[U-Boot] is some old content in arch/arm/include/asm/{memory, setup}.h removable?

poking around in arm header files and it seems that some stuff there is old enough to be removed.

first, entire content of arch/arm/include/asm/memory.h is enclosed in "#if 0"; git blame tells me it's been like that since 2003.

also, arch/arm/include/asm/setup.h still contains structure for the old, deprecated way to pass parameters to the kernel -- does anyone still use/need that? just curious.
