mtd: physmap_of: Add read-only fallback

2015-01-10T07:22:40Z

Previously, when probing a CFI chip which was write-protected at the hardware level, the probe would fail due to the fact it could not put the chip into QUERY mode. This would result in no MTD devices being created. Add a fallback to probe using the map_rom driver if the user-selected probe fails.

mtd: physmap_of: fix potential NULL dereference

2014-12-13T03:12:16Z

On device remove, when testing the cmtd field of an of_flash struct to decide whether it is a concatenated device or not, we get a false positive on cmtd == NULL, and dereference it subsequently. This may occur if of_flash_remove() is called from the cleanup path of of_flash_probe(). Instead, test for NULL first, and only then perform the test for a concatenated device.

mtd: maps: drop owner assignment from platform_drivers

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

mtd: physmap_of: Add non-obsolete map_rom probe

2014-09-22T17:13:13Z

Previously, the only way to map a NOR device as a simple ROM was to use the obsolete "direct-mapped" compatible binding (which further requires device_type = "nor" and probe-type = "NOR" properties). This patch adds an "mtd-rom" compatible binding to the "map_rom" probe type. Signed-off-by: Aaron Sierra Signed-off-by: Brian Norris

mtd: physmap_of: Fix ROM support via OF

2014-09-22T17:13:11Z

The "ROM" and unknown probe types within the obsolete "direct-mapped" probe function used the nonexistent "mtd_rom" probe instead of the intended "map_rom". Signed-off-by: Aaron Sierra Signed-off-by: Brian Norris

mtd: gpio_flash: handle case where offset + len exceeds the window size

2014-08-19T18:53:10Z

Fix the bug in handling gpio flash read/write when offset + len from MTD exceeds the window size Signed-off-by: Aaron Wu [Brian: made some commentary edits. Also note that the BUG_ON() was provably false for all non-negative inputs (since x % y <= x), so we dropped it.] Signed-off-by: Brian Norris

mtd: use NULL instead of 0 for an address

Use NULL instead of 0 when returning an address. This fixes a sparse warning. Signed-off-by: Martin Kepplinger Signed-off-by: Brian Norris
