Since the used AM3352 SoC doesn't have GPU it isn't allways necessary to build
in complete drm-stuff into linux kernel. In very small applications only we use
the simple-framebuffer.
So we have 2 use-cases:
- device operating on drm-driver (let simplefb node disabled)
- device operating on simplefb-driver (activate simplefb node and reserve mem)
The decision is made by means of "simplefb" environment variable.
simplefb = 0
we don't enable the (maybe) existing simplefb node and all the rest around
display is up to the linux-kernel. We just disable the backlight, beceause we
do not want see the flicker during take over of drm-driver.
simplefb = 1
we enable the (maybe) existing simplefb node and reserve framebuffers size
in memory.

the CONFIG_LCD_NOSTDOUT feature never had become mainline in uboot due to the
fact that the problem of "not writing out whole console to lcd" can be solved
with another way.
So we remove this unnary define.

We take use of the new LCD_ROTATION feature.
The information about how the display is rotated is taken from B&R specific
(/factory-settings/rotation) information in the devicetree.
The information there is stored as string (cw, ud, ccw, none) since starting
support of this devices and cannot be changed, so we have to convert it into
none = 0
cw = 1
ud = 2
ccw = 3

The NAND-version has been become a bit orphan.
Now we need to reactivate it, so bring necessary things:
- loading devicetree
- switch control signal to correct pins
- setup pinmux
- default-environment
up to date.

Due to several changes of the boot-process we've redesigned the default-
environment settings completly.

It is often necessary to "break in" into boards bootloader commandline if
something fails or even for development purposes some parameters have to be
changed.
So we enable u-boot's CONFIG_NETCONSOLE feature.
We also modify Networksettings to apply with this new use-case.

Currently, CONFIG_SPL_SPI_* #defines are used for controlling SPI boot in
SPL. These #defines do not allow the user to select SPI mode for the SPI flash
(there's no CONFIG_SPL_SPI_MODE, so the SPI mode is hardcoded in
spi_spl_load.c), and duplicate information already provided by
CONFIG_SF_DEFAULT_* #defines.
Kill CONFIG_SPL_SPI_*, and use CONFIG_SF_DEFAULT_* instead.

In the case of SPL on these boards we only need environment for
SPL_USBETH, so it's safe to normally use ENV_IS_NOWHERE and SPL+NAND
does not support environment today.

OMAP3 used GPMC_NAND_ECC_LP_x8_LAYOUT and GPMC_NAND_ECC_LP_x16_LAYOUT macros
to configure GPMC controller for x7 or x8 bit device connected to its interface.
Now this information is encoded in CONFIG_SYS_NAND_DEVICE_WIDTH macro, so above
macros can be completely removed.

Since B&R boards uses only MMC-Controller #1, it only
wastes time if we initialize #0 first to see that there is nothing.
