To make things more clear: NAND flash Samsung K9F1G08U is defined in both $(uboot)/drivers/mtd/nand/nand_ids.c and $(uboot)/include/linux/mtd/nand_ids.h, latter is included with CFG_NAND_LEGACY defined. It confuses me, I don't understand is my flash legacy device or rather new one? :-)
IIRC then your NAND chips should be supported in the U-Boot NAND driver without any changes.
Okay. There is another thing confusing me is - almost all ports implement board specific support of flash in $(uboot)/board/board_name/flash.c or $(uboot)/board/board_name/nand.c (NAND specific).
What is the rationale to separate them in such a way -- flash.c is for NOR, boot flash etc. only and all NAND stuff apart? Does 'flinfo' print information about ANY available flash -- but on the other hand, do_flinfo() in $(uboot)/common/cmd_flash.c uses 'flash_print_info()' defined in target's flash.c
Hmm.. completely confused.
Hopefully somebody can bring me out in the light :)
