73feefdc1a am33xx: Stop using PHYS_DRAM_1 define
We defined PHYS_DRAM_1 to 0x80000000 (start of DRAM) and then used this
for CONFIG_SYS_SDRAM_BASE.  But then we kept on referencing PHYS_DRAM_1
in other places.  Change to directly setting CONFIG_SYS_DRAM_BASE and
then using that name in code.

5c119cb2be 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.

cf8d0057aa 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.

2e6bc67019 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.

After commit:

  79cd2f814b 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.

edfcf85a0a am33xx/omap4+: Move SRAM_SCRATCH_SPACE_ADDR to <asm/arch/omap.h>
The location of valid scratch space is dependent on SoC, so move that
there.  On OMAP4+ we continue to use SRAM_SCRATCH_SPACE_ADDR.  On
am33xx/ti814x we want to use what the ROM defines as "public stack"
which is the area after our defined download image space.  Correct the
comment about and location of CONFIG_SPL_TEXT_BASE.

320d9746d3 am33xx: Correct NON_SECURE_SRAM_START/END
Prior to Sricharan's cleanup of the boot parameter saving code, we
did not make use of NON_SECURE_SRAM_START on am33xx, so it wasn't a
problem that the address was pointing to the middle of our running SPL.
Correct to point to the base location of the download image area.
Increase CONFIG_SPL_TEXT_BASE to account for this scratch area being
used.  As part of correcting these tests, make use of the fact that
we've always been placing our stack outside of the download image area
(which is fine, once the downloaded image is run, ROM is gone) so
correct the max size test to be the ROM defined top of the download area
to where we link/load at.

47c6ea076e ARM: OMAP: Add arch_cpu_init function
The boot parameters passed from SPL to UBOOT
must be saved as a part of uboot's gd data
as early as possible, before we will inadvertently
overwrite it. So adding a arch_cpu_init for the required
Socs to save it.

they are stored as a part of the global data 'gd'
structure. So read them from 'gd' instead.
