Subject: [PATCH 2/8] MIPS: BCM63XX: Add flash type detection
On BCM6358 and BCM6368 the attached flash type is exposed through a
bootstrapping register. Use it for auto detecting the flash type on
those and default to parallel flash for earlier SoCs.

Subject: [PATCH 3/8] MIPS: BCM63XX: Use the Chip ID register for identifying the SoC
Newer BCM63XX SoCs use virtually the same cpu ID. But since they all have
the Chip ID register at the same location, we can use that to identify
the SoC we are running on.
Newer BCM63XX SoCs use virtually the same CPU ID, differing only in the
revision bits. But since they all have the Chip ID register at the same
location, we can use that to identify the SoC we are running on.

This includes CPU speed, memory size detection and working UART, but
lacking the appropriate drivers, no support for attached flash.

Register devices as an arch initcall so that the fallback sprom gets
installed in the same phase as the pci bus gets registered.

Subject: [PATCH 04/59] Revert "MIPS: BCM63XX: Call board_register_device from device_initcall()"
This commit causes a race between PCI scan and SSB fallback SPROM handler
registration, causing the wifi to not work on slower systems. The only
subsystem touched from board_register_device is platform device
registration, which should be safe as an arch init call.
This reverts commit d64ed7ada2f689d2c62af1892ca55e47d3653e36.

Subject: [PATCH 2/2] MIPS: BCM63XX: explicitly register the PCI bus
Instead of setting a global variable toggling the PCI registration,
register it in the device_register phase after setting the fallback
sprom to ensure there cannot be a race between them.
