You're headed down the wrong path, arch/ppc/boot/simple and U-Boot (and PPCBoot of course) are mutlally exclusive. What you want to do is look at the embed_config file and define an embed_config function (iirc) to fill out the bd_t struct with the appropriate values. Then just 'make zImage' and, depending on how your firmware works, load the image into memory w/o the ELF header and jump to where it was loaded. -- Tom Rini http://gate.crashing.org/~trini/ ** Sent via the linuxppc-embedded mail list.
