Looking at the "arch/ppc/platforms/4xx/sequoia.c" from 2.6.14 MontaVista, I also see ECC error handling, a Serial RTC device, UART4 to UART11. It doesn't look like those are supported in the current "arch/powerpc/platforms/44x/sequoia" ?

Regarding the nftd NAND driver, I see a device table hookup in "arch/powerpc/platforms/44x/warp-nand.c".  Am I right in saying that file is a perfect template from which to generate sequoia-nand.c ?

thanks,
Steve
