Ipq8064 SBLs initialize the hardware to prepare it to run an arbitrary
user provided bootloader. The only bootloader requirements imposed by
the SBLs are that it is concatenated with the SBL chunks in the
bootprm AND it uses MBN encapsulation (mostly to specify the size and
load address).
This patch adds configuration options to specify the location of the
SBL blobs and to require MBN encapsulation of the bootblock.

This patch switches every last part of Coreboot on ARM over to Thumb
mode: libpayload, the internal libgcc, and assorted assembly files. In
combination with the respective depthcharge patch, this will switch to
Thumb mode right after the entry point of the bootblock and not switch
back to ARM until the final assembly stub that jumps to the kernel.
The required changes to make this work include some new headers and
Makefile flags to handle assembly files (using the unified syntax and
the same helper macros as Linux), modifying our custom-written libgcc
code for 64-bit division to support Thumb (removing some stale old files
that were never really used for clarity), and flipping the general
CFLAGS to Thumb (some more cleanup there as well while I'm at it).
BUG=None
TEST=Snow and Nyan still boot.

acpigen_patch_len doesn't really need its argument: length always includes
everything from length bytes to current pointer and never bytes before it.
Hence just infer all the info implicitly.
Argument is wrong in several places through the codebase but ACPI parsing
is lax enough to swallow incorrect SSDT. After this function is used throughout
the codebase, these issues will be fixed.

If we find multiple LPC controllers, we want to tell the user that we'll
ignore all but the first. However, we use 'dev' in the message (the
current device found) instead of 'sb' (the one we want to use).
Fix the message by using 'sb' and break the loop right away in this
case. It's sufficient to tell the user once which LPC controller we'll
use.

The flags used to compile libgcc may make it incompatible with the code it's
linked against, and/or the hardware it's going to run on. Rather than try to
tease the right libgcc from the compiler, lets just leave it out and use our
own implementations of the necessary functions.
Most of these implementations were taken from the Linux kernel, except for
uldivmod.S which was taken from a CL originally written for U-Boot by
Che-Liang Chiou in December of 2010. It was modified to not use the CLZ
instruction on machines that don't have it, anything earlier than ARMv5. The
top block was taken from an earlier version of the same CL which didn't use
CLZ in that spot. The later block was written from scratch.
BUG=None
TEST=Built and booted into the bootblock on nyan. Ran a series of tests which
divided and modded a 64 bit value by various 32 bit values which were powers
of 2. Confirmed that this function was used and that the returned value was
correct. Printed decimal and hex versions of some values and verified that
they equaled each other. Built and booted on pit with serial enabled.
