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

Since we are adding a second file to board/nvidia/common, we create
a proper Makefile there and remove the direct board.o include from

Commit 2f3427cc 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.

This change finishes plumbing the initrd support built into the zboot
mechanism out to the command interface.

It also fixes a bug in the command declaration where the kernel size could
be passed as an optional second parameter but not enough arguments were
allowed.
Signed-off-by: NGabe Black <gabeblack@chromium.org>

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.

This change conditionally modifies the zboot command so that it can use the

u-boot provide.

This change cleans up some formatting issues in the zimage handling code, and

structure definitions which were already being included.
Signed-off-by: NGabe Black <gabeblack@chromium.org>

This change also forces the lib_sysinfo structure to be in the .data
section. Otherwise it ends up in the .bss section. U-boot assumes that it
doesn't need to copy it over during relocation, and instead fills that
whole section with zeroes. If we really were booting from ROM that would be
appropriate, but we need some information from the coreboot tables (memory
size) before then and have to fill that structure before relocation. We
skirt u-boot's assumption by putting this in .data where it assumes there
is still read only but non-zero data.

We already flush the kernel image after we've loaded it to ensure
visiblity to the other cores.  We need to do the same thing for the
ramdisk and device tree images.  In AMP boot scenarios we might not be
HW cache coherent with the secondary core that we are loading and
setting the ramdisk and device tree up for.  Thus we need to ensure
we've flushed the regions of memory utilized by ramdisk and device tree
so the loadding and any modifications (from decompression or fdt updates)
are made visible to the secondary cores.

U-boot itself generally builds with -nostdinc.  This is because the
bootloader needs to be completely standalone.  In the sandbox arch
though, we need a little bit of code to glue the u-boot world to the
host operating system, and we need to be able to access the host
libc's headers in order to do so.

Currently, we're using -I/usr/include to workaround the global
-nostdinc, but that doesn't work for everyone and for all headers.
Instead, let's filter out -nostdinc when building the os.c code.

Without this patch, some distros hit errors such as:
