[PATCH v4 0/5] Refactor bch settings and support large oob NAND

[Han Xu]

These series of patches refactor the gpmi bch setting function and
introduce a new way to set bch for large oob(oobsize > 1KB) NAND.

Code changes don't affect the default bch behavior but users may add DT
flag to use NAND chips required minimum ecc strength. More strict ecc
strength check added to make sure ecc strength is strong enough. For
some NAND chips that oobsize larger than 1KB, a new way to set bch was
introduced, which may use a separate ecc for meta. In this case, the
data0_size in BCH_FLASH0LAYOUT0 and datan_size in BCH_FLASH0LAYOUT1 need
to be presented in dedicate variables.
