Hi,

	v4:
	 make the code arm & mips supported for barebox head detection

	v3:

	send correct patch series and pull

	can we have it on master the v2 does not cange much since v1

	v2:
	 fix whitesapce
	 fix comment
	 fix command default

	This patch serie introduce a common bootstrap code
	aka xloder for TI and at91bootstrap for Atmel
	to barebox

	As I do not have with me right now a TI platform I did not switch
	it to the new generic bootstrap code.

	On at91 add it on the calao usb-a9263 test on nand and spi
	This patch serie depends on the previous at91 patch series

The following changes since commit cef34886b745cf3f6dff55bf326e29a5857b2206:

  graphic_utils/fb_open: fix fbsize (2013-01-16 21:33:14 +0100)

are available in the git repository at:

From: Jean-Christophe PLAGNIOL-VILLARD @ 2013-01-19 16:37 UTC (permalink / raw)
  To: barebox

This will allow to have a generic code to create different bootstrap

As example
Barebox as TI Xloader
Barebox as AT91 Bootstrap

This will allow to boot from NAND/MMC and others.
This version of bootstrap is a non shell version of barebox compressed by the
pbl.

Is this not the same like:
return is_barebox_mips_head(head); ?

Or is there some side effects during the first call of
is_barebox_mips_head(head)?

With the bootstrap code it's still too easy to break compilation. For
example if the usb_a9263_128mib_bootstrap_defconfig is selected and then
hush is enabled manually in menuconfig we end up with multiple
definitions of run_shell. I just sent a startup related cleanup series
that makes this less dependent on Kconfig magic (only first patch is
needed for this). Could you base your series on this one?
