prom_putchar() is used centrally in early printk infrastructure therefore
at least MIPS should agree on the function return type.
[paul.burton@mips.com:
- Include linux/types.h in asm/setup.h to gain the bool typedef before
we start include asm/setup.h elsewhere.
- Include asm/setup.h in all files that use or define prom_putchar().
- Also standardise on signed rather than unsigned char argument.]

smp_ops providers do not modify their ops structures, so they should be
made const for robustness. Since currently the MIPS kernel is not mapped
with memory protection, this does not in itself provide any security
benefit, but it still makes sense to make this change.
There are also slight code size efficincies from the structure being
made read-only, saving 128 bytes of kernel text on a
pistachio_defconfig.

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

The MIPS-specific macro CL_SIZE is merely aliasing the macro
COMMAND_LINE_SIZE. Other architectures use the latter; also,
COMMAND_LINE_SIZE is documented in kernel-parameters.txt, so
let's use it, and remove the alias.

CFE is the only supported and used bootloader on the SiByte boards,
the standalone kernel support has been never used outside Broadcom.
Remove it and make the kernel use CFE by default.
