Our reference toolchain uses -mabi=aapcs whereas we started
forcing -mabi=aapcs-linux. Drop this to prevent ABI incompatibility.
Also drop -fno-common since that's set in the top level Makefile.inc

There was a misuse of bool that would cause the dcache policy to not be
set up correctly, but instead present options "y" and "n" in the Kconfig
menu.
Also, TINY_BOOTBLOCK was removed a while ago, everything is
TINY_BOOTBLOCK now. Hence remove the option.

This updates $CFLAGS used for armv7. Most of them were just added
to be consistent with what u-boot does. The important ones here
are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions).
I removed the hard float support because it got errors and
coreboot should never use floats anyway. We're still having trouble
with enums but I want to see how far it gets with this patch.
Also, put the flags in a form that makes diffs easier to read. It's
almost impossible otherwise.
Finally, move some flags to the architecture Makefile, and
rely on the fact that some are set for all architectures.

As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.

The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.
These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.
With ramstage.a gone, we can drop this special class, too.

ramstage.a has two issues:
1. duplicate source filenames don't survive the ar(1)
treatment properly (so files aren't considered)
2. ld doesn't resolve symbols if it isn't forced to, in
particular no overrides of weak symbols
Downside: The resulting binaries get slightly larger.
Link time optimizations should fix that, as would tighter
rules in the build system (to not compile unused code in
the first place).

The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.
In order to restore this pointer it needs to be available
at resume time. The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself. So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.
A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.
The cpu_index variable had to be renamed due to a conflict
when cpu/cpu.h is added for the smm_setup_structures()
prototype.

This addition is in support of future multicore support in

cores are brought up, NOT its APIC id -- is passed into the
secondary start. We modify the function to specify regparm(0).
We also take this opportunity to do some cleanup:
indexes become unsigned ints, not unsigned longs, for example.
Build and boot on a multicore system, with pcserial enabled.
Capture the output. Observe that the messages
Initializing CPU #0
Initializing CPU #1
Initializing CPU #2
Initializing CPU #3

Double equal sign like "test a == b" works. It really does, except NetBSD.
But I haven't found any clue in the manual for the command test about "==".

coreboot uses about 2K of stack on the BSP, and about 1K of stack on the
APs. No reason to use an overdimensonal stack of 32k per core/thread.

At least when CONFIG_CHROMEOS is turned on, it's possible for
CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid
information to put into the framebuffer coreboot table. That means that what's
put in there is junk, probably all zeroes from the uninitialized global
variable the mode information is stored in (mode_info).
When a payload uses libpayload and turns on the coreboot framebuffer console,
that console will attempt to scroll at some point and decrease the cursor's y
coordinate until it is less than the number of rows claimed by the console.
The number of rows is computed by taking the vertical resolution of the
framebuffer and dividing it by the height of the font. Because the mode
information was all zeroes, the coreboot table info is all zeroes, and that
means that the number of rows the console claims is zero. You can't get the
unsigned y coordinate of the cursor to be less than zero, so libpayload gets
stuck in an infinite loop.
The solution this change implements is to add a new function,
vbe_mode_info_valid, which simply returns whether or not mode_info has anything
in it. If not, the framebuffer coreboot table is not created, and libpayload
doesn't get stuck.

And move the pre-hardwaremain post code to 0x79
so it comes before hardwaremain at 0x80.
Emit these codes from ACPI OS resume vector as well
as the finalize step in bd82x6x southbridge.
