382bee57f1 env: Rename setenv() to env_set()
We are now using an env_ prefix for environment functions. Rename setenv()
for consistency. Also add function comments in common.h.

80b9c3bb80 board: toradex: colibri_vf: Add DCU support for Colibri Vybrid
The Vybrid SoC family has the same display controller unit (DCU)
like the LS1021A SoC. This patch adds platform data, pinmux defines
and clock control to enable the driver for Toradex Colibri Vybrid
module.

0eba4c41ca colibri_vf: use same NAND clock as Linux uses
Currently a divider of 6 has been used, leading to following NAND
Flash Controller (NFC) clocks:
VF61: 27.7 MHz (166.7MHz bus clock)
VF50: 22 MHz (132MHz bus clock)

The NAND Flash Memory used on VF50 allows to use clock speed of
up to 33MHz, while the Flash Memory of VF61 allows 50MHz. We can
use the same divider of 4 on both modules to configure the maximal
possible clock speeds:
VF61: 41.7 MHz
VF50: 33 MHz

9e73c1b7d1 colibri_vf: cleanup USB clock initialization
Use the same preprocessor define to enable clocks as we use to
enable the driver. Make sure that the necessary PLL's are on
(they get enabled by boot ROM by default, so this is more for
completness).

6119b0f764 colibri_vf: use device-tree for MTD partitions
Use device-tree fixup to communicate the MTD partitions to the
kernel. U-Boot's mtdparts environment variable will be used as
partition source for the device-tree based partition table too.

37fa41256b toradex: allow custom fdt board setup in board file
The config block support currently uses the ft_board_setup function
to patch the device tree with config block information. However, this
does not allow to patch the device tree with board specific information.
Rename the common setup function to ft_common_board_setup and use the
call it from the board files directly.

01a8cf9151 colibri_vf: Add board_usb_phy_mode function
Add board_usb_phy_mode function for detecting whether a port is
being used as host or client using a GPIO. On Colibri Vybrid we
provide GPIO 102 for this very same purpose.

d45fd018c8 colibri_vf: Fix bstlen field
Commit 3f353cecc ("vf610: refactor DDRMC code") changed the original
bstlen field from 3 to 0.

Restore the original value for proper behaviour.

Based on the patch from Anthony Felice <tony.felice@timesys.com>
for the vf610twr board.

3f353ceccb vf610: refactor DDRMC code
The VF610 DDRMC driver code contains settings which are
board-specific. Move these out to boards so that new boards
can define their own without having to modify the driver.

09cfa8ee6a colibri_vf: Enable board specific USB initialisation for USB pen gpio
Add IOMUX for the pad used as USB pen. This needs to be driven low for
the Iris and Viola boards where it is pulled up high by default. This is
required for the USB host functionality to work on these boards. Use the
board specific weak initialisation function, to drive the pin low which
would be called on "usb start".

e7b860fa4d ARM: vf610: Initial integration for Colibri VF50/VF61
This adds initial support for Colibri VF50/VF61 based on Freescale
Vybrid SoC.

- CPU clocked at 396/500 MHz
- DDR3 at 396MHz
  - for VF50, use PLL2 as memory clock (synchronous mode)
  - for VF61, use PLL1 as memory clock (asynchronous mode)
- Console on UART0 (Colibri UART_A)
- Ethernet on FEC1
- PLL5 based RMII clocking (E.g. No external crystal)
- UART_A and UART_C I/O muxing
- Boot from NAND by default

Tested on Colibri VF50/VF61 booting using serial loader over UART.
