Subject: ath79: increase SPI frequency for OCEDO boards
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5b58545f4470989b0e2243df5007e5fb29a85d21;p=openwrt%2Fstaging%2Frmilecki.git

ath79: increase SPI frequency for OCEDO boards

The MX25L12805D used on all ath79 OCEDO boards supports clock
speeds up to 50 MHz.

Thus, we can increase the maximum SPI frequency the flash chip is
controlled at to 50 MHz, increasing transfer speed.
