From 77260b8cee40f3d874a0d692d1abe28c0d42662d Mon Sep 17 00:00:00 2001 From: Adrian Freihofer Date: Tue, 17 Feb 2026 17:39:02 +0100 Subject: [PATCH] siemens: capricorn: set max-frequency for usdhc1 This is required since commit aebb523a2381 ("mmc: mmc-uclass: Use max-frequency from device tree with default handling") and the related patches of the same series. The error observed without this change is: Autobooting in 3 seconds, press "" to stop EXT_CSD[179], PARTITION_CONFIG: BOOT_ACK: 0x0 BOOT_PARTITION_ENABLE: 0x1 (boot0) PARTITION_ACCESS: 0x0 (user) Loading from eMMC ...fit U-Boot SPL 2026.01-4238dcfcbfe (Jan 09 2026 - 08:19:45 +0000) For this example it's the following commands which does no longer work for larger images: ext4load mmc 0:1 0x88000000 boot/fitImage On latest master branch the problematic commit gets reverted with commit c4f5b1d4b037 ("Revert "mmc: mmc-uclass: Use max-frequency from device tree with default handling"") but for v2026.01 this fix is still required. Maybe it's anyway a good idea to have this property set explicitly.
