[U-Boot] [PATCH 2/2] ARM: Add support for IGEP COM AQUILA/CYGNUS

[Enric Balletbo i Serra <eballetbo@gmail.com>]

From: Enric Balletbo i Serra <eballetbo@iseebcn.com>

The IGEP COM AQUILA and CYGNUS are industrial processors modules with
following highlights:

  o AM3352/AM3354 Texas Instruments processor
  o Cortex-A8 ARM CPU
  o 3.3 volts Inputs / Outputs use industrial
  o 256 MB DDR3 SDRAM / 128 Megabytes FLASH
  o MicroSD card reader on-board
  o Ethernet controller on-board
  o JTAG debug connector available
  o Designed for industrial range purposes
