Hello Robert,
2008/8/9 Remy Bohmer <[EMAIL PROTECTED]>:
> This bootstrap package is required on at91sam* boards where
> dataflash/nandflash
> is used to boot from. In these cases the internal bootROM of the AT91 core is
> used to boot the board with.
>
> Patch Version 2:
> * Cleanup of Kconfig files
> * Added patch to align U-boot load addr to dataflash sector boundaries
> This is what mainline U-boot demands, and what clearly is a bug in the
> original Atmel's Bootstrap code.
> * Added Kconfig option for selection between dataflash and nandflash
> * Upgraded template of Makefile.

I was wondering: Did you already found some time to look at this patch?
Kind regards,
Remy
