Merge tag 'for-linus-20121009' of git://git.infradead.org/mtd-2.6

10f39f04 · Linus Torvalds <[email protected]> · 2012-10-10 10:51:35 +09:00

Pull MTD updates from David Woodhouse:

 - Disable broken mtdchar mmap() on MMU systems
 - Additional ECC tests for NAND flash, and some test cleanups
 - New NAND and SPI chip support
 - Fixes/cleanup for SH FLCTL NAND controller driver
 - Improved hardware support for GPMI NAND controller
 - Conversions to device-tree support for various drivers
 - Removal of obsolete drivers (sbc8xxx, bcmring, etc.)
 - New LPC32xx drivers for MLC and SLC NAND
 - Further cleanup of NAND OOB/ECC handling
 - UAPI cleanup merge from David Howells (just moving files, since MTD
   headers were sorted out long ago to separate user-visible from kernel
   bits)

  - #address-cells, #size-cells : Must be present if the device has
    sub-nodes representing partitions (see below).  In this case
    both #address-cells and #size-cells must be equal to 1.
+ - no-unaligned-direct-access: boolean to disable the default direct
+   mapping of the flash.
+   On some platforms (e.g. MPC5200) a direct 1:1 mapping may cause
+   problems with JFFS2 usage, as the local bus (LPB) doesn't support
+   unaligned accesses as implemented in the JFFS2 code via memcpy().
+   By defining "no-unaligned-direct-access", the flash will not be

 For JEDEC compatible devices, the following additional properties
 are defined:
