📝 WalkthroughWalkthroughThe PR migrates RK3506 U-Boot builds to v2026.07. It adds SoC support, shared device-tree infrastructure, board defconfigs, board-specific device trees, clock and SARADC fixes, SPL reservations, OP-TEE handling, and updated ArmSoM Forge1 identifiers. ChangesRK3506 U-Boot migration
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This update changes RK3506 boot memory layout, OP-TEE behavior, and ADC clock programming; unresolved paths can cause boot failures, reduce or misplace usable memory, or produce incorrect peripheral timing. The PR is not merge-ready until these correctness issues are fixed or explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 172-186: Update rkcommon_set_header0_v2 to use the resolved
spl_info entry rather than comparing params->imagename directly with "rk3506";
add the RK3506 SPL load address to struct spl_info and assign
hdr->images[i].address from that resolved value for the second image. Remove the
unnecessary null guard while preserving the default address for other images and
platforms.
In
`@patch/u-boot/v2026.07-rk3506/defconfig/luckfox-lyra-zero-w-rk3506b_defconfig`:
- Line 18: Add CONFIG_SARADC_ROCKCHIP=y and CONFIG_DM_SPI=y to the defconfig
alongside the existing CONFIG_CMD_ADC entry, preserving the current Rockchip SFC
and SPI NAND configuration without adding CONFIG_SPI_FLASH.
In
`@patch/u-boot/v2026.07-rk3506/rockchip-rk3506-Update-ENV_MEM_LAYOUT_SETTINGS.patch`:
- Around line 46-52: Update the ENV_MEM_LAYOUT_SETTINGS values for
ramdisk_addr_r and kernel_comp_addr_r so their buffers do not overlap during
compressed-kernel decompression, and size/place both ranges to fit within the
smallest supported RK3506G1 DRAM configuration. Keep pxefile_addr_r above the
CFG_SYS_SDRAM_RESERVE boundary, accounting for the current reservation.

maybe add an rewrite-uboot-patches to normalize them but otherwise looks good.
I wonder about having -u-boot.dtsi's in the same dirs just works? (I've been using separate dir for them)
