Commit Message

Wei Gao June 22, 2026, 7 a.m. UTC 
The dmidecode Makefile uses $(shell uname -m) to detect architecture, which 
returns the build host's arch (x86_64) during cross-compilation. This causes 
x86-only utilities (biosdecode, vpddecode, ownership) to be incorrectly built 
and installed on ARM targets.

On NVIDIA Tegra234, running biosdecode triggers a flood of CBB fabric 
DECODE_ERR interrupts (23,568+ printk messages dropped) by scanning 
non-existent x86 BIOS memory at 0xF0000-0xFFFFF.

Fix by passing TARGET_ARCH to the Makefile's MACHINE variable, so it correctly 
detects the target architecture and skips x86-only tools on ARM builds.
