igep00x0, beagle and omap3evm: fixing bug at prcm_init
Commit 73eb46434657c8c2c9e7c9146406031fc4d124ce changed get_cpu_rev()
to be a generic function for all omap 3 based boards, to remove
duplicated code. As a side effect, the behavior changed for beagle and
omap3evm when the board is based on 37XX, returning a different value
then CPU3430_ES2, causing a bug at prcm_init.
The fix is already applied for overo, as you can see from commit 24b8b7f41a83540433024854736518876257672c, changing the index calculation
to behave correctly with all board revs. This patch only applies the
same fix for the other omap 3 based boards that could be affected.

The abort() is a dummy function that is not being used, and the

xloader: Panda - fix ROM OTG boot path
When the OMAP 4 on Panda sees that USB OTG external power is present,
it changes the boot flow in the ROM to try to boot via that before
trying MMC1. If it isn't satisfied, it falls through to try MMC1.
Without this patch, under those conditions X-Loader is unable to
update the DPLL as it needs to do during dram initialization, because
the EMIF never goes idle allowing the shadow update mechanism to
apply the new settings.
It therefore loops for a long period waiting to confirm the settings
applied and boot is hung (with LEDs off, so the device looks OFF).
This patch re-enables EMIF idle which was previously commented out with
"No IDLE: BUG in SDC" to allow the new DPLL settings to apply.
With the patch against http://gitorious.org/x-loader HEAD the Panda is
able to boot from either USB OTG power applied or DC Jack power OK.
Note that I saw peak current during boot of 650mA, higher than the
500mA allowed by USB. It may go higher with other peripherals enabled
or trying to use USB host on Panda.

Adding support for saving build objects in a separated directory.
This patch basically ports the same functionality already available at u-boot,
and can be used in two ways:
1) Add O= to the make command line
'make O=/tmp/build board_config'
'make O=/tmp/build ift'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make board_config'
'make ift'
Similar to u-boot, setting 'O=' at the command line will override the BUILD_DIR
environment variable.
If you use none of above methods, the build will happen localy, as before.

* Rebase to correctly apply against the main Makefile after the signGP merge
