Mon Jun 17 09:44:22 UTC 2019
This driver needs modification to work with new soc,
like ls1028, since bitmap of RCFG is changed to
RESV[7:5] LIVE[4] WDEN[3] RESV[2:1] GO[0]
000 1 0 00 0
Also the RCW location is moved to only dutcfg0.
RESV[7:4] RCWSRC[3:0]
1111 configurable
Following commands should be functional now
qixis_reset
qixis_reset sd
qixis_reset qspi
qixis_reset emmc
