MIPS: BMIPS: support booting from physical CPU other than 0
...
BMIPS43xx CPUs have two hardware threads, and on some SoCs such as 3368,
the bootloader has configured the system to boot from TP1 instead of the
more usual TP0. Create the physical to logical CPU mapping to cope with
that, do not remap the software interrupts to be cross CPUs such that we
do not have to do use the logical CPU mapping further down the code, and
finally, reset the slave TP1 only if booted from TP0.

MIPS: Only set cpu_has_mmips if SYS_SUPPORTS_MICROMIPS
...
As Jonas Gorske said in his patch:
Disable cpu_has_mmips for everything but SEAD3 and MALTA. Most of
these platforms are from before the micromips introduction, so they
are very unlikely to implement it.
Reduces an -Os compiled, uncompressed kernel image by 8KiB for
BCM63XX.
This patch taks a different approach than his, we gate the runtime
test for microMIPS by the config symbol SYS_SUPPORTS_MICROMIPS.

MIPS: Get rid of MIPS I flag and test macros.
...
MIPS I is the ancestor of all MIPS ISA and architecture variants. Anything
ever build in the MIPS empire is either MIPS I or at least contains MIPS I.
If it's running Linux, that is.
So there is little point in having cpu_has_mips_1 because it will always
evaluate as true - though usually only at runtime. Thus there is no
point in having the MIPS_CPU_ISA_I ISA flag, so get rid of it.
Little complication: traps.c was using a test for a pure MIPS I ISA as
a test for an R3000-style cp0. To deal with that, use a check for
cpu_has_3kex or cpu_has_4kex instead.
cpu_has_3kex is a new macro. At the moment its default implementation is
!cpu_has_4kex but this may eventually change if Linux is ever going to
support the oddball MIPS processors R6000 and R8000 so users of either
of these macros should not make any assumptions.

tty/8250_dw: Add support for OCTEON UARTS.
...
A few differences needed by OCTEON:
o These are DWC UARTS, but have USR at a different offset.
o Internal SoC buses require reading back from registers to maintain
write ordering.
o 8250 on OCTEON appears with 64-bit wide registers, so when using
readb/writeb in big endian mode we have to adjust the membase to hit
the proper part of the register.
o No UCV register, so we hard code some properties.
Because OCTEON doesn't have a UCV register, I change where
dw8250_setup_port(), which reads the UCV, is called by pushing it in
to the OF and ACPI probe functions, and move unchanged
dw8250_setup_port() earlier in the file.

MIPS: BCM63XX: add support for BCM3368 Cable Modem
...
The Broadcom BCM3368 Cable Modem SoC is extremely similar to the
existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort
in the existing code base is required to get it supported. This patch adds
support for the following on-chip peripherals:
- two UARTS
- GPIO
- Ethernet
- SPI
- PCI
- NOR Flash
The most noticeable difference with 3368 is that it has its peripheral
register at 0xfff8_0000 we check that separately in ioremap.h. Since
3368 is identical to 6358 for its clock and reset bits, we use them
verbatim.
