Generate the PSCI node in the device tree.
Also add a reserve section for the "secure" code that lives in
in normal RAM, so that the kernel knows it'd better not trip on
it.

Allow the switch to a second stage secure monitor just before
switching to non-secure.
This allows a resident piece of firmware to be active once the
kernel has been entered (the u-boot monitor is dead anyway,
its pages being reused).

The current non-sec switching code suffers from one major issue:
it cannot run in secure RAM, as a large part of u-boot still needs
to be run while we're switched to non-secure.
This patch reworks the whole HYP/non-secure strategy by:
- making sure the secure code is the *last* thing u-boot executes
before entering the payload
- performing an exception return from secure mode directly into
the payload
- allowing the code to be dynamically relocated to secure RAM
before switching to non-secure.
This involves quite a bit of horrible code, specially as u-boot
relocation is quite primitive.

Before switching to non-secure, make sure that CNTVOFF is set
to zero on all CPUs. Otherwise, kernel running in non-secure
without HYP enabled (hence using virtual timers) may observe
timers that are not synchronized, effectively seeing time
going backward...

PISMO_xx macros were used to define 'Platform Independent Storage MOdule'
related GPMC configurations. This patch
- Replaces these OMAP3 specific macros with generic CONFIG_xx macros as provided
by current u-boot infrastructure.
- Removes unused redundant macros, which are no longer required after
merging of common platform code in following commit

Fixes commit a0a37183bd75e74608bc78c8d0e2a34454f95a91
ARM: omap: merge GPMC initialization code for all platform
1) NAND device are not directly memory-mapped to CPU address-space, they are
indirectly accessed via following GPMC registers:
- GPMC_NAND_COMMAND_x
- GPMC_NAND_ADDRESS_x
- GPMC_NAND_DATA_x
Therefore from CPU's point of view, NAND address-map can be limited to just
above register addresses. But GPMC chip-select address-map can be configured
in granularity of 16MB only.
So this patch uses GPMC_SIZE_16M for all NAND devices.
2) NOR device are directly memory-mapped to CPU address-space, so its
address-map size depends on actual addressable region in NOR FLASH device.
So this patch uses CONFIG_SYS_FLASH_SIZE to derive GPMC chip-select address-map
size configuration.

The errata is applicable on all OMAP4 (4430 and 4460/4470) and OMAP5
ES 1.0 devices. The current revision check erroneously implements this
on all DRA7 varients and with DRA722 device (which has only 1 EMIF instance)
infact causes an asynchronous abort and ends up masking it in CPSR,
only to be uncovered once the kernel switches to userspace.

Use KS2_ prefix in all definitions, for that replace K2HK_ prefix and
add KS2_ prefix where it's needed. It requires to change names also
in places where they're used. Align lines and remove redundant
definitions in kardware-k2hk.h at the same time.
Using common KS2_ prefix helps resolve redundant redefinitions and
adds opportunity to use KS2_ definition across a project not thinking about
what SoC should be used. It's more convenient and we don't need to worry
about the SoC type in common files, hardware.h will think about that.
The hardware.h decides definitions of what SoC to use.

This driver is needed in case if keystone driver is used.
Currently only keystone_net driver uses it. So to avoid

Commit a0a37183 (ARM: omap: merge GPMC initialization code for all
platform) broke NAND on OMAP3 based platforms. I noticed this while
testing the latest 2014.07-rc version on the TAO3530 board. NAND
detection did not work with this error message:
NAND: nand: error: Unable to find NAND settings in GPMC Configuration - quitting
As OMAP3 configs don't set CONFIG_NAND but CONFIG_NAND_CMD. the GPMC
was not initialized for NAND at all. This patch now fixes this issue.
Tested on TAO3530 board.

Adding support to load and start the Layerscape Management Complex (MC)
firmware. First, the MC GCR register is set to 0 to reset all cores. MC
firmware and DPL images are copied from their location in NOR flash to
DDR. MC registers are updated with the location of these images.
Deasserting the reset bit of MC GCR register releases core 0 to run.
Core 1 will be released by MC firmware. Stop bits are not touched for
this step. U-boot waits for MC until it boots up. In case of a failure,
device tree is updated accordingly. The MC firmware image uses FIT format.
