2013-04-05mtd: m25p80: add entry for w25q128Rafał Miłecki
This device was reported over a year ago on OpenWrt mailing list in the thread [OpenWrt-Devel] RedBoot partition table with winbond m25q128vb (unfortunately, I can't find message id). Macpaul seemed to have problems with partition driver, but it seems the device was working OK.

2013-04-05mtd: m25p80: introduce SST_WRITE flag for SST byte programmingKrzysztof Mazur
Not all SST devices implement the SST byte programming command. Some devices (like SST25VF064C) implement only standard m25p80 page write command. Now SPI flash devices that need sst_write() are explicitly marked with new SST_WRITE flag and the decision to use sst_write() is based on this flag instead of manufacturer id.

2013-02-04mtd: m25p80: Flash protection support for STmicro chipsAustin Boyle
This patch adds generic support for flash protection on STmicro chips. On chips with less than 3 protection bits, the unused bits are don't cares and so can be written anyway. The lock function will only change the protection bits if it would not unlock other areas. Similarly, the unlock function will not lock currently unlocked areas. Tested on the m25p64.

2012-09-29mtd: m25p80: Disable 4KiB erase for s25sl032p, s25sl064pMarek Vasut
Quoting from the datasheet for S25FL064P, rev. 05, Nov 18 2011, § 9.17: "A 64 kB[sic] sector erase (D8h) command issued on 4 kB or 8 kB erase sectors will erase all sectors in the specified 64 kB region. However, please note that a 4 kB sector erase (20h) or 8 kB sector erase (40h) command will not work on a 64 kB sector." Referring further to Table 8.1 and Table 8.2, it is clearly seen that most of the sectors are 64KiB; therefore disable this 4KiB erase support since it's valid only on first/last sectors.

2012-03-27mtd: do not duplicate length and offset checks in driversArtem Bityutskiy
We already verify that offset and length are within the MTD device size in the MTD API functions. Let's remove the duplicated checks in drivers.

2012-03-27mtd: add leading underscore to all mtd functionsArtem Bityutskiy
This patch renames all MTD functions by adding a "_" prefix: mtd->erase -> mtd->_erase mtd->read_oob -> mtd->_read_oob ... The reason is that we are re-working the MTD API and from now on it is an error to use MTD function pointers directly - we have a corresponding API call for every pointer. By adding a leading "_" we achieve the following: 1. Make sure we convert every direct pointer users 2. A leading "_" suggests that this interface is internal and it becomes less likely that people will use them directly 3. Make sure all the out-of-tree modules stop compiling and the owners spot the big API change and amend them.
