# TODO(crosbug.com/16808) We hard-code u-boot's compiler flags here just
|
|
# temporarily. As we are still investigating which flags are necessary for
|
|
# maintaining a compatible ABI, etc. between u-boot and vboot_reference.

# As a first step, this makes the setting of CC and CFLAGS here optional, to
|
|
# permit a calling script or Makefile to set these.

# Flag ordering: arch, then -f, then -m, then -W
