This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

Becuase the board select menu in arch/arm/Kconfig is too big,
move the Tegra board select menu to tegra/Kconfig.
Insert the Tegra SoC select menu between the arch select and the
board select.
Architecture select
|-- Tegra Platform (Tegra)
|- Tegra SoC select (Tegra20 / 30 / 114 / 124)
|- Board select
Consolidate also common settings (CONFIG_SYS_CPU="armv7" and
CONFIG_SYS_SOC="tegra*") and always "select" CONFIG_SPL as follows:
config TEGRA
bool
select SPL

We are about to switch to Kconfig in the next commit.
But there are something to get done beforehand.
In Kconfig, include/generated/autoconf.h defines boolean
CONFIG macros as 1.
CONFIG_SPL and CONFIG_TPL, if defined, must be set to 1.
Otherwise, when switching to Kconfig, the build log
would be sprinkled with warning messages like this:
warning: "CONFIG_SPL" redefined [enabled by default]

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.

Before this commit, USE_PRIVATE_LIBGCC was defined in
arch-specific config.mk and referenced in
arch/$(ARCH)/lib/Makefile.
We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.
By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)
Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.
It means Tegra enables PRIVATE_LIBGCC only for SPL.
We can describe the same behavior by adding
#ifdef CONFIG_SPL_BUILD
# define CONFIG_USE_PRIVATE_LIBGCC
#endif
to include/configs/tegra-common.h.

Currently all Tegra SoCs are assumed to have 32 byte cache lines. This
isn't true for Tegra114, however, which uses 4 Cortex-A15 cores and
therefore uses a cache line size of 64 bytes. Move the cache line size
setting to the per-SoC common configuration file.

Remove SPL-related ASSERT() in arch/arm/cpu/u-boot.lds
as this file is never used for SPL builds.
Rewrite the ASSERT() in arch/arm/cpu/u-boot-spl.lds
to separately test image (text,data,rodata...) size,
BSS size, and full footprint each against its own max,
and make Tegra boards check full footprint.
Also, output section mmutable is not used in SPL builds.
Remove it.
Finally, update README regarding the (now homogeneous)
semantics of CONFIG_SPL_[BSS_]MAX_SIZE and add the new
CONFIG_SPL_MAX_FOOTPRINT macro.

Enable a common set of partition types, filesystems, and related
commands in tegra-common.h, so that they are available on all Tegra
boards. This allows boot.scr (loaded and executed by the default
built-in environment) on those boards to assume that certain features
are always available.
Do this in tegra-common.h, so that individual board files can undefine
the features if they really don't want any of them.
