Subject: [PATCH] mtd: nand: mxs_nand_spl: refactor mxs_flash_ident
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
The existing `mxs_flash_ident()` is limited to identify ONFi compliant
NAND chips only. In order to support non-ONFi NAND chips refactor the
function and rename it to `mxs_flash_onfi_ident()`.
A follow-up patch will add `mxs_flash_full_ident()` which allows to use
the chip ID list to lookup for supported NAND flashs.
