v1 is at <20190116174559.17416-1-a.fatoum@xxxxxxxxxxxxxx>.
I tried to strip down barebox, so the first stage can be device tree
based as well. It boots up to trying to load the first stage from MMC,
where it fails. As it's very annoying to debug when only having few bytes
to spare, I am not sure if it's worth it. Future barebox updates might
increase size and break it again, so the first stage is again non-device
tree, but OFDEVICE can be selected and the curious user (you?) can try
to get the size further down and fix the bootstrap failure.
This patch set applies on top of "ARM: at91: misc fixes and cleanup",
<20190116174559.17416-1-a.fatoum@xxxxxxxxxxxxxx>, which I sent out
earlier today.
Changes since v1:
- dropped removal of h32mx code, it was just touched by
ARM: at91: microchip-kz9477-evb: support first stage boot and might
be useful for future ports
- dropped removal of sama5d3_matrix.h, already mainline via
f722f2a12 ("ARM: at91: delete unused mach/sama5d3_matrix.h")
- added commit with BSD-1-Clause license text
- split the migration to the at91bootstrap header for SDRAM defines
into 3 separate commits for better comprehension as suggested by Sam
- arch-prefixed globally visible functions/defines
- copied over some helper functions from at91bootstrap for board init,
or moved them to headers, so board code can look more like at91bootstrap
board code
- moved some helper function into headers, so they can be used in
multiple boards in future
- replaced all __raw_{read,write}T with {read,write}T
- added separate entry point for first stage, like am335x does
- added build-time size check for first stage
- renamed _first_stage suffix to _bootstrap, for symmetry with
the other at91sam9261
- compressed the DTB
- added infrastructure for future device tree based first stage
- added documentation as suggested by Sam
- changed NAND partition layout in board code as suggested by Sascha
- stylistic fixes here and there
