Hi,
Sorry if the problem is too newbie, but I tried to build upstream U-boot
for RockPro64 (which uses RK3399 SoC) using the evb-rk3399 defconfig.
My adventure starts good, it boots properly. However SDMMC doesn't work

Hi,
Although recent U-boot upstream has merged the rk3399 ram patchset to
initial DDR4 properly, but strangely I can still trigger SError for

(v5.4-rc). The dmesg is attached at the end.

This patch introduces a new function, get_path_in_subvolume(), which
