tested on STM32MP135F-DK board, stm32mp13_defconfig.
I have a dependency with patch "firmware: scmi: fix the multi channel support with CCF"
http://patchwork.ozlabs.org/project/uboot/patch/20220930093635.1.I38e66d7935...
This this patch the SD-Card boot is OK with 2 traces :
1- because USBPHY is not yet present in DT:
clk_register: failed to get ck_usbo_48m device (parent of usbo_k)
2- the console trace is pertubated by UART RESET introduction in DT
=> the UART FIFO is not flush before the probe after relocation
and the reset of HW device
Clocks: - MPU : 650 MHz - AXI : 266.500 MHz - PER : 24 MHz - DDR�Core: 165 devices, 23 uclasses, devicetree: board MMC: STM32 SD/MMC: 0
For information "clk dump" command cause a crash because the SCMI clock
are not probed when clk_get_rate is used, but I prepare a patch to avoid this issue.
Thanks Patrick
