After commit:

  79cd2f814b1c75efd47161ac27f4cbebf768240f config_cmd_default.h: Remove CONFIG_CMD_MEMTEST

It's not necessary to undef the CONFIG_CMD_MEMTEST, so we can remove it from
configuration file.

ARM: IGEP0033: Add support for Flattened Device Tree.

Now, the default kernel to boot the IGEP COM AQUILA is device tree based. As
old kernel is deprecated we should adapt the boot commands to use DTB files.

Also, with v3.9 and later of the Linux Kernel, uImage isn't builtable anymore
by default, so we should switch to use the bootz command.

ARM: IGEP0033: Remove CYGNUS name from header.

We will not use CYGNUS names for any IGEP COM based on AM335x processor,
so, to avoid confusion, remove from headers.

ARM: IGEP0033: Add support to boot from NAND.

Add to the default environment the possibily to boot from NAND using
a ubi rootfs. Also the partition scheme is set as follows:

                  Start      Size
    SPL         : 0x00000000 0x00080000 (512KiB)
    U-Boot      : 0x00080000 0x00100000 (1MiB)
    U-Boot Env  : 0x00180000 0x00020000 (128KiB)
    File System : 0x001C0000 -

The ubiboot script gets the kernel and the dtb file from the boot directory
of the File System.

ARM: IGEP0033: Remove duplicate / unused #defines.

As config was originally based on am335x_evm.h we have also some
duplicate / unnused #defines.

Commit 15191c91 removed these #defines on various AM335x boards but not
for IGEP COM AQUILA. This patch simply removes them for this board.

ARM: igep00x0.h: Enable the use of CMD_EXT4, CMD_FS_GENERIC and zImage.

Able to load the kernel from some form of ext[234] or FAT. Also, with v3.9 and
later of the Linux Kernel, uImage isn't builtable anymore by default, so we
should switch to use the bootz command.
