The u-boot.lds file is common for all omap boards.
Move a cleaned up version to the cpu layer and add makefile logic to use it.

Zoom2 is a new board from Texas Instruments and LogicPD

The logicpd web site is a good source for general information on this board.
Please start looking here if the below links are broken.
http://www.logicpd.com

This is a pdf of the product
http://www.logicpd.com/sites/default/files/1012659A_Zoom_OMAP34x-II_MDP_Brief.pdf
This is the product description web page
http://www.logicpd.com/products/development-kits/texas-instruments-zoom%E2%84%A2-omap34x-ii-mdp

This patch provides a zoom2 base target by copying zoom1 and by making some
obvious changes.

To configure, run
make omap3_zoom2_config

  To: u-boot

Port the linux kernel's omap gpio interface to u-boot.
The orignal source is in linux/arch/arm/plat-omap/gpio.c

See doc/README.omap3 for instructions on use.

The logicpd web site is a good source for general information on this board.
Please start looking here if the below links are broken.
http://www.logicpd.com

This is a pdf of the product
http://www.logicpd.com/sites/default/files/1012659A_Zoom_OMAP34x-II_MDP_Brief.pdf

This is a pdf of the product quick start guide.
The debug board is described here.
http://support.logicpd.com/downloads/1165/

This is a wiki showing the debug board in use
https://omapzoom.org/gf/project/omapzoom/wiki/?pagename=GettingStartedWithZoomII_AKA_OMAP34XII_MDP

The zoom2 has an auxillary board that contains the serial, net, jtag and
battery simulator.  This change supports a runtime check if the debug board is
connected.

Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board.
The default serial is from the USB connector on left side of the debug board.
The USB connector will produce 2 of the 4 UARTS.  On your host pick the first
enumeration.

The serial port set up is the same with Zoom1.
Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow.

The kernel bootargs are
console=ttyS3,115200n8

Port version 2.6.27 of the linux kernel's omap gpio interface to u-boot.
The orignal source is in linux/arch/arm/plat-omap/gpio.c

See doc/README.omap3 for instructions on use.
