The PicoZed is a System-on-Module board which is marketed as part of
the ZedBoard/MicroZed/etc. collection. It includes a Zynq-7000
processor.

This patch adds support that covers all the variants of the PicoZed
including the SKUs with Z7010/Z7020 and Z7015/Z7030 Zynq chips. This
patch set however only covers support for the System-on-Module and does
not cover any extra components that are available on carrier boards
(except those that are fanned out of the module itself).

More information on this board, its variants and available carrier
boards is available at: http://zedboard.org/product/picozedSigned-off-by: NNathan Rossi <nathan.rossi@xilinx.com>

Upto now flash sector_size is assigned from params which isn't
necessarily a sector size from vendor, so based on the SECT_*
flags from flash_params the erase_size will compute and it will
become the sector_size finally.

total 2 MiB, mapped at ffe00000

With SPI flash moving to driver model, commit fbb09918 "dm: Convert
spi_flash_probe() and 'sf probe' to use driver model" ignored the
SST flash-specific write op (byte program & word program), which
actually broke the SST flash from wroking.

This commit makes SST flash work again under driver model, by adding
SST flash-specific handling in the spi_flash_std_write().

After syncing the sunxi dts files with the upstream kernel dm/fdt sunxi
builds would no longer boot.

The problem is that stdout-path is now set like this in the upstream dts
files: stdout-path = "serial0:115200n8". The use of options in of-paths,
either after an alias name, or after a full path, e.g. stdout-path =
"/soc@01c00000/serial@01c28000:115200", is standard of usage, but something
which the u-boot dts code so far did not handle.

This commit fixes this, adding support for both path formats.

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

Implemented fb_set_reboot_flag() for OMAP5 to set
an environment variable 'dofastboot' when reboot-bootloader called.

This environment variable will be checked in boot command and fastboot
will be called if the variable is set.
If the bootcmd env variable of OMAP5 common is overwritten with board-specific
command, then these changes will not apply.

This was originally intended for DRA7 platform, but now applies to all OMAP5.
