Lots of changes specific to one of the SoC families. Some that
stick out are:
* mach-qcom gains new features, most importantly SMP support for
the newer chips (Stephen Boyd, Rohit Vaswani)
* mvebu gains support for three new SoCs: Armada 375, 380 and 385
(Thomas Petazzoni and Free-electrons team)
* SMP support for Rockchips (Heiko Stübner)
* Lots of i.MX changes (Shawn Guo)
* Added support for BCM5301x SoC (Hauke Mehrtens)
* Multiplatform support for Marvell Kirkwood and Dove
(Andrew Lunn and Sebastian Hesselbarth doing the final part
of a long journey)
* Unify davinci platforms and remove obsolete ones (Sekhar Nori,

CLPS711X CPUs have 128 bytes of on-chip Boot ROM with an
instruction sequence that configure UART1 to receive up to
2 Kbytes of serial data which is then placed in the on-chip
SRAM. Once the download is complete, the program counter
jumps to SRAM to begin executed the downloaded data.
The purpose of this mode is to allow the downloaded code to
facilitate programming of FLASH or other ROM device. Selection
of the internal Boot ROM is accomplished at power-on-reset time.
No reason to keep this special (develop only) mode in the kernel.
This patch removes EP72XX_ROM_BOOT kernel symbol.

While <mach/timex.h> isn't used for multi-platform builds since long it
still is for "normal" builds. As the previous patches fix all sites to

While at it there are no users of CLOCK_TICK_RATE any more, so also drop

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite. Remove arm_machine_restart() as this function
no longer does anything useful.
For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions. As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart. Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.
This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.

Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use. Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.
This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.
