What am I missing?
I wonder if this has always been an underlying problem. Looking at drivers/mtd/nand/raw/am335x_spl_bch.c we've always had nand_page_size() return nand_to_mtd(&nand_chip)->writesize and I assume that should have been being set to CONFIG_SYS_NAND_PAGE_SIZE but I don't see that as the case. If you change nand_page_size to just return CONFIG_SYS_NAND_PAGE_SIZE or nand_init to set writesize to CONFIG_SYS_NAND_PAGE_SIZE does it then work again? -- Tom
