Retire arch/evbarm/beagle.

A few more kernel configs go away:

- OMAP5EVM and PANDABOARD likely never worked to begin with.
- N900 and VTC100 are TI AM335x based, which is supported by GENERIC.

Provide and use a sev() macro for the sev instruction.

While here use the correct barrier to ensure completion of memory accesses

Retire arm_[di]sb in favour of the isb() and dsb(sy) macro invocations.

Collapse all CPU_CORTEXA<n> options into CPU_CORTEX and do runtime

Various updates and improvements to cpu start up on arm/aarch64

- start sharing more code around the AP startup messaging.
- call arm_cpu_topology_set early so that ci_core_id is available for
  drivers, e.g. bcm2835_intr.c
- both arm and aarch64 now have
  - a static cpu_info_store array
  - the same arm_cpu_{hatched,mbox}

Convert remaining armv7 kernels to generic start and remove a bunch of
code including a9_mpsubr.S.

Thanks to Lwazi Dube for testing PANDABOARD and BEAGLEBONE.

Sync with head

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

Rebase.

Conditionalize more stuff on TI_AM335X so BEAGLEBONEXM kernel
builds succeed.

am335x: expect the board code to provide a set_mpu_volt() function,
to change the MPU code voltage. When changing MPU frequency also request
a voltage change. provide frequency/voltage tables for the "blank" revision
and de A revision, based on documents from www.ti.com (this means
it's not possible anymore to request a beaglebone white to run at 1Ghz,
but this was not working anyway).
beagle_machdep.c: callback to the tps65217pmic to change the MPU voltage.

Tested on beaglebone, from 275 to 720Mhz, and on beaglebone black from
300 to 1000Mhz.

Allow tifb to be the console when bootargs contains "console=fb".

Actually, only copy the uboot args if they are within the amount of ram we
mapped.  If they aren't we'd fault trying to access them.  It's too early
to grab a VA to map them so we just punt for now. XXX

sanity check uboot_args is within 512MB (not 256MB) for beaglebone black).

am335x_cpu_clk is now am335x_sys_clk and am335x_cpu_clk and they are now
in <arm/omap>.

Add code to make eMMC 8-bit (disabled) since it still needs code in omap3_sdhc
to actually enable 8-bit mode.

more OMAP5 workarounds.
u-boot doesn't initialize the generic timer on the omap5430 evm properly.
so check to see if it's OK, and if not, initialize omap5 registers properly.
Pass the timer freq via properties to the armgtmr since we can't write the
cnt_frq cp15 register (which can be written in secure mode).

Add OMAP5 reset code.

Add PL310 L2CC init for OMAP4.
Use OMAP_[345]XXX
Add OMAP4 hooks in beagle_device_register

Don't hardcode beagle_putchar com values.

adapt am335x memprobe so it can be used by omap4/omap5.
Fill in the reference clock (omap_sys_clk) when determining speed.
Make sure memory controller are mapped.
Make sure to map console PA in bootstrap page table.

Now that VBAR support is present, switch to ARM_VECTORS_LOW.

Make sure there is enough KVA to map all of memory if
__HAVE_MM_MD_DIRECT_MAPPED_PHYS is defined.

Fix typo.

Fix probing error on BBONE due to wrong value being used in u-boot to
program the DDR controller.

for the TI AM335x, use the control_status register in the control module
to obtain the base frequency instead of assuming it's always 24MHz.

Map EMIF0 for TIAM335X and use to probe memory size.

include com.h before testing NCOM

Set the framebuffer as the default console when no serial port is configured.
This was tested on a Nokia N900 with the N900 kernel. The BEAGLEBOARD kernel

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled.  So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks().  Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown().  No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown().  I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that.  Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

Adapt to the 3530 address spaces.

Initial BEAGLEBOARD support.  Compile tested only so far.
