Subject: u-boot-sam460ex: remove compiler-gccN.h #include
Date: Wed, 19 Nov 2025 23:30:38 +0300
include/linux/compiler*.h are taken from old linux, and
only supports gcc4. However, the gcc-version-dependent
definitions in there aren't actually used in the code,
except of uninitialized_var macro - which is defined in
the fallback case to the same value. So there's no
point in including the gcc-version-specific header,
which fails when building this code with a more recent
version of gcc.
This patch removes just the #include statement
(and the helper definitions), but not compiler-gcc4.h
header itself. This makes the change small, and allows
compilation of u-boot-sam460ex code by something more
recent than ancient gcc.
