When adding new header from zipl/include to a .c file within zipl/boot
a compiler error appears
stage3.c:16:10: fatal error: zipl.h: No such file or directory
#include "zipl.h"
^~~~~~~~
compilation terminated.
CC zipl/boot/stage3.o
This is because the rule to generate dependencies (*.o.d) does not use
the CFLAGS_BOOT. Thus it cannot find the header and fails. Note this
only applies to the dependency generation, the actual build succeeds.
To fix this rename the CFLAGS_BOOT to ALL_CFLAGS. Using ALL_CFLAGS
instead of e.g. ALL_CPPFLAGS is important to also overwrite flags given
on the commandline via OPT_FLAGS, e.g.
make V=1 OPT_FLAGS="-D__FOO__"
While at it also remove the unused and wrong '-D__ASSEMBLY__'.
Fixes: 5a6605fe ("zipl: Ensure that boot loader CFLAGS are not overwritten")
Fixes: aa913b1e ("build process: Add automatic dependency generation")
