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.

1db503c4b9 ARM: vf610: Add SoC and CPU type detection
Vybrid product family consists of several rather similar SoC which
can be determined by softare during boot time. This allows use of
variable ${soc} for Linux device tree files. Detect VF5xx CPU's by
reading the CPU count register. We can determine the second number
of the CPU type (VF6x0) which indicates the presence of a L2 cache.

In order to avoid code duplication, move the DDR3 initialization to the

c19a8bc571 vf610twr: Tune DDR initialization settings
Removed settings in unsupported register fields. They didn’t
do anything, and in most cases, were not documented in the
reference manual.

Changed register settings to comply with JEDEC required values.

Changed timing parameters because they included full clock
periods that were doing nothing.

25839c0197 arm: vf610: fix anadig register struct
The anadig_reg structure started at the wrong offset (fixed by adding
reserved_0x000[4]), was missing some reserved field required for
alignment purpose (reserved_0x094[3] between pll4_denom and pll6_ctrl)
and further contained a too short reserved field causing further miss-
alignment (reserved_0x0C4[7]). Also, rename all the reserved fields
and using a memory offset based scheme for.

Discovered and tested by temporarily putting the following debug
instrumentation into board_init():
    struct anadig_reg *anadig = (struct anadig_reg *)ANADIG_BASE_ADDR;
    printf("&anadig->pll3_ctrl=0x%p\n", &anadig->pll3_ctrl);
    printf("&anadig->pll5_ctrl=0x%p\n", &anadig->pll5_ctrl);
