[PATCH 3/4] mmc: fsl_esdhc: add pulse width detection workaround

2021-03-17 Thread Michael Walle
HS400 mode on the LS1028A SoC isn't reliable. The linux driver has a workaroung for the pulse width detection. Apply this workaround in u-boot, too. This will make HS400 mode work reliably on the LS1028A SoC. Signed-off-by: Michael Walle --- arch/arm/cpu/armv8/fsl-layerscape/Kconfig | 1 + driv
