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

This could cause random data corruption, which has been observed on

vexpress64: juno: add alternate kernel and device tree filenames
The latest Juno firmware stores the files in NOR flash as "norkern" for

Rather than just change the default U-Boot configuration to use the new

Currently when driver model starts up it finds the root uclass and the

But this is not useful. The root node is not a real hardware device so
cannot require any particular pinmux settings. Also it means that the
memory leak tests fails, since they end up freeing more memory than
they allocate: the marker it set after the root device and pinctrl
uclass are allocated, and later once the pinctrl uclass is freed the memory
used by driver model is less than when the marker was set.
If a platform needs 'core' pin mulitplex settings it can do this with
a driver that is probed on start-up. It would be an abuse of the root node
to use this for pinctrl.

rockchip: Reconfigure the malloc based to point to system memory
When malloc_base initially gets setup in the SPL it is based on the
current (early) stack pointer, which for rockchip is pointing into SRAM.
This means simple memory allocations happen in SRAM space, which is
somewhat unfortunate. Specifically a bounce buffer for the mmc allocated
in SRAM space seems to cause the mmc engine to stall/fail causing
timeouts and a failure to load the main u-boot image.
To resolve this, reconfigure the malloc_base to start at the relocated
stack pointer after DRAM has been setup.
For reference, things did work fine on rockchip before
596380db was
merged to fix memalign_simple due to a combination of rockchip SDRAM
starting at address 0 and the dw_mmc driver not checking errors from
bounce_buffer_start. As a result, when a bounce buffer needed to be
allocated mem_align simple would fail and return NULL. The mmc driver
ignored the error and happily continued with the bounce buffer address
being set to 0, which just happened to work fine..

After rework of lib/fdtdec.c by:

02464e3 fdt: add new fdt address parsing functions
the function fdtdec_get_addr() doesn't work as previous,
because the implementation assumes that properties '#address-cells'

The new API introduced fdtdec_get_addr_size_auto_parent() for the 'reg'
property parsing, but the implementation assumes, that #size-cells
can't be less than 1.
This causes that the following children's 'reg' property can't be reached:
parent@0x0 {
#address-cells = <1>;
#size-cells = <0>;
children@0x100 {
reg = < 0x100 >;
};
};
Change the condition value from '1' to '0', which allows parsing property
with at least zero #size-cells, fixes the issue.

fdt: fix fdtdec_get_addr_size not to require any size cells
fdtdec_get_addr_size() may be used in two cases:
a) With sizep supplied, in which case both an address and a size are
parsed from DT. In this case, the DT property must be large enough to
contain both values.
b) With sizep NULL, in which case only an address is parsed from DT.
In this case, the DT property only need be large enough to contain this
address value. Commit
02464e386bb5 "fdt: add new fdt address parsing
functions" broke this relaxed checking, and required the DT property to
contain both an address and a size value in all cases.
Fix fdtdec_get_addr_size() to vary ns based on whether the size value
is being parsed from the DT or not. This is safe since the function only
parses the first entry in the property, so the overall value of (na + ns)
need not be accurate, since it is never used to step through the property
data to find other entries. Besides, this fixed behaviour essentially
matches the original behaviour before the patch this patch fixes. (The
original code validated that the property was exactly the length of
either na or (na + ns), whereas the current code only validates that the
property is at least that long. For non-failure cases, the two behaviours
are identical).

set_direction() mean, and similarly for the return values from the
respective get_*(), define named constants for these values.
Disassembly shows no diff in the generated code, except that the
order of the code in the branches of tegra_gpio_get_function() gets
modified without affecting behaviour.

ARM: tegra: expand all SPL sizes to be consistent
The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:
arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes
(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

ARM: tegra: don't enable GPIOs until direction is set
Tegra's GPIO driver currently enables pins as GPIO as soon as they're
requested. This is not safe, since the desired direction and output value
are not yet known. This could cause a glitch on the output pins between
gpio_request() and gpio_direction_*(), depending on what values happen to
be in the GPIO controller's in/out and out-value registers vs. the final
desired configuration.
To solve this, defer enabling pins as GPIOs until some gpio_direction_*()
is invoked, and the desired configuration is explicitly programmed.
In theory this change could cause regressions, if code exists that claims
a GPIO, never explicitly sets a direction, and then gets/sets the GPIO
value based on that assumption. However, I've read through all the Tegra-
related board files and device drivers that touch GPIOs and I do not see
such buggy code anywhere.

ARM: tegra: fix GPIO init table programming
Tegra's gpio_config_table() currently uses common GPIO APIs. These used
to work without requesting the GPIO, but since commit
2fccd2d96bad "tegra:
Convert tegra GPIO driver to use driver model" no longer do so. This
prevents any of the GPIO initialization table from being applied to HW.
Fix gpio_config_table() to directly program the HW to solve this.

I2C: mxc_i2c: make I2C1 and I2C2 optional
The driver assumed that I2C1 and I2C2 were always enabled,
and if they were not, then an asynchronous abort was (silently)
raised, to be caught much later on in the Linux kernel.
Fix this by making I2C1 and I2C2 optional just like I2C3 and I2C4
are.
To make the change binary-invariant, declare I2C1 and I2C2 in
every include/configs/ file which defines CONFIG_SYS_I2C_MXC.
Also, while updating README about CONFIG_SYS_I2C_MXC_I2C1 and
CONFIG_SYS_I2C_MXC_I2C2, add missing descriptions for I2C4 speed
(CONFIG_SYS_MXC_I2C4_SPEED) and slave (CONFIG_SYS_MXC_I2C4_SLAVE)
