Change ap_mpstart to return non-zero value if any/all APs don't start.

Support SATA on TEGRA210

Thanks to jmcneill for help with this.

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

Use arm_generic_bs_tag instead of armv7_generic_bs_tag and conditionally
define SOC platform support (so we don't try to build 32-bit support into
64-bit kernels).

More XUSB init. A USB3 memory stick seems to work now.

Replace unused mpio driver with a more generic interface for pinmux, and
add Tegra210 pinmux support.

The xusbpad driver is tegra 124 specific so split it out into a separate
driver. Add (not yet working) tegra 210 support to the xusb driver.

Get rid of tegra_chip_id/tegra_chip_name and rely on FDT for this info.

FDT-ize "delay" by having fdt_machdep provide the delay() function and
move the implementations into the platform code.

Enumerate CPUs, GIC, and generic timer using FDT data instead of relying
on hard-coded tables in mainbus.

tegra_dma_bootstrap is no more

Chip detection and MP spinup code for Tegra210

Add Tegra210 chip ID.

Get rid of tegra_cpuinit after scanning fdt and attach the cpufreq support
to the /cpus node. Use regulator API instead of poking directly at the I2C
controller to set voltages.

Get the physical memory layout from the /memory node instead of reading
from the memory controller registers.

Only route USB ports to XHCI controller after the firmware is loaded
successfully. This gives us working USB (via USB2 controllers) until the
tegra-firmware package is installed.
