Introduce 'mx28evk_nand' target for saving environment variables into NAND.
The mx28evk board does not come with a NAND flash populated from the
factory. It comes with an empty slot (U23), which allows the insertion of a
48-pin TSOP flash device.
Tested with a K9LBG08U0D.

When loading a Freescale 2.6.35 on a mx28evk the following issue is seen:
sgtl5000_hw_read: read reg error : Reg 0x00
Device with ID register 0 is not a SGTL5000
Disabling CONFIG_CMD_I2C makes the sgtl5000 probe to succeed.
Mainline kernel does not show this problem.
Until the real cause is not identified, disable 'CONFIG_CMD_I2C' for the
time being.

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.

Tested on my Cardhu-A04 tablet, eMMC and SD-Card work fine, can load

T114 has a slightly different I2C clock, with a new (extra) divisor
in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C
clock is 100KHz +/- 3Hz on my Saleae Logic analyzer.
Added a new entry in compat_names for T114 I2C since it differs
from the previous Tegra SoCs. A flag is set when T114 I2C HW is
found so new features like the extra clock divisor can be used.

Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such,
some CPU errata exist, and must be worked around.
These must be worked around in the bootloader, since in general, the
kernel (especially a multi-platform kernel) needs to support being
launched in non-secure mode (normal world), and hence may not be able
to write to the CP15 register to enable these workarounds.

Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.
Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

Many SPL linker scripts needlessly include linker lists (aka LGAs).
Remove them whenever possible; keep it only in the seven am335x_evm
variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot),
where there is actual content in output section .u_boot_list.
This commit keeps all u-boot.bin and u-boot-spl.bin in ARM targets
byte-identical.

Currently there is no logical place to put the code that prepares the
splash image data. The splash image data should be ready in memory
before bmp_display() is called, and after the environment is ready
(since lcd.c looks for the splash image in an address specified by
the environment variable "splashimage").
Our window of opportunity in board_init_r() is therefore: between
env_relocate() and bmp_display(), and from the available options
only the lcd related functions in drv_lcd_init() seem appropriate
for such lcd oriented code.
Add the option to prepare the splash image data in lcd_logo() right
before it is sent to be displayed.

Because of our support for network-based SPL, we don't discard all of
the environment related functions. We however never make use of the
default CONFIG_EXTRA_ENV_SETTINGS items and as this variable grows, it
brings us closer to (or with some toolchains, over) our SPL size limit.
Never set this in the case of SPL.
