"MAGIC" - 208 - An option whose presence and content verifies to
the PXELINUX bootloader that the options numbered 209-211 are for
the purpose as described herein.
"ConfigFile" - 209 - Configures the path/filename component of the
configuration file's location, which this bootloader should use to
configure itself.
"PathPrefix" - 210 - Configures a value to be prepended to the
ConfigFile to discern the directory location of the file.
"RebootTime" - 211 - Configures a timeout after which the
bootstrap program will reboot the system (most likely returning it
to PXE).

Move NON_SECURE_SRAM_START from 0x40304000 to 0x40303000 and
move u-boot-spl load address from 0x40304350 to 0x40303080.
This allows it to stay under 0x4030c000 which is what the TRM
says it must do. SRAM actually starts at 0x40300000 on GP
devices but was set to 0x40304000 to be the same as Secure
devices so this breaks that.

Some boot scripts fail without this. This makes OMAP4

Removing boot.scr support broke some external bootscripts
that depended on it.
This patch restores boot.scr support but leaves uEnv.txt
support in.
uEnv.txt still works and if both files exist then uEnv.txt
takes precedence.

The panda board has a usb nic but the nic has no
rom. Use the die-id to generate a unique address.
This is derived from an RFC kernel patch by Andy Green
that does the same thing:

Size problems when trying to include usb, mmc and fat

When booting via spl the parameter layout is apparently different
and this leads to following bad pointers.
For now just work around the issue by checking pointers before
following them.

If the net driver has setup a valid ethernet address and an ethernet
address is not set in the environment already, then set the environment
variables from the net driver setting
This enables pxe booting on boards which don't set ethaddr env variable.

This patch creates a new config for the A5 dual core tile that includes the
generic config for the Versatile Express platform.
The generic config has been modified to provide support for the Extended
Memory Map, as used on the A5 core tile. A5 does not support the legacy
memory map.

The current ca9x4_ct_vxp platform contains support for a Versatile Express
motherboard with a quad core A9 core tile.
This patch is the first stage of making separating the Versatile Express
motherboard code and the A9 specific code, before adding support for the
dual core A5 core tile.
