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.

h/w read leveling enabled, so we must disable this.
Also, disabling h/w read leveling improves the MIF LVcc value
(LVcc value is the value at which DDR will fail to work properly).
Improving LVcc means we have enough voltage margin for MIF.
When h/w leveling is enabled, we have almost zero volatge margin.

going backwards across CPUs).
This patch instead initialises cntvoff_el2 with xzr, giving the register
a consistent value of zero on all CPUs.

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
directly by ROM (memory mapped NOR or QSPI) we need to make use of the
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.

arch/arm/include/asm/spl.h requires all SoCs to have

But many of them just define BOOT_DEVICE_* macros.
Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.
So they should not be archtecture specific, but be described as
a simpile enumeration.
This commit merges most of arch/arm/include/asm/arch-*/spl.h

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

And retore the div-value, not using the value of lowlevel_init.
(For using SDMMC4, this patch is needs)

ps7_init.c and ps7_init.h are supposed to be exported by hw project
and copied to board/xilinx/zynq/ directory.
We want them to be ignored by git.
So what we should do is to always treat them as external files
rather than replacing ps7_init.c
This commit does:
- Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c
and delete board/xilinx/zynq/ps7_init.c
- Compile board/xilinx/zynq/ps7_init.c only when it exists
- Add .gitignore to ignore ps7_init.c/h

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.

Define enum PMUX_FUNC_DEFAULT, which indicates that a table entry passed
to pinmux_config_pingrp()/pinmux_config_pingrp_table() shouldn't change
the mux option in HW.
For pins that will be used as GPIOs, the mux option is irrelevant, so we
simply don't want to define any mux option in the pinmux initialization
table.

This patch includes following changes :
* 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
to decode the input gpio name to gpio number.
Example: SMDK5420 # gpio set gpa00
