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.

The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
images and u-boot, and does this for virtual platforms by using
semihosting. This commit extends this idea by allowing u-boot to also
use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.
Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an
untested armv7 placeholder for the service trap opcode.
Please refer to doc/README.semihosting for a more detailed description
of semihosting and how it is used with the armv8 virtual platforms.

I2C read transactions are typically implemented as follows:
START(write) address REPEATED_START(read) data... STOP
However, Tegra's I2C driver currently implements reads as follows:
START(write) address STOP START(read) data... STOP
This sequence confuses at least the AS3722 PMIC on the Jetson TK1 board,
leading to corrupted read data in some cases. Fix the driver to chain
the transactions together using repeated starts to solve this.

With the changes to the i2c framework (and adopting the omap24xx_i2c
driver to them) we can no longer call i2c functions prior to gd having
been set and cleared. When SPL booting, this is handled by setting gd
to point to SRAM in s_init. However in the cases where we are loaded

normal hooks to slightly delay these calls.

We have two contexts for booting these platforms. One is SPL which is
roughly: reset, cpu_init_crit, lowlevel_init, s_init, sdram_init, _main,
board_init_f from SPL, ... then U-Boot loads. The other is a
memory-mapped XIP case (NOR or QSPI) where we do not run an SPL. In
this case we go, roughly: reset, cpu_init_crit, lowlevel_init, s_init,
_main, regular board_init_f.
In the first case s_init will set a valid gd and then be able to call
sdram_init which in many cases will need i2c (which needs a valid gd for
gd->cur_i2c_bus). In this second case we must (and are able to and
should) defer sdram_init() into dram_init() called by board_init_f as gd
will have been set in _main and cleared in board_init_f.

It's "correct" in so far as it works (the boards.cfg config stuff
#defines things to 1), but I think you are right that it isn't the
preferred style. But...

...I had thought that it was to support some other board which wasn't
being upstreamed right now, so eventually useful and harmless for now,
but I've just checked and it isn't actually used by any of the boards in
u-boot-sunxi.git. So rather than fix it to use #ifdef lets drop it.
Rather than resend the entire series, here is v5.1 of this patch.

GPMC controller on TI's OMAP SoC is general purpose controller to interface
with different types of external devices like;
- parallel NOR flash
- parallel NAND flash
- OneNand flash
- SDR RAM
- Ethernet Devices like LAN9220
Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.
Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c
files into single omap-common/mem-common.c
However, actual platforms specific register config values are still sourced
from corresponding platform specific headers like;
AM33xx: arch/arm/include/asm/arch-am33xx/mem.h
OMAP3: arch/arm/include/asm/arch-omap3/mem.h
OMAP4: arch/arm/include/asm/arch-omap4/mem.h
OMAP4: arch/arm/include/asm/arch-omap5/mem.h
Also, CONFIG_xx passed by board-profile decide config for which set of macros
need to be used for initialization
CONFIG_NAND: initialize GPMC for NAND device
CONFIG_NOR: initialize GPMC for NOR device
CONFIG_ONENAND: initialize GPMC for ONENAND device

A few changes are made to the Tegra EHCI driver so that it can set
everything up for device-mode operation on the first USB controller.
This can be used in conjunction with ci_udc.c to operate as a USB
device.
Detailed changes are:
* Rename set_host_mode() to set_up_vbus() since that's really what it
does.
* Modify set_up_vbus() to know whether it's initializing in host or
device mode, and:
- Skip the external VBUS check in device mode, since external VBUS is
expected in this case.
- Disable VBUS output in device mode.
* Modify init_phy_mux() to know whether it's initializing in host or
device mode, and hence skip setting USBMODE_CM_HC (which enables host
mode) in device mode. See the comments in that function for why this
is safe w.r.t. the ordering requirements of PHY selection.
* Modify init_utmi_usb_controller() to force "b session valid" in device
mode, since the HW requires this. This is done in UTMI-specific code,
since we only support device mode on the first USB controller, and that
controller can only talk to a UTMI PHY.
* Enhance ehci_hcd_init() to error-check the requested host-/device-mode
vs. the dr_mode (dual-role mode) value present in device tree, and the
HW configurations which support device mode.
* Enhance ehci_hcd_init() not to skip HW initialization when switching
between host and device mode on a controller. This requires remembering
which mode the last initialization used.

U-Boot on Tegra30 currently selects a main CPU frequency that cannot be
supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values
on some others. This can result in unreliable operation of the main CPUs.
Resolve this by switching to a CPU frequency that can be supported by any
SKU. According to the following link, the maximum supported CPU frequency
of the slowest Tegra30 SKU is 600MHz:
repo http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary
branch l4t/l4t-r16-r2
path arch/arm/mach-tegra/tegra3_dvfs.c
table cpu_dvfs_table[]
According to that same table, the minimum VDD_CPU required to operate at
that frequency across all SKUs is 1.007V. Given the adjustment resolution
of the TPS65911 PMIC that's used on all Tegra30-based boards we support,
we'll end up using 1.0125V instead.
At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates
that VDD_CORE must be at least 1.2V on all SKUs. According to
tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree),
that voltage is safe for all SKUs.
An alternative would be to port much of the code from tegra3_dvfs.c and
tegra3_speedo.c in the kernel tree mentioned above. That's more work
than I want to take on right now.
While all the currently supported boards use the same regulator chip for
VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we
add some small conditional code to select how VDD_CORE is programmed. If
this becomes more complex in the future as new boards are added, or we
end up adding code to detect the SoC SKU and dynamically determine the
allowed frequency and required voltages, we should probably make this a
runtime call into a function provided by the board file and/or relevant
PMIC driver.

* Adds gpio pin numbering support for EXYNOS SOCs.
To have consistent 0..n-1 GPIO numbering the banks are divided
into different parts where ever they have holes in them.
* Rename GPIO definitions from GPIO_... to S5P_GPIO_...
These changes were done to enable cmd_gpio for EXYNOS and
cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
getting a error during compilation.
* Adds support for name to gpio conversion in s5p_gpio to enable
gpio command EXYNOS SoCs. Function has been added to asm/gpio.h

read support as well. This means we can be given one of two boot device
values, but don't care which it is, so perform a fixup on the QSPI_4
value. We add a qspiboot build target to better show how you would use
QSPI as a boot device in deployment. When we boot from QSPI, we can
check the environment for 'boot_os' to control Falcon Mode.

TI platforms such as OMAP5uevm, PandaBoard, use equivalent

Consolidate this to a generic location such that other TI platforms such

Replace the custom bit manipulation function sr32() by standard I/O
accessors. A major motivation for this cleanup was the fact, that a
number of calls of that function resulted in 32 bit wide shift
operations on u32 data, which according to the C-ISO/IEC-9899-Standard
provokes undefined behaviour:
6.5.7 Bitwise shift operators
...
If the value of the right operand is negative or is greater
than or equal to the width of the promoted left operand, the
behavior is undefined.

Use smaller fields in the Tegra pinmux structures in order to pack the
data tables into a smaller space. This saves around 1-3KB for the SPL
and around 3-8KB for the main build of U-Boot, depending on the board,
which SoC it uses, and how many pinmux table entries there are.
In order to pack PMUX_FUNC_* into a smaller space, don't hard-code the
values of PMUX_FUNC_RSVD* to values which require 16 bits to store them,
but instead let their values be assigned automatically, so they end up
fitting into 8 bits.

Clean up the naming of pinmux-related objects:
* Refer to drive groups rather than pad groups to match the Linux kernel.
* Ensure all pinmux API types are prefixed with pmux_, values (defines)

* Modify a few type names to make their content clearer.
* Minimal changes to SoC-specific .h/.c files are made so the code still
