0a271c2a34 mips/irq: prepare for drivers/irqchip/irqchip.h removal 
The IRQCHIP_DECLARE macro migrated to 'include/linux/irqchip.h'.

See commit 91e20b5040c67c51aad88cf87db4305c5bd7f79d
("irqchip: Move IRQCHIP_DECLARE macro to include/linux/irqchip.h").

This patch removes inclusions of private header 'drivers/irqchip/irqchip.h'and
replaces them with the inclusion of 'include/linux/irqchip.h'.

ca668a2da4 MIPS: BMIPS: Accept UHI interface for passing a dtb 
Detect and use passed dtb address using the UHI interface. This allows for
booting with a vmlinux.bin appended dtb instead of using a built-in one.

380e4270f5 MIPS: BMIPS: Add support for Broadcom BCM97435SVMB 
Add a DTS file and Kconfig entry for the BCM97435SVMB evaluation board
using bcm7435.dtsi as an example.

The current code needs some tweaking to allow us to use the
dual-threaded dual BMIPS5200 CPUs, so for now we limit ourselves to
allowing just a single CPU to be booted.

8a5f1efbb1 MIPS: BMIPS: restrict DTB selection to BMIPS_GENERIC 
Since we are always sourcing arch/mips/bmips/Kconfig and there is no
dependency on BMIPS_GENERIC, we will offer building BMIPS-related DTBs
while this is not relevant for the other MIPS platforms.

8945e37e10 MIPS: BMIPS: Add DTS files for several platforms 
Most of the supported chips use legacy (non-DT) bootloaders, so they will
need to select an appropriate builtin DTB at compile time until the
bootloader is updated.  Provide suitable DTS files, and a means to compile
one of them into the kernel image.

e5a6fcc058 MIPS: BMIPS: Delete the irqchip driver from irq.c 
BCM3384/BCM63xx can use the common drivers/irqchip/irq-bcm7120-l2.c for
this purpose; BCM7xxx will use drivers/irqchip/irq-bcm7038-l1.c.  We no
longer need this code under arch/mips.

to reflect this.
