Ignoring the last page when ddr size is 128M. Cached accesses to last
page is causing the processor to prefetch using address above 128M
stepping out of the ddr address space.

The previous patch 4a86f2d27733f610e642649aca3e82e86fca9e22 (lmo) rsp.
84a6fcb3 (kernel.org) was wrong.

The BCM47xx architecture maps the ram into a 128MB address space. It
will be spaced there as often as goes into the 128MB. Detection tries to
find the position where the same memory is found. When reading beyond
128MB the processor will throw an exception. If 128MB RAM is installed,
it will not find a memory alias because it tries to read beyond the 128MB
border. Now it just assumes 128MB installed ram if it can not find an
alias.

Recent git versions now warn about those and they've always been a bit of
an annoyance.

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.

Since commit 22242681 ("MIPS: Extend
COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this
size will cause an build failure with default CONFIG_FRAME_WARN settings.

Although current users of such array variables are all early bootstrap
code and not likely to cause real stack overflow (thread_info corruption),
it is preferable to  to declare these arrays static with __initdata.

Add CFE support to the BCM47XX code.  That includes querying CFE environment
variables as well as using CFE to print messages before the serial port is
initialized (early printk).

Note that the BCM4710 does not support the wait instruction, this
is not a mistake in the code.
    
It originally comes from the OpenWrt patches.

This is to break the code of people who think they are supposed to scribble
into the pci device structure - it's off limits.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
