728b01dfee Before spinning up the secondary cpus flush the dcache otherwise the 
dcache invalidate in cortex_mpstart makes bad things happen.

I have no idea why.

config otherwise.

5b9b796bff Spin up the non-boot CPUs, but don't allow cpu_boot_secondary_processors 
to see them for now.

RPI2 nows works well with only the boot cpu.

1f9df33256 Initial RPI2 support - it doesn't work yet. The generic timer gets messed

This commit changes the KVA layout of the RPI.

d415dbe367 Newer Raspberry Pi firmware has changed the framebuffer from BGR to RGB. 
The method we use to set the pixel order (vcprop set pixel order) does
not seem to work, nor does querying the pixel order (vcprop get pixel order).

The firmware passes this information to the kernel by adding a
"bcm2708_fb.fbswap" kernel cmdline arg. 0=BGR, 1=RGB. If the parameter is
absent, assume we are running on old firmware and use BGR mode.

d06bdb36a4 Enabling alignment faults and unaligned access at the same time makes 
the former win. LLVM is more aggressive than GCC about using unaligned
access, so it would crash during pmap_init.

4daade7385 Add a new installer image for Raspberry PI to evbarm 
Includes the following major changes:

1) Add new configmenu item to sysinst to allow creation of users at
post-install time.
2) Add an sshramdisk type to evbarm, which is a ramdisk with sshd
enabled, allowing users to install on a headless PI by sshing to the
device with the account "sysinst" password "netbsd" to begin the
installation. (Note, neither the account, nor the ssh setup are copied to
the finalized installation image)
3) Change mkimage to build a boot-only image, without the root filesystems.

Much of the sshramdisk code could be reused on other ports easily.
