This patch set does not include any such, right? Anyway, for my tests I took them from linux-next on kernel.org. However, I could not get the SD card working apart from it booting U-Boot off of it: U-Boot SPL 2024.04-rc3-00015-g7186697f1ff (Feb 27 2024 - 14:27:29 +0100) SYSFW ABI: 3.1 (firmware rev 0x0009 '9.1.9--v09.01.09 (Kool Koala)') Initialized 4 DRAM controllers SPL initial stack usage: 13416 bytes Trying to boot from MMC2 Authentication passed Authentication passed Authentication passed Loading Environment from nowhere...
