Hi:

I'm using u-boot v1.1.4. I wanted to remove any optimization to make debug simpler and the only optimization I have found was "-Os" option in the config.mk file; below is the change I've done:

112c112 < OPTFLAGS= -Os #-fomit-frame-pointer ---

OPTFLAGS= #-Os #-fomit-frame-pointer

Unfortunately after that change link is always failing - certain inline functions (not all) somehow cannot be resolved:

What can be a problem? Only PCI part looks not happy...
