NAND: rearrange ONFI revision checking, add ONFI 2.3

2011-04-15T20:53:11Z

This patch sync with Brian's patch on Linux in nand_flash_detect_onfi() commit b7b1a29d94c17e4341856381bccb4d17495bea60 Author: Brian Norris Date: Sun Dec 12 00:23:33 2010 -0800 mtd: nand: rearrange ONFI revision checking, add ONFI 2.3 In checking for the ONFI revision, the first conditional (for checking "unsupported" ONFI) seems unnecessary. All ONFI revisions should be backwards-compatible; even if this is not the case on some newer ONFI revision, it should simply fail the second version-checking if-else block (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we move our "unsupported" condition after having checked each bit field. Also, it's simple enough to add a condition for ONFI revision 2.3. Note that this does *NOT* mean we handle all new features of ONFI versions above 1.0.

atmel_nand: don't require CONFIG_SYS_NAND_ENABLE_PIN

2011-04-01T19:49:08Z

If NCE is hooked up to NCS3, we don't need to (and can't) explicitly set the state of the NCE pin. Instead, the controller asserts it automatically as part of a command/data access. Only "CE don't care"-type NAND chips can be used in this manner. Signed-off-by: Michael Trimarchi Cc: Scott Wood Cc: Reinhard Meyer

NAND: add support for reading ONFI page table

2011-04-01T19:49:08Z

This patch adds support for reading an ONFI page parameter from a NAND device supporting it. If this is the case, struct nand_chip onfi_version member contains the supported ONFI version, 0 otherwise. This allows NAND drivers past nand_scan_ident to set the best timings for the NAND chip.
