This revision does the following renames:
CPU_MIPS24KC -> CPU_MIPS24K
CPU_MIPS74KC -> CPU_MIPS74K
CPU_MIPS1004KC -> CPU_MIPS1004K
It also adds the following new CPU_MIPSxxx options:
CPU_MIPS24KE, CPU_MIPS34K, CPU_MIPS1074K, CPU_INTERAPTIV, CPU_PROAPTIV
CPU_MIPSxxxxKC is limiting and possibly misleading as it implies the
MIPSxxxxK CPU has no FPU.
It would be better if the CPUs are named after their standard functionalities
only and the presence or absence of FPU can then be controlled via the
CPU_HAVEFPU option.
I will send out another dependent revision that moves MIPS 32 r2 and r3
CPUs to use the EHB instruction for clearing hazards instead of NOP/SSNOP.

MD_ROOT_SIZE and embed_mfs.sh were basically retired as part of
https://reviews.freebsd.org/D2903 .
However, when building a kernel with 'options MD_ROOT_SIZE' specified, this
results in a non-working MFS, as within sys/dev/md/md.c we fall within the
wrong # ifdef.
This patch implements the following:
* Allow kernels to be built without the MD_ROOT_SIZE option, which results
in a kernel built as per D2903.
* Allow kernels to be built with the MD_ROOT_SIZE option, which results
in a kernel built similarly to the pre-D2903 way, with the following
differences:
* The MFS is now put in a separate section within the kernel (oldmfs,
so it differs from the mfs section introduced by D2903).
* embed_mfs.sh is changed, so it looks up the oldmfs section within the
kernel, gets its size and offset, sees if the MFS will fit within the
allocated oldmfs section and only if all is well does a dd of the MFS
image into the kernel.

Allows for using hardware watchpoints for 1, 2, 4, 8 byte long addresses.
The default configuration of watchpoint is RW but code allows to select
RO or WO and X.
Since debugging registers are per-CPU (CP14) the watchpoint is set on
the CPU that was lucky (or not) to enter DDB.
HW breakpoints are used to perform single step in KDB.
When HW breakpoint is enabled all watchpoints are temporary disabled
to avoid recursive abort on both watchpoint and breakpoint.
In case of branch, the breakpoint is set to both - next instruction
and possible branch address. This requires at least 2 breakpoints
supported in the CPU however this is a must for ARMv6/v7 CPUs.

support frameworks(i.e. reset/regulators/phy/tsensors/fuses...).
The clock framework significantly simplifies handling of complex clock
structures found in modern SoCs. It provides the unified consumers
interface, holds and manages actual clock topology, frequency and gating.
It's tested on three different ARM boards (Nvidia Tegra TK1, Inforce 6410 and
Odroid XU2) and on one MIPS board (Creator Ci20) by kan@.
The framework is still far from perfect and probably doesn't have stable
interface yet, but we want to start testing it on more real boards and
different architectures.

This fixes .depend.genassym.o not being included. genassym.o depends on
all of the system headers and when rebuilt regenerates assym.s which
lists offsets for critial .S files to utilize. By having a struct in a
system header change its offsets and not have generassym.o be rebuilt,
this would lead to panics.
The flaw in the initial commit was seeing ${OBJS} in ${SYSTEM_OBJS} and
assuming it had all of ${SRCS} in it. This is not the case though. The
older mkdep code splits out all of the various SRC lists for generating
the .depend file. It also includes ${GEN_CFILES}, which had genassym.c
and was the only significant file lacking from ${SYSTEM_OBJS} upon inspection,
since it is not linked in. Rather than duplicate the likely
soon-to-be-removed mkdep lists, just add genassym.o to the DEPENDOBJS
list. Using ${SRCS} as bsd.dep.mk does would be nice but there are many
files in the build that are only added to ${OBJS} and not ${SRCS}, such
as bf_enc.o derived from bf_enc.S for i386.
