Use the rework101229 branch (minus the last 5 patches). There is lot of cleanup done in the header files and the ATMEL drivers. The at91sam9260(9xe)ek board builds fine and works. Use that as a template or reference what to do. You should *only* need to adapt board/*/files and your configs/<board>.h files. And of course updated entries in boards.cfg. Once the rework is done for *almost* *ALL* AT91 SoCs it will be put for review into mainline, probably for the 06.2011 U-Boot. Best Regards, Reinhard

[U-Boot] [PATCH 1/2] P4080/PBL: add support for boot from SPI flash.
by Shaohui Xie 09 Apr '11

09 Apr '11

PBL(pre-boot loader): SPI flash used as RCW(Reset Configuration Word) and PBI(pre-boot initialization) source, CPC(CoreNet Platform Cache) used as 1M SRAM where PBL will copy whole U-BOOT image to, U-boot can boot from CPC after PBL completes RCW and PBI phases.
