[Buildroot] AT91SAM9260 and u-boot

[Buildroot] AT91SAM9260 and u-boot

[Shai Lifshitz]

I am trying (without much success...) to configure the buildroot 
toolchain, 
to fit the 4K boot memory.

maybe someone did it already and is willing to send me the '.config' file?
or maybe someone can tell me what to choose in the following options:

- target
    * arm
    * armeb    <--- is it big-endian?

-target architecture variant:
    * arm610
    * arm710
    * arm720t
    * arm920t
    * arm922t
    * arm926t
    * arm1136jf_s
    * arm1176jz-s
    * arm1176jzf-s
    * sa110
    * sa1100
    * xscale
    * iwmmxt
-target ABI
    * OABI
    * EABI     <--- is it with no floating-point HW?

Sincerely

The AT91SAM9260 support is not *fully* functional just yet (working on it),
so you are better off going to www.at91.com and look in the Linux Forum
for the buildroot script.
This will build an at91bootstrap which will fit into 4kB.

It is building with arm, generic-arm, OABI and NWFPE
