cb93481268 tegra2: Implement SPI / UART GPIO switch
The Tegra2 Seaboard has the unfortunate feature that SPI and the console
UART are multiplexed on the same pins. We need to switch between one
and the other during SPI and console activity.

This new file implements a switch and keeps track of which peripheral
owns the pins. It also flips over the controlling GPIO as needed

a proper Makefile there and remove the direct board.o include from

076cd49ad1 arm926ejs: remove noop flush_dcache_all function
Commit 2f3427c added noop cache functions implementation for arm926ejs
to fix compilation of drivers depending on these functions (DaVinci
EMAC in particular).

Unfortunately, the bug was introduced: noop implementation calls
dcache_disable which calls flush_dcache_all which in turn calls
dcache_disable thus creating an infinite loop.

This patch removes noop implementation for flush_dcache_all, we already
have default one in arch/arm/lib/cache.c and it should be used instead.

69370d144a x86: Refactor the zboot innards so they can be reused with a vboot image
If vboot successfully verifies a kernel, it will leave it in place and
basically ready to boot. The zeropage table which is part of the x86 boot
protocol is at the end of the kernel, though, instead of the beginning, and
because the image is already in place there's no need to copy it around.
This change refactors the code which implements the zboot command so that
the configuration of the zeropage table and loading the pieces of the
kernel into memory are done separately. Also, because the command line goes
before the zeropage table in vboot which is somewhat incompatible with the
normal protocol, where to put the command line is a now a parameter instead
of being hard coded.

f08fa7a201 x86: Add infrastructure to extract an e820 table from the coreboot tables
Also approximate the size of RAM using the largest RAM address available
in the tables. There may be areas which are marked as reserved which are
actually at the end of RAM.

233dbc1194 x86: Add support for booting Linux using the 32 bit boot protocol
This change conditionally modifies the zboot command so that it can use the
32 bit boot protocol. This is necessary because the 16 bit realmode entry
point assumes that it can call BIOS services which neither coreboot nor
u-boot provide.

d3a2bc3fd1 x86: Clean up the x86 zimage code in preparation to extend it
This change cleans up some formatting issues in the zimage handling code, and
converts it from using offsets added to a base pointer to using the available
structure definitions which were already being included.
