X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=c90b2c4fc9c3f5660a359377aabc1998456ae5b1;p=uclinux-h8%2Flinux.git

ARM: dts: stm32: Configure qspi's mdma transfer to block for stm32mp151

Configure qspi's mdma from buffer transfer (max 128 bytes) to
block transfer (max 64K bytes).

mtd_speedtest shows that write throughtput increases :
  - from 734 to 782 KiB/s (~6.5%) with s25fl512s SPI-NOR.
  - from 4848 to 5319 KiB/s (~9.72%) with Micron SPI-NAND.
