When building the boot wrapper assembly files with clang after commit648a1783fe("powerpc/boot: Fix boot wrapper code generation with CONFIG_POWER10_CPU"), the following warnings appear for each file built: '-prefixed' is not a recognized feature for this target (ignoring feature) '-pcrel' is not a recognized feature for this target (ignoring feature) While it is questionable whether or not LLVM should be emitting a warning when passed negative versions of code generation flags when building assembly files (since it does not emit a warning for the altivec and vsx flags), it is easy enough to work around this by just moving the disabled flags to BOOTCFLAGS after the assignment of BOOTAFLAGS, so that they are not added when building assembly files. Do so to silence the warnings.

# Makefile for making ELF bootable images for booting on CHRP

# Geert Uytterhoeven September 1997

# Based on coffboot by Paul Mackerras

# Simplified for ppc64 by Todd Inglett

|
|
# NOTE: this code may be built for 32 bit in ELF32 format even though
|
|
# it packages a 64 bit kernel. We do this to simplify the
|
|
# bootloader and increase compatibility with OpenFirmware.
|
|
#
|
|
# To this end we need to define BOOTCC, etc, as the tools
|
|
# needed to build the 32 bit image. That's normally the same
|
|
# compiler for the rest of the kernel, with the -m32 flag added.
|
|
# To make it easier to setup a cross compiler,
|
|
# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
|
|
# in the toplevel makefile.
