[U-Boot] [RFC PATCH 1/2 v2] nand: allow delayed initialization

Would it not be esier to rename your nand_delayed_init() into
nand_init(), and add a "#ifndef CONFIG_SYS_NAND_DELAYED_INIT" around
the current call to nand_init()?

Question: is there a risk of problems with boards that have the
environment in NAND?

Best regards,
