* ath79: add read support using spi-memLuiz Angelo Daros de Luca2020-04-141-0/+70
Reimplements read optimization on top of spi-mem. Similar to what 461-spi-ath79-add-fast-flash-read.patch used to do with the dropped flash read interface. It accelerate only fast-read op reading flash directly from memory mapped region. 'm25p,fast-read' must be set in order to use the new spi-mem. It improved read speed up to 3x on old devices (tplink,tl-wr2543-v1) while no speed improvement was noticed on newer devices like (tplink,archer-c7-v2).
