2013-04-05mtd: nand_ids: use size macrosArtem Bityutskiy
Use the convenient 'SZ_8K' and 'SZ_16K' macros for the eraseblock size in the NAND IDs table. This is a little more readable. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2013-04-05mtd: nand_ids: improve LEGACY_ID_NAND macro a bitArtem Bityutskiy
Notice that all the flashes belonging to the "legacy ID" class have 512 bytes NAND page. This means we may simplify the 'LEGACY_ID_NAND()' macro as well as the NAND ID table a little.

2013-04-05mtd: nand_ids: introduce helper macrosArtem Bityutskiy
Introduce helper macros for defining NAND chips. These macros do not really add much value in the current code-base. However, we are going to add full ID support which adds some more complexity to the table, and helper macros become useful for readability.

2013-04-05mtd: nand: remove few tiny page NAND bitsArtem Bityutskiy
NAND flashes with 256 bytes NAND pages are so old that probably do not exist any more. Let's remove few related pieces of code and forget about them forever. The assumption will be that 512 bytes NAND page size is the minimum possible.

No drivers use auto-increment NAND, so kill the NO_AUTOINCR option entirely. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2011-10-31mtd: Add module.h to drivers users that were implicitly using it.Paul Gortmaker
We are cleaning up the implicit presence of module.h that these drivers are taking advantage of. Fix them in advance of the cleanup operation. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-09-11mtd: rename MTD_OOB_* to MTD_OPS_*Brian Norris
These modes are not necessarily for OOB only. Particularly, MTD_OOB_RAW affected operations on in-band page data as well. To clarify these options and to emphasize that their effect is applied per-operation, we change the primary prefix to MTD_OPS_.

2011-05-25mtd: convert remaining users to mtd_device_register()Jamie Iles
The older add_mtd_device()/add_mtd_partitions() and their removal counterparts will soon be gone. Replace uses with mtd_device_register() and mtd_device_unregister().

2010-05-14mtd: sm_common: split smartmedia and xD tableMaxim Levitsky
2GB xD card, and 4MB SmartMedia ROM card share same ID, so to make both work split xD and smartmedia ID tables. Hardware driver must be able to know which type it handles (and probably just one).
