Update the L2 AUX CTRL settings for the SoCFPGA.
Enabling D and I prefetch bits helps improve SDRAM performance on the

Also, we need to enable bit 22 of the L2. By not having bit 22 set in the
PL310 Auxiliary Control register (shared attribute override enable) has the
side effect of transforming Normal Shared Non-cacheable reads into Cacheable
no-allocate reads.
Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer

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.

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
numerically sorted.

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..

Currently booting on A38x is broken. As the current code tries to detect
the SoC family to disable the MMU for the A38x at runtime. But before the
internal registers are switched to the new location (0xf100.0000), this
runtime detection does not work. As all macros / defines are already
assigned to the new location at 0xf100.0000. But the registers are sill
mapped to the default location at 0xd000.0000.
This patch now makes sure, no such runtime detection is used before
the internal registers are configured to the new location. After this,
the remaining cache cleanup is executed.

The 7" Q8 tablet enclosure is used for a ton of slightly different cheap
chinese tablets. There are some differences in which accelerometer /
wifi is used, but other then that these are all the same from a u-boot /
kernel pov.
When we get to adding accelerometer support the plan is to add some kind
of autodetection and mangle the dt accordingly (likely using the new quirks
mechanism).
For now this is a non issue as we do not yet have accelerometer
support, and in the future, some sort of auto-detect is the way to go
as we cannot expect users to exactly know what is inside their tablet.
The dts[i] files this commit adds are identical to the ones submitted
to the upstream kernel.

This patch extends the misc_init_r() function on sunxi boards
to test for the presence of a suitable "sunxi" SPL header. If
found, and the loader ("fel" utility) provided a non-zero value
for the boot.scr address, then the corresponding environment
variable fel_scriptaddr gets set.
misc_init_r() also sets (or clears) the "fel_booted" variable depending
on the active boot device, using the same logic as spl_boot_device().
The goal is to provide sufficient information (within the U-Boot
environment) to make intelligent decisions on how to continue the boot
process, allowing specific customizations for the "FEL boot" case.

This patch follows up on a discussion of ways to improve support
for the sunxi FEL ("USB boot") mechanism, especially with regard
to boot scripts, see:
https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ
The idea is to convert the (currently unused) "pad" bytes in the
SPL header into an area where data can be passed to U-Boot. To
do this safely, we have to make sure that we're actually using
our "sunxi" flavor of the SPL, and not the Allwinner boot0.
The modified mksunxiboot introduces a special signature to the
SPL header in place of the "pub_head_size" field. This can be
used to reliably distinguish between compatible versions of sunxi
SPL and anything else (older variants or Allwinner's boot0).

Use DM for the pl01x serial driver on hikey. Also allow UART0 or
UART3 to be chosen via Kconfig.
By default we now output to UART3 as the latest version of ATF outputs
to this UART. Also UART3 comes out on the LS connector, as opposed to
UART0 which goes to a unpopulated header.
As part of this change we also enable CONFIG_BOARD_EARLY_INIT_F and
call the pinmux configuration code for the UART. Before we were
relying on ATF having already configured the pin configuration.
NB: Upstream Linux kernel doesn't yet support UART3, so serial console

Before this commit, the Kconfig menu in mach-uniphier only allowed us
to choose one SoC to be compiled. Each SoC has its own defconfig file
for the build-test coverage. Consequently, some defconfig files are
duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and
CONFIG_{SOC_NAME}=y.
Now, most of board-specific parameters have been moved to device trees,
so it makes sense to include init code of multiple SoCs into a single
image as long as the SoCs have similar architecture. In fact, some
SoCs of UniPhier family are very similar:
- PH1-LD4 and PH1-sLD8
- PH1-LD6b and ProXstream2 (will be added in the upcoming commit)
This commit will be helpful to merge some defconfig files for better

Currently, IECTRL is enabled after pin-mux settings for the low-level
debugging for PH1-LD4 and PH1-sLD8. While IECTRL is disabled, input
signals are pulled-down, i.e. glitch signal (Low to High transition)
problem occurs if pin-mux is set up first. As a result, one invalid
character is input to the UART block and the auto-boot counting is
terminated immediately.
The correct initialization procedure is:
[1] Enable IECTRL (if IECTRL exists for the pins)
[2] Set up pin-muxing
[3] Deassert the reset of the hardware block
Currently, the low-level debugging is working for PH1-sLD3 and
PH1-Pro4, but just in case, follow the sequence for all the SoCs.

AFAIK, for all PLLs on all Tegra SoCs, the primary PLL output frequency
is (input * m) / (n * p). However, PLLP's primary output (pllP_out0) on
T210 is the VCO output, and divp is not applied. pllP_out2 does have divp
applied. All other pllP_outN are divided down from pllP_out0. We only
support pllP_out0 in U-Boot at the time of writing.
Fix clock_get_rate() to handle this special case.
This corrects the returned rate for PLLP to be 408MHz rather than 204MHz.
In turn, this causes high enough dividers to be calculated for the various
peripheral clocks that feed off of PLLP. Without this, some peripherals
failed to operate correctly. For instance, one of my SD cards worked
perfectly but an older (presumably slower) card could not be read.
Note that prior to commit 722e000ccd "Tegra: PLL: use per-SoC pllinfo
table instead of PLL_DIVM/N/P, etc.", the calculated PLL frequency was
816MHz since the wrong values were being extracted from the PLLP divider
register. This caused overly large peripheral dividers to be calculated,
which while wrong, didn't cause any correctness issues; things simply ran
slower than they could.

>From source code comments:
"x0: 0 flush & invalidate, 1 invalidate only"
Current value 0xffff can make invalidate work, since we only judge whether
input value is 0 or not, see following code:
"
tbz w1, #0, 1f
dc isw, x9
b 2f
1: dc cisw, x9 /* clean & invalidate by set/way */
2: subs x6, x6, #1 /* decrement the way */
"
Later we may add "2 clean only" support. So following the comments,
correct value from 0xffff to 1.

The current simplify lpc32xx gpio driver implementation assume a
maximum of 32 GPIO per port; there are a total of 22 GPI, 24 GPO
and 6 GPIO to managed on port 3.
Update the driver to fix the following:
1) When requesting GPI_xx and GPO_xx on port 3 (xx is the same number)
the second call to "gpio_request" will return -EBUSY.
2) The status of GPO_xx pin report the status of the
corresponding GPI_xx pin when using the "gpio status" command.
3) The gpio driver may setup the direction register for the wrong
gpio when calling "gpio_direction_input" (GPI_xx) or
"gpio_direction_output" (GPO_xx) on port 3; the call to the
direction is require to use the "gpio status" command.
The following change were done in the driver:
1) port3 GPI are cache in a separate 32 bits in the array.
2) port3 direction register written only for GPIO pins.
3) port3 GPO & GPIO (as output) are read using "p3_outp_state".
4) LPC32XX_GPI_P3_GRP updated to match the change.

This commits adds a generic support for q8 formfactor a13 based tablets.
These tablets ship in many variants, with the difference mainly being the
touchscreen controller / accelerometer / wifi chip used.
The wifi is USB based, and thus not listed in devicetree.
ATM the kernel does not support the touchscreen / accelerometer on these
devices. In the future we may need multiple configs with different
CONFIG_DEFAULT_DEVICE_TREE settings, this depends on how we solve the
hw differences on the kernel side.
For now this will suffice.

If we convert to use driver model pci on quark, we will encounter
some chicken and egg problems like below:
- To enable PCIe root ports, we need program some registers on the
message bus via pci bus. With driver model, the first time to
access pci bus, the pci enumeration process will be triggered.
But without first enabling PCIe root ports, pci enumeration
just hangs when scanning PCIe root ports.
- Similar situation happens when trying to access GPIO from the
PCIe enabling codes, as GPIO requires its block base address
to be assigned via a pci configuration register in the bridge.
To avoid such dilemma, replace all pci calls in the quark codes
to use the local version which does not go through driver model.

Intel Quark SoC has a low end x86 processor with only 400MHz
frequency. Currently it takes about 15 seconds for U-Boot to
boot to shell and the most time consuming part is with MRC,
which is about 12 seconds. MRC programs lots of registers on
the SoC internal message bus indirectly accessed via pci bus.
To speed up the boot, create an optimized version of pci config
read/write dword routines which directly operate on PCI I/O ports.
These two routines are inlined to provide better performance too.
Now it only takes about 3 seconds to finish MRC, which is really
fast (4 times faster than before).

To i.MX6SX/UL, two ethernet interfaces are supported.
Add ENET2 clock support:
1. Introduce a new input parameter "fec_id", only 0 and 1 are allowed.
To value 1, only i.MX6SX/UL can pass the check.
2. Modify board code who use this api to follow new api prototype.

Move most macro definitions and prototypes into
"arch/arm/include/asm/imx-common/sys_proto.h" to avoid duplicated
function prototypes and marco definitions for different i.MX SoCs.
This patch do not remove the sys_proto.h for different i.MX SoCs,
because we need to modify lots of driver code and others. This patch
remove duplicated macros and prototypes and incude "sys_proto.h"
of imx-common for each sys_proto.h of different i.MX platforms.
Then later we should avoid add stuff in sys_proto.h of each platform,
and modify driver to include common sys_proto.h.

Also write get_imx_type to replace get_cpu_type, since we have

Move TARGET_xx Kconfig option based on mx6 to arch/arm/cpu/armv7/mx6/Kconfig.
Add enable "CONFIG_ARCH_MX6" for boards based on mx6.
Then we can choose target boards using "make ARCH=arm menuconfig"
with ARCH_MX6 defined.
If using original way, we have no chance to enable ARCH_MX6 when
"make menuconfig". Even define CONFIG_ARCH_MX6=y in xx_defconfig,

Remove this ad-hoc mkimage invocation in MXS Makefile and replace
it with the standard mkimage rule instead.
This patch fixes recent build issues introduced by the patch
92a655c mkimage: Set up a file size parameter and keep it updated
These build issues could be triggered by building for example the
MX28EVK and the u-boot.sb image:
$ make mx28evk_defconfig
$ make V=1 u-boot.sb
[...]
make -f ./scripts/Makefile.build obj=arch/arm/cpu/arm926ejs/mxs u-boot.sb
./tools/mkimage -n arch/arm/cpu/arm926ejs/mxs/mxsimage.mx28.cfg -T mxsimage u-boot.sb
./tools/mkimage: Can't open (null): Bad address

make[1]: *** [u-boot.sb] Error 1
Makefile:989: recipe for target 'u-boot.sb' failed
make: *** [u-boot.sb] Error 2

DEVDISRn registers provides a mechanism for gating clocks of IP blocks
that are not used. Here we implement hwconfig option to allow users
to disable unused peripherals on the board.
For ex. If eSDHC/qDMA/eDMA are unused and with disabled status in dts,
User can enable CONFIG_FSL_DEVICE_DISABLE and set "devdis:esdhc,qdma,edma"
in hwconfig, thus ESDHC controller & eDMA/qDMA will be clock gated to
save more power.
