Canyonlands (460EX) shares the first PCIe interface with the SoC SATA
interface. This usage can be configured with the jumper J6. This patch
displays the current configuration upon bootup and changes the PCIe
init loop, to only initialize the availabel PCIe slots.

This patch adds support for the AMCC Glacier 460GT eval board.
The main difference to the Canyonlands board are listed here:

- 4 ethernet ports instead of 2
- no SATA port
- no USB port

Currently EMAC2+3 are not working. This will be fixed in a later
release.

460EX doesn't support a fixed bootstrap option to boot from 512 byte page
NAND devices. The only bootstrap option for NAND booting is option F for
2k page devices. So to boot from a 512 bype page device, the I2C bootstrap
EEPROM needs to be programmed accordingly.

This patch adds basic NAND booting support for the AMCC Canyonlands aval
board and also adds support to the "bootstrap" command, to enable NAND
booting I2C setting.

Tested with 512 byte page NAND device (32MByte) on Canyonlands.
