This patch runs basic NAND initialization code on Proto 0.2 boards which have been reworked for NAND. It makes sense to do this in coreboot for two reasons: - In general, it is reasonable for coreboot to initialize clocks and such in preparation for depthcharge's use. Waiting times can be pooled, and the initialization itself here is very fast. - There is a kernel bug which requires that the clock is already initialized before the kernel loads NAND support. coreboot is a more sensible place to put a workaround than depthcharge because depthcharge initializes things lazily, but when booting from USB, depthcharge won't need to look at NAND. This change involves bringing in an additional header file, ebi2.h, from U-Boot. TEST=Booted a kernel from USB and verified that NAND came up without any depthcharge hacks, whereas previously a USB-booted kernel would be unable to access NAND even with the same drivers compiled in due to an initialization failure.
