📝 Walkthrough

Walkthrough

This pull request updates the ODROID-M1 board configuration by advancing boot versions from v2025.10 to v2026.01, introducing UMS-specific u-boot device tree patches, updating preboot LED indicators, modifying USB gadget configuration, and adding a kernel patch for GMAC Ethernet TXD timing delay adjustment.

Changes

Cohort / File(s)	Summary
ODROID-M1 Configuration config/boards/odroidm1.conf	Updated BOOTBRANCH_BOARD and BOOTPATCHDIR to v2026.01. Introduced new pre_config_uboot_target__odroidm1_patch_uboot_dtsi_for_ums patch hook for UMS device tree modifications. Revised preboot environment configuration with new LED indicator sequences. Modified USB/RockUSB gadget enablement logic.
Rockchip Device Tree Patch patch/kernel/archive/rockchip64-6.19/board-odroidm1-change-ethernet-TXD-timing-delay-value.patch	New patch file adjusting GMAC TXD timing delay value from 0x4f to 0x35 in rk3568-odroid-m1.dts for improved Ethernet performance.
