d1e5b4065e ARM: tegra: Enable non-cached memory
Some boards, most notably those with a PCIe ethernet NIC, require this
to avoid cache coherency problems. Since the option adds very little
code and overhead enable it across all Tegra generations. Other drivers
may also start supporting this functionality at some point, so enabling
it now will automatically reap the benefits later on.

b0e6ef4640 dm: i2c: tegra: Convert to driver model
This converts all Tegra boards over to use driver model for I2C. The driver
is adjusted to use driver model and the following obsolete CONFIGs are
removed:

   - CONFIG_SYS_I2C_INIT_BOARD
   - CONFIG_I2C_MULTI_BUS
   - CONFIG_SYS_MAX_I2C_BUS
   - CONFIG_SYS_I2C_SPEED
   - CONFIG_SYS_I2C

This has been tested on:
- trimslice (no I2C)
- beaver
- Jetson-TK1

It has not been tested on Tegra 114 as I don't have that board.

45ccec8f29 kconfig: move CONFIG_USE_PRIVATE_LIBGCC to Kconfig
The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86.
Those architectures should "select" HAVE_PRIVATE_LIBGCC and
CONFIG_USE_PRIVATE_LIBGCC should depend on it.

Currently, this option is enabled on Tegra boards and x86 architecture.
Move the definition from header files to Kconfig.

2fccd2d96b tegra: Convert tegra GPIO driver to use driver model
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.

ddd960e6c4 tegra: kconfig: move board select menu and common settings
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

4ce9957029 include: define CONFIG_SPL and CONFIG_TPL as 1
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]

f175603f7c ARM: tegra: set CONFIG_SYS_MMC_MAX_DEVICE
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.

cd2e46cb38 kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC
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.

semantics of CONFIG_SPL_[BSS_]MAX_SIZE and add the new
CONFIG_SPL_MAX_FOOTPRINT macro.
