Subject: u-boot-sam460ex: build fixes
Forwarded: https://lists.nongnu.org/archive/html/qemu-devel/2025-01/msg00767.html
Fixes or works around numerous build issues and one real bug.
Most are due to new defaults in gcc (in debian), like
-Werror=implicit-function-declarations (there are a lot of missing decls)
-Werror=incompatible-pointer-types (function types mismatches)
-Werror=int-conversion (free int <=> pointer conversion)
Bug-Debian: https://bugs.debian.org/1075428
