2c15513010 OMAP3 Move twl4030 power and led functions
Because twl4030 now has its own device files, move exiting
omap3 power_init_r to a new location.

power_init_r is the only function in board/omap3/common.
It initializes the twl4030 power for the board and enables
the led.

The power part of the the function is moved to twl4030_power_init in
drivers/power/twl4030.c The power compilation is conditional on the
existing config variable CONFIG_TWL4030_POWER.

The led part is moved to twl4030_led_init in the new file
drivers/misc/twl4030_led.c  The led compilation is conditional on
the new config variable CONFIG_TWL4030_LED

The directory board/omap3/common was removed because power_init_r
was the only function in it.

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.

68a531fd46 OMAP Consolidate common u-boot.lds to cpu layer.
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.

90006e9b33 OMAP3: Remove unused board-types
The board-types defined in struct omap3_sysinfo seem to be
unused. The function display_board_info() is passed
board type as an argument; which is ignored.

This patch removes all uses of board-type, related definitions
and functions.

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 */

}
