From fcda974e36033ad5331a9b4a4a551af4e141ad7d Mon Sep 17 00:00:00 2001 From: Quentin Strydom Date: Sat, 20 Jun 2026 16:07:24 +0100 Subject: arm: aspeed: Fix AST2600 SPL external DTB alignment For AST2600 SPL with CONFIG_SPL_SEPARATE_BSS=y and CONFIG_OF_SEPARATE=y, fdt_find_separate() expects the appended control DTB at _image_binary_end. The AST2600 SPL linker script aligned _image_binary_end via the .binman_sym_table section. In builds where that section has no emitted contents, objcopy -O binary does not include the alignment bytes in spl/u-boot-spl-nodtb.bin. This causes the nodtb binary to end before _image_binary_end, so the appended DTB is placed too early. On evb-ast2600 this produced: sizeof(spl/u-boot-spl-nodtb.bin) = 0xc92c _image_binary_end = 0xc930 SPL then looked four bytes past the FDT header and failed with: Missing DTB No serial driver found Move the 8-byte alignment into the preceding emitted __u_boot_list section so the objcopy output and _image_binary_end agree.
