Please, don't just add random directories for a single file because
it seems convenient. There already is a chromeos directory, that should
be used.

Stefan Reinauer b8ad224468 cbmem: replace pointer type by uint64_t
Since coreboot is compiled into 32bit code, and userspace
might be 32 or 64bit, putting a pointer into the coreboot
table is not viable. Instead, use a uint64_t, which is always
big enough for a pointer, even if we decide to move to a 64bit
coreboot at some point.

David Hendricks ea22796eda armv7: Add temporary build script for CrOS devs
This build script will:
- Build coreboot.rom
- Download BL1, extract and place it if necessary
- Do a partial flash via Servo, using some flashrom trickery to
  make the process fast.

This probably should not be submitted, unless the intention is to
back it out eventually.

Credit goes to Hung-Te for writing the original version.

CPU 0 takes lapic from 0x10 to 0x17 and CPU 1 takes from 0x20 to 0x27.
So the first core's lapic is 0x10 rather than 0x20.

David Hendricks 858b65028e cleanup some exynos5250 uart code
This just cleans out some unused headers and tidies up the early
serial code.

TODO: Clean-up or replace FDT code, make "base_port" easier to
configure.

A bit of cleanup based on earlier patches.

David Hendricks 6a503b6a0f make early serial console support more generic
This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.

This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.

The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.

uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

David Hendricks 10c90d3126 update CFLAGS for armv7
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.

1. Add an intermediate Makefile rule for dd'ing BL1 into the

   for the bd82x6x southbridge.
2. Add a Kconfig variable, BOOTBLOCK_OFFSET, which will be used to
   pass the bootblock offset into cbfstool.
