Subject: ramips: unielec-u7621-01: Increase SPI frequency to 50MHz
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=443e3bd1c6e61aa39f4fc176b22ad2d75f33bcb4;p=openwrt%2Fopenwrt.git

ramips: unielec-u7621-01: Increase SPI frequency to 50MHz

Flash: 16MB SPI NOR flash (Macronix MX25L12805D)

Based on the manufactured datasheet this chip is capable of 50MHz.

We dont enable fast-read as mt7621 are only capable of 44mhz in a read state.

Tested on this unit without any issues.
