Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors.  AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested.  Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively

Resolve a couple of conflicts (result of the uimin/uimax changes)

Provide and use kern_vtopdiff in KERN_{VTOPHYS,PHYSTOV}.  A step towards
generic arm.

on evbarm/RPI,RPI2, VERBOSE_INIT_ARM had broken.

XPUTC() of evbarm/rpi/rpi*_start.S uses bcm283[567]_platform_early_putchar() and it requires stack.
fixed to allocate stack when starting from rpi*_start.S and a9_mpsubr.S if needed.

to work XPUTC(), need to define VERBOSE_INIT_ARM and EARLYCONS option.

remove unnecessary code. .Lmmu_init_table is in same section, and also not r8.

Start code now updates a global variable fdt_addr_r to handle differences
in boot protocol (think arm64)

FDTise RapberryPI support. Thanks for jmcneill for a lot of help with this.

The kernel image that the RPI firmware boots is now netbsd.img in the
kernel build directory.

XXX fdtbus_get_reg needs reworking

Check for hypervisor mode in cortex_init and exit if the cpu started
there.
Needed by latest RPI firmware.
--
Fix up bus_space_map for latest RPI firmware which now passes the FB
address in the mailbox properties as a bus address.
--
Update RPI firmware to version after the following commit
commit 224c75602b8bae1a9e942b4f1c7ed3aa8e0f0ec8
Author: popcornmix<popcornmix@gmail.com>
Date:   Tue Dec 8 14:48:57 2015 +0000
--
Deal with kernel builds where virtualisation isn't available
--
Tweak CPUFLAGS to cover all CPUs
--
Fix up bcm283[56] bus_space(4) to really use bus addresses for
peripherals, etc
Simplifies the code in various places and uses the abstraction in
more places. (bcm2835_gpio_subr.c still doesn't)

Move some options into std.rpi
--
Add __HAVE_MM_MD_CACHE_ALIASING
Pull up following revision(s) (requested by skrll in ticket #582):
Fix TPIDRPRW_IS_CURLWP builds.
--
A MULTIPROCESSOR kernel requires TPIDRPRW_IS_CURCPU.
--
Use TPIDRPRW_IS_CURLWP as it's a slight code reduction and performance
improvement.
Initial RPI2 support - it doesn't work yet. The generic timer gets messed
up somehow.
This commit changes the KVA layout of the RPI.
--
Make this compile where gtmr isn't used.
--
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.
--
Appease a KASSERT - will be remove when MULTIPROCESSOR RPI2 is fixed.
--
Add RPI2 to kernels build for both earmv[67].
Use the earmv6 built kernels to create an image that can be used on both
RPI and RPI2
--
Add an RPI2_INSTALL
