a30f519bd0 ZOOM2 detect the version of the zoom2 board at runtime.
There are currently 3 versions of the zoom2 board.
The production board, that is currently being released.
The beta board, similar in form to the production board but not released.
The alpha board, a set of PCBs with a very limited circulation.

GPIO 94 is used to determine the version of the board. If GPIO 94 is clear,
the board is a production board, otherwise it is a beta board.

The alpha board will likely be mistaken for a beta board.  An alpha board
was unavailible for testing.

This has been tested on the beta and production boards.

718763c474 Beagle Convert the board version detection to use the OMAP3 GPIO interface.
There is no new functionality in the change.

This change is a conversion from the using raw register access to using
the OMAP3 GPIO API described in doc/README.omap3.

9d4fc99dbd OMAP3: Fix CKE1 MUX setting to allow self-refresh
The Beagle rev Cx and Overo boards are using both SDRC CSes. The MUX
setting is needed for the second CS clock signal to allow the 2 RAM
parts to be put in self-refresh correctly. This also works on rev B
Beagle boards with 128M of RAM.

660888b7fb ZOOM2 Add serial support.
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 details of the setting of the serial gpmc setup are not available.
The values were provided by another party.

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

f62fb99941 Fix all linker script to handle all rodata sections
A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script.  Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.

However, '*(.rodata*)' by itself will result in sub-optimal section
ordering.  The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file.  This is easy to fix by using the
SORT_BY_ALIGNMENT command.

This patch has not be tested one most of the boards modified.  Some boards
have a linker script that looks something like this:

*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)

I change this to:

*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

f956fd0338 OMAP3: Beagle: Add board revision detection
With BeagleBoard revision C some HW changes are introduced (e.g. PinMUX)
which might need different software handling. For this, GPIO pin 171 (GPIO
module 6, offset 11) can be used to check for board revision. If this pin
is low, we have a rev C board. Else it must be a revision Ax or Bx board.

To handle board differences you can call function beagle_get_revision().
E.g.:

if (beagle_get_revision()) {

/* do special revision C stuff here */

}
