Hi,
v6:
allow to pass the fstype for mount (omap usbfs)
v5:
rebase on Sacha SHELL_NONE patch
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 Sacha patch for SHELL_NONE
The following changes since commit a0a9331ba745418f1e7871f5bd707e3cc7e89902:
startup: call a barebox_main function pointer at the end of the startup (2013-01-17 11:56:24 +0800)
are available in the git repository at:
git://git.jcrosoft.org/barebox.git delivery/at91_bootstrap
