169b50efe2 board/BuR/common: incorrect check of dtb
The logical expression to check the dtb is incorrect in
load_devicetree.

The problem was indicated by cppcheck.

The inconsistent variable name dtppart is changed to dtbpart.

d5abcf94c7 ti: boot: Register the MMC controllers in SPL in the same way as in u-boot
To keep a consistent MMC device mapping in SPL and in u-boot, let's
register the MMC controllers the same way in u-boot and in the SPL.
In terms of boot time, it doesn't hurt to register more controllers than
needed because the MMC device is initialized only prior being accessed for
the first time.
Having the same device mapping in SPL and u-boot allows us to use the
environment in SPL whatever the MMC boot device.

b616d9b0a7 nand: Embed mtd_info in struct nand_chip
nand_info[] is now an array of pointers, with the actual mtd_info
instance embedded in struct nand_chip.

This is in preparation for syncing the NAND code with Linux 4.6,
which makes the same change to struct nand_chip.  It's in a separate
commit due to the large amount of changes required to accommodate the
change to nand_info[].

568cfb4d7b board/BuR: drop ETH-support in SPL-Stage
During very early prototype-phase we did boot the AM335x boards
initially from CPSW-EMAC.

Now we don't need this feature anymore.

So we drop it to save MLO-space and having therefore a more quickly
boot.

9b63ba3727 board/BuR/common: support timer5 for pwm-backlight
in future we support yet another b&r am335x based board, where Timer 5 is
wired to backlight-driver.

So we introduce a new driver-type '2' to setup timer5 instead timer6.

99f7247211 board/BuR/tseries: Add simplefb support
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.

d804452bf4 board/BuR/tseries: take usage of CONFIG_LCD_ROTATION
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

2b5b2be5e9 board/BuR/common: move I2C initialization from common part to board-specific
At this time I2C and responsible pin-mux is setup during PMIC initialziation
within common.c, this is possible because today PMIC is always connected on
I2C0.

In Future this will be changed, PMIC isn't anymore connected to bus0 in call
cases.

So we do following:
- rename enable_i2c_pin_mux0 to enable_i2c_pin_mux to be generic for enabling
  pin-mux on different or more busses.
- move the call to i2c_pin_mux and i2c_init from common.c to the specific
  board.c
