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

This approach is a temporary workaround to avoid a regression for LS102x

However when upgrading to a Debian Jessie we started seeing frequent

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

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,

Fix this by always keeping empty files clusterless as specified by

calls, which removes some cases of set_cluster() being called with a
size of zero.
set_cluster() was using a temporary buffer without enforcing its
alignment for DMA and cache. Moreover, it did not check the alignment of
the passed buffer, which can come directly from applicative code or from
the user.
This could cause random data corruption, which has been observed on
i.MX25 writing to an SD card.
Fix this by only passing ARCH_DMA_MINALIGN-aligned buffers to
disk_write(), which requires the introduction of a buffer bouncing
mechanism for the misaligned buffers passed to set_cluster().
By the way, improve the handling of the corresponding return values from
disk_write():
- print them with debug() in case of error,
- consider that there is an error is disk_write() returns a smaller
block count than the requested one, not only if its return value is
negative.
After this change, set_cluster() and get_cluster() are almost
symmetrical.

vexpress64: juno: use /dev/sda2
This patch changes the default "root=" parameter to "/dev/sda2".
Many linux based distros use /dev/sda1 for their boot partition; this is
often not a rootfs that can be used by the "root=" parameter.
Linaro images use /dev/sda1 as a boot partition, although this of a
different nature to a distro image. Linaro uses /dev/sda2 for the rootfs
partition.

vexpress64: juno: add alternate kernel and device tree filenames
The latest Juno firmware stores the files in NOR flash as "norkern" for
kernel binary, "board.dtb" for the device tree binary.
The "old" firmware used the name "Image" for the kernel binary and
"juno" for the device tree binary.
Rather than just change the default U-Boot configuration to use the new
names, breaking users with the old firmware, attempt to load the default
filename first. If that fails, attempt to load the alternate filename.
I've echo'd that we are loading the alternate file to counter the
output from "afs load" shown if the first load attempt fails. For
example, I see output like this on my Juno board when it's configured
the with the "old" firmware:
image "norkern" not found in flash
Loading Image instead of norkern
loaded region 0 from 08500000 to 80000000, 00AB6318 bytes
image "board.dtb" not found in flash
Loading juno instead of board.dtb
loaded region 0 from 0A000000 to 83000000, 00003188 bytes

vexpress64: fvp dram: add DRAM configuration
Create an additional FVP configuration to boot images pre-loaded into
DRAM.
Sometimes it's preferential to boot the model by loading the files
directly into DRAM via model parameters, rather than using
SemiHosting.
An example of model parmaters that are used to pre-load the files
into DRAM:
--data cluster0.cpu0=Image@0x80080000 \
--data cluster0.cpu0=fvp-base-gicv2-psci.dtb@0x83000000 \
