AT91bootstrap 3.0 support booting from SD-Card.
Signed-off-by: Ulf Samuelsson<[email protected]>
I always wonder why AT91bootstrap patches are not merged in Atmel repository.
Regards,
AT91bootstrap-1.x is the offical Atmel bootstrap that
can be downloaded from Atmels homepage.
This cannot be compiled by an arm-linux compiler,
since it relies on newlib.
It also has a strange user interface, in that you
have to step down deep into the directory tree
and then type make, using a hard wired configuration
in a header file.
The at91bootstrap-2.x series has been generated by me, and
I am not part of the AT91 product line and cannot
change the official version.
The goal of this bootstrap was to be able to compile
using an arm-linux compiler, and since then Kconfig
has been added and a few other niceties.
There is yet another "hidden" at91bootstrap which
is present in the AT91 softpacks.
This has some nice features, including SD-Card boot,
but again, not compilable by an arm-linux compiler.
The at91bootstrap-3.x series is a new Atmel project which
is intended to merge the functionality of all previous versions,
and be compilable on arm-linux.
It is developed by the AT91 product line from my 2.x codebase.
The patches to submitted for this package are my code.
I have made them aware of the patches and I think
that the patches will be merged over time, but
i cannot tell when.
