Subject: ramips: decrease SPI frequency for Phicomm K2P
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=857ea3f690aba8513b356926d9c430adafc7c50b;p=openwrt%2Fstaging%2Fdedeckeh.git

ramips: decrease SPI frequency for Phicomm K2P

Some K2P comes with the worse boards with GD25Q128 (may be A2), which
only works with 50MHz frequency and less. Reduce spi frequency so that
these routers can boot.
remove m25p,fast-read because it isn't needed for 50MHz SPI.
