This code makes the irqs used by the EIU loadable from the DT. Additionally we
add a helper that allows the pinctrl layer to map external irqs to real irq
numbers.

Very ancient out-of-tree KDB versions were using BRK_KDB code but it's
unused in modern kernels since a long time. Delete it.
The microMIPS encoding only reserves 4 bits for a trap code so it's time
for further weedkilling.

The BRK_BUG value is used in the BUG and __BUG_ON inline macros. For
standard MIPS cores the code in the 'tne' instruction is 10-bits long.
In microMIPS, the 'tne' instruction is recoded and the code can only be
4-bits long. We change the value to 12 instead of 512 so that both classic
and microMIPS kernels build.
[ralf@linux-mips.org: Many of the break codes starting from 0 are used
across many MIPS UNIX variants. Codes starting from 512 are operating
system specific additions. 1023 again is also used by other operating
systems]

Display the MIPS ISA version release in the /proc/cpuinfo file.
[ralf@linux-mips.org: Add support for MIPS I ... IV legacy architecture
revisions. Also differenciate between MIPS32 and MIPS64 versions instead
of lumping them together as just r1 and r2.
Note to application programmers: this indicates the CPU's ISA level
It does not imply the current execution environment does support it. For
example an O32 application seeing "mips64r2" would still be restricted by
by the execution environment to 32-bit - but the kernel could run mips64r2
code. The same for a 32-bit kernel running on a 64-bit processor. This
field doesn't include ASEs or optional architecture modules nor other
detailed flags such as the availability of an FPU.]

An SoC normally do not define path variables for board_rev and
board_type and the Broadcom SDK also uses the nvram values without a
prefix in such cases. Do the same to fill these sprom attributes from
nvram and do not leave them empty, because brcmsmac do not like this.

All the boot loaders I have seen are booting the kernel in raw mode by
default. CFE seems to support elf kernel images too, but the default
case is raw for the devices I know of. Select this option to make the
kernel boot on most of the devices with the default options.

The old code just worked for nvram with a size of 0x8000 bytes. This
patch adds support for reading nvram from partitions of 0xF000 and
0x10000 bytes.
There is just 32KB space for the nvram, but most devices do not use the
full size and this code reads the first 32KB in that case and prints a
warning.
