The ROM boot on OMAP reads the first 4 blocks searching for the SPL, in production is a practice flash the SPL 4 times. OneNAND/NAND devices can have different block sizes and the OMAP ROM boot supports block sizes from 64KB to 512K. For IGEP boards in particular, at least there are boards that have block size of 128K and 256K. What I would meant here is set as default the mtdparts variable to reserve 2M for SPL, just to cover all the cases.
mtdparts=mtdparts=gpmc-nand.0:2m(SPL),-(UBI)\0
So far there was no ack or nack to yesterday's proposal making that dynamic; Both boot ROM and ubispl code thinks in terms of eraseblocks, only mtd needs fixed offset. So I'd like to see this offset calculated as 4*block_size, not some "worst case" value...
