[OpenWrt-Devel] [PATCH v2 1/1] ar71xx: Remove mtd cfi_cmdset_0002 force word write patch

[Tokunori Ikegami]

Currently the buffer write works as same with word write correctly.
So it looks that it is not necessary to force word write.
Also the write performance will be improved by the change to buffer write.
