Masahiro Yamada d8753571b2 sizes.h: move include/sizes.h to include/linux/sizes.h
This file originates in Linux.  Linux has it under include/linux/
directory since commit dccd2304cc90.
Let's move it to the same place as well in barebox.

This commit was generated by the following commands:

  find -name '*.[chS]' | xargs sed -i -e 's:<sizes.h>:<linux/sizes.h>:'
  git mv include/sizes.h include/linux/

Lucas Stach 4f381b1aaa ARM: change signature of barebox_arm_entry
Mostly to make it clear that boarddata needs to be
something we can dereference.

As this is a pretty invasive change, use the opportunity
to make the signature 64bit safe.

Sascha Hauer 65504828dd ARM: omap: fix omap_save_bootinfo
omap_save_bootinfo derefences the argument passed to barebox without
checking it for validity. This breaks 2nd stage booting where r0
is undefined. The best we can do is to check whether the pointer is
somewhere in SRAM and is word aligned. This at least makes sure that
we do not oops. This introduces SoC specific xxx_save_bootinfo variants
since the SRAM addresses/sizes differ between SoCs.

Additionally fix the prototype for omap_save_bootinfo. It uses r0, so
it must be passed this variable.

Teresa Gámez c5c875ab7f arm: omap: store boot source info from ROM loader
The ROM loader passes the address of a buffer to the MLO in
register 0. Store this data so we can find the boot source later.
On the same way the bootinformation are passed to the barebox,
then. It has to be enshured that r0 contains always the
buffer or the boot source detection will not work.

Applied this on all OMAPs. This patch is based on work of
Jan Luebbe <jlu@pengutronix.de>.

Compile tested on all OMAP boards.
Tested on pcm049, phyCARD-A-L1 and pcm051.

Sascha Hauer 1c240cd234 ARM OMAP boards: switch to barebox_arm_entry
All boards use hardcoded SDRAM addresses, copied from the board init file.
OMAP3 boards are a bit special, they had a SoC specific reset() function. This
is renamed to omap3_invalidate_dcache() and called from the board lowlevel init
code now.

Jan Luebbe faf7b7af6e ARM: give boards control of the reset entry point
On some SoCs (for example AM35xx), the ROM bootloader passes useful
information in r0 when jumping to barebox.

To avoid overwriting this in the generic reset code, we introduce
common_reset as a C function and as an assembler macro. This is then
called form the reset entry point (either in common or in board code).

This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.
