again, but like the Force
and nose hair, it will be with you always.
The code can return in three ways. The first, best way is success:
panel is up and the VBIOS need not run. The second mode is that we
tried to light up the panel but could not, for some reason, but will
return with the panel partly up. In this case, it's ok not to power
cycle the panel. The third, worst case, which will NEVER happen, ha
ha, is that we have to turn the panel off and wait the required 600ms
for it to cycle. Life sucks sometimes. This failure mode is in the
'hang on we're going to fix it' category now that we have ramstage in
RW.
The Big Goal here is to create something other coreboot ports can use
as well. The guys doing the x60 report that the link FUI works,
without too many mods, on that chipset, so it seems Intel is keeping
things from changing too much over time.
Also, again, please note: this and the next 3 versions will ALWAYS fail.
The goal is to verify the correctness of the recovery path.
The bizarre tab-space formatting in drm_dp_helper.h is from the original,

The PnP's logical device activation normally resides at 0x30. This might
have been overlooked as 0x29 looks very close to 0x30 in human eyes.

The enumeration method tried to evaluate an one-byte OperationRegion
instead of a field in this OperationRegion, which resulted in an
AE_TYPE error at runtime.
Indexing the OperationRegion with a single field fixes this error.

The W83627DHG has some power managements bits to power down individual
logical devices. These are called `* Power Down`. Counterintuitively and
in contrast to `Immediate Power Down` (bit to power down the whole chip),
these bits are set when the respective logical device is powered.
Unfortunately, our ACPI code set them wrong which led to disabled
devices after a S3 suspend/resume. Adding an option how to set the PM
bits and setting them to zero for the W83627DHG, corrects it.
Tested with kontron/ktqm77.

of 4. The src/northbridge/via/vx900/Kconfig also defines
MAX_PIRQ_LINKS with a default of 8 and it ends up giving us
a value of 8 for non-VIA platforms.

The .dependencies rule did not use the CPPFLAGS variable which led
to funny behavior: a spurious termination message the first time
(after checkout/make distclean) one executes make. Afterwards the
(wrongly) empty .dependencies file hides the problem and the binary
is created anyway.
$ make
cbmem.c:37:34: fatal error: boot/coreboot_tables.h: No such file or directory
compilation terminated.
cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86 -c -o cbmem.o cbmem.c
cc cbmem.o -o cbmem
$ make
make: Nothing to be done for `all'.
$ make clean
rm -f cbmem *.o *~
$ make
cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86 -c -o cbmem.o cbmem.c

I fixed that by adding the CPPFLAGS variable to the .dependencies recipe, just
like Stefan Reinauer did in Chromium (Ia9d2e10a3ef122f30d681d16c2291eb108ead835),
hence the split sign-off for this tiny change. :)
