[PATCH 0/3] Support SDMA mode on RPI4 target - 32bit

2020-01-22 Thread Jaehoon Chung
RPI4's SDHCI controller is supported SDMA mode. (Checked on kernel side) But It doesn't use on u-boot side. Then it's too slow about read/write performance. This patchset is supported SDMA mode on RPI4 target(32bit). - I didn't test on RPI4 64bit. Read/write time about 8MB file Before - Read : 1.
