The Odroid M2 requires mainline kernel as the Rockchip vendor 6.1 BSP has no support for this board. Uses Armbian's pre-built U-Boot binary since building from source with Buildroot's toolchain produces binaries that cause SError kernel panics during paging_init. Board config: - Standalone target (make odroidm2-build), separate from rk3588 - Mainline kernel 6.18.21 with Armbian's tested defconfig - In-tree DTS (rockchip/rk3588s-odroid-m2), no custom DTS needed - Pre-built U-Boot from Armbian (v2025.10, BL31 v1.48, DDR v1.18) - Serial console ttyS2 at 1500000 baud (matching Armbian) - 14 kernel patches from Armbian rockchip64-6.18 patch set Kernel patches (from Armbian): - 4 Odroid M2 board DTS fixes (ethernet PHY, HDMI audio, USB-C OTG, Vu8S panel) - 7 USB-C/TCPM/DWC3 driver fixes (role switching, PHY power tracking, PD capabilities, extcon bridge) - 1 DRM DMA mask fix (required for GPU on 16GB systems) - 2 RK3588 platform fixes (clock division overflow, OPP nodes) Build system registration: - Config.in: new target with capability/feature lists - batocera-system.mk and batocera-configgen.mk: arch mappings - 7 emulator .mk files: ODROIDM2 added to RK3588 platform - alllinuxfirmwares.mk and rockchip-mpp.mk: target added - Excluded ecwolf (Bitbucket submodule auth issue)

Summary
Add Hardkernel ODROID-M2 (RK3588S) as a standalone build target.
make odroidm2-buildTested
Notes for maintainers
This board needs a standalone target because the existing rk3588 vendor kernel (6.1) has no Odroid M2 support. The approach mirrors how rk3568 uses mainline kernel separately from the rk3588 vendor build.
U-Boot is pre-built from Armbian (like odroid-m1, bananapi-m7) because Buildroot's toolchain produces non-booting binaries for this board.
Open to feedback on the approach — happy to rework if needed.
