Well, that's exactly what I meant. When you boot an upstream U-boot on a P1022DS, there is no support for NAND chips. The 'nand' command does not exist. You cannot build a u-boot.bin that will boot from NAND. That pretty much means "there is no NAND support". >>>>> However, I just tried the two SDK patches >>>>> that add it, and they apply cleanly, so that's an easy fix. >>> Which patches are those? >> >> powerpc/85xx: add SPI and SD builds for P1022DS >> powerpc/p1022ds: Add support for NAND and NAND boot > > I'm not sure what SPI and SD have to do with it...

I don't want the TPL work to hold up these patches. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
