Ippo_q8h_v1_2_a33_1024x600, Ippo_q8h_v1_2 and TZX-Q8-713B7 tablet, and the
forfun_q88db_defconfig is identical to q8_a13_tablet_defconfig.

This leaves only the Ippo_q8h_v5 untested with the new generic defconfigs
but there is no reason to assume that it will not work.

ls102xa: Fix reset hang

Since commit 623d96e89aca6("imx: wdog: correct wcr register settings")
issuing a 'reset' command causes the system to hang.

Unlike i.MX and Vybrid, the watchdog controller on LS102x is big-endian.

This means that the watchdog on LS1021 has been working by accident as
it does not use the big-endian accessors in drivers/watchdog/imx_watchdog.c.
Commit 623d96e89aca6("imx: wdog: correct wcr register settings") only
revelead the endianness problem on LS102x.

In order to fix the reset hang, introduce a reset_cpu() implementation that
is specific for ls102x, which accesses the watchdog WCR register in big-endian
format. All that is required to reset LS102x is to clear the SRS bit.

This approach is a temporary workaround to avoid a regression for LS102x
in the 2015.10 release. The proper fix is to make the watchdog driver
endian-aware, so that it can work for i.MX, Vybrid and LS102x.

arndale: Apply Cortex-A15 errata #773022 and #774769

We run 4 Arndale boards in our automated test framework, they have
been running quite happily for quite some time using a Debian Wheezy
userspace.

However when upgrading to a Debian Jessie we started seeing frequent
segmentation faults from gcc when building the kernel, to the extent
that it is unable to successfully build the kernel twice in a row, and
often fails on the first attempt.

Searching around I found https://bugs.launchpad.net/arndale/+bug/1081417
which pointed towards http://www.spinics.net/lists/kvm-arm/msg03723.html
and CPU Errata 773022 and 774769.

This errata needs to be applied to all processors in an SMP system,
meaning that the usual strategy of applying them in
arch/arm/cpu/armv7/start.S is not appropriate (since that applies to
the boot processor only). Instead we apply these errata in the secure
monitor which is code that is traversed by all processors as they are
brought up.

The net affect on Arndale is that ACTLR changes from 0x40 to
0x2000042. I ran 17 kernel compile iterations overnight with no
segfaults.

Runtime testing was done on our v2014.10 based branch and forward
ported (with only minimal and trivial contextual conflicts) to current
master, where it has been build tested only.

I suppose in theory these errata apply to any Exynos5250 based boards,
but Arndale is the only one I have access to and I have therefore
chosen to be conservative and only apply it there.

Also, reorder CONFIG_ARM_ERRATA_794072 in README to make the list
