Hi,
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 9f7f67ca887b26a4488edf5fa171a78e142e0a5b:
at91: drop AT91_BASE_PIOx for soc specific one for none boot code (2012-12-29 01:37:47 +0800)
are available in the git repository at:
git://git.jcrosoft.org/barebox.git delivery/at91_bootstrap

This will allow to have a generic code to create different bootstrap
As example
Barebox as TI Xloader
Barebox as AT91 Bootstrap
