| * [MTD] Fix default timeouts for Intel NOR flashDavid Woodhouse2007-02-09
| | | | | | | | | | | | | | | | | | | | In commit c172471b78255a5cf6d05383d9ebbf0c6683167a Nico switched to using common code for polling for command completion. Unfortunately he also used a common default timeout for both write and erase commands, despite the fact that erases can take a _whole_ lot longer. Use a more sensible default for erase timeout.

| | * [MTD] OneNAND: Select correct chip's bufferRAM for DDPAdrian Hunter2007-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OneNAND double-density package (DDP) has two chips, each with their own bufferRAM. The driver will skip loading data from the NAND core if the data can be found in a bufferRAM, however in that case, the correct chip's bufferRAM must be selected before reading from bufferRAM.

| | * [MTD] OneNAND: Amend write-verify to compare to original bufferAdrian Hunter2007-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When write-verify is enabled (CONFIG_MTD_ONENAND_VERIFY_WRITE), the data written is read back and compared. The comparison was being made between dataRAM buffers, but this does not verify that the data made it to the dataRAM correctly in the first place. This patch amends write-verify to compare back to the original buffer. It also now verifies sub-page writes.

There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
