Re: [PATCH] arm64: zynqmp: Handle MMC seq number based on boot device

po 31. 5. 2021 v 9:52 odesílatel Michal Simek michal.simek@xilinx.com napsal:

K26 has EMMC and SD and default 0 is not working when system is booting out of SD which is controller 1. Add controller autodetection via mmc_get_env_dev(). The same code is used for distro_boot selection done in board_late_init(). bootseq variable can't be reused because this is called so late.
