f479cec3b6 imx: i.mx6q: add the initial support for LogicPD i.MX6Q SOM
Logic PD has an i.MX6Q system on module (SOM) with a development kit. The
SOM has a built-in microSD socket, DDR and NAND flash.  The development kit
has an SMSC Ethernet PHY, serial debug port and a variety of peripherals.
This have been verified to boot the i.MX6Q version over either SD
on the development kit or NAND built into the SOM.  Items in the dtsi file
are specific to the SOM itself.  Items in the dts file are in the baseboard.
Future versions of the SOM will come out supporting the same basebord and
potentially future base boards will come out supporting the same SOM.

01abae4d04 Remove various unused interrupt related code
With d53ecad92f some unused interrupt related code was removed.
However all of these options are currently unused.  Rather than migrate
some of these options to Kconfig we just remove the code in question.

The only related code changes here are that in some cases we use
CONFIG_STACKSIZE in non-IRQ related context.  In these cases we rename
and move the value local to the code in question.

e4916e850b ARM: rename CONFIG_TIMER_CLK_FREQ to COUNTER_FREQUENCY
Many ARMv8 boards define a constant COUNTER_FREQUENCY to specify the
frequency of the ARM Generic Timer (aka. arch timer).
ARMv7 boards traditionally used CONFIG_TIMER_CLK_FREQ for the same
purpose. It seems useful to unify them.
Since there are less occurences of the latter version, lets convert all
users over to COUNTER_FREQUENCY.

622bad103b armv7m: Add SysTick timer driver
The SysTick is a 24-bit down counter that is found on all ARM Cortex
M3, M4, M7 devices and is always located at a fixed address.

The number of reference clock ticks that correspond to 10ms is normally
defined in the SysTick Calibration register's TENMS field. However, on some
devices this is wrong, so this driver allows the clock rate to be defined
using CONFIG_SYS_HZ_CLOCK.

19a75b8cf8 arm: omap3: Bring back ARM errata workaround 725233
The workaround for ARM errata 725233 had been lost since
commit 45bf05854b (armv7: adapt omap3 to the new cache
maintenance framework). Bring it back in order to avoid
very difficult to reproduce, but actually encountered in
the wild CPU deadlocks when running software rendered
X11 desktop on OMAP3530 hardware.

dffb4931fd armv8: fsl-lsch2: add workaround for erratum A-010635
Read DMA operations causes CRC error on armv8 chassis 2 platforms
due to the erratum A-010635.
In order to support sata on these platforms, ECC needs to be disabled.

4961eafc25 armv8: layerscape: Update early MMU for DDR after initialization
In early MMU table, DDR has to be mapped as device memory to avoid
speculative access. After DDR is initialized, it needs to be updated
to normal memory to allow code execution. To simplify the code,
dram_init() is moved into a common file as a weak function.

7f9b9f318f armv8: mmu: Add a function to change mapping attributes
Function mmu_change_region_attr() is added to change existing mapping
with updated PXN, UXN and memory type. This is a break-before-make
process during which the mapping becomes fault (invalid) before final
attributres are set.
