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

Revert "powerpc: ppc4xx: remove lwmon5 support"
This reverts commit
8fe11b8901a31d11990488c82bc23612589d57be.
I'll add support to lwmon5 in the next patch and will remove
support for the broken lcd4_lwmon5 as well.

fs/fat/fat_write: Fix management of empty files
Overwriting an empty file not created by U-Boot did not work, and it
could even corrupt the FAT. Moreover, creating empty files or emptying
existing files allocated a cluster, which is not standard.
Fix this by always keeping empty files clusterless as specified by
Microsoft (the start cluster must be set to 0 in the directory entry in
that case), and by supporting overwriting such files.

fs/fat/fat_write: Fix curclust/newclust mix-up
curclust was used instead of newclust in the debug() calls and in one

fs/fat/fat_write: Merge calls to set_cluster()
set_contents() had uselessly split calls to set_cluster(). Merge these
calls, which removes some cases of set_cluster() being called with a
size of zero.

fs/fat/fat_write: Fix buffer alignments
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
