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

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.

If CONFIG_API is ever to be enabled on Tegra, this define must be set,
since api/api_storage.c uses it.
A couple of annoyting things about CONFIG_SYS_MMC_MAX_DEVICE
1) It isn't documented in README. The same is true for a lot of similar
defines used by api_storage.c.
2) It doesn't represent MAX_DEVICE but rather NUM_DEVICES, since the
valid values are 0..n-1 not 0..n.
However, I this patch does not address those shortcomings.

We only need u-boot to bother about a single core in the QEMU machine.
Everything that would require additional knowledge of more cores gets
handled by QEMU and passed straight into the payload we execute.
Because of this setup, it would be counterproductive to enable SMP support
in u-boot. We would have to rip CPUs out of already existing spin tables
and respin them from u-boot. It would be a pretty big mess.
So only assume we have a single core. This fixes errors about CONFIG_MP
being disabled.

[York Sun: fix CONFIG_SYS_QE_FMAN_FW_ADDR in T4240RDB.h]
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.
