Remove unused code. The padconf code has been replaced with the
generic pinctrl(4) driver and intc(4) now attaches using the device
tree.

If you use sys/param.h, you don't need sys/types.h

Remove unused table driven omgpio bits.

remove remaining parts of the table driven approach to attaching edma

Remove now unused definitions for drivers that have been converted to
use the fdt.

Add missing parts of the tiic driver.

Add gpio(4) support for omap3/4 and am335x.

Feedback by patrick and syl, tested by syl on BeagleBoard and BBB.

After factorizing armv7_machdep code here is an effort to factorize all
the code present in omap/omap.c imx/imx.c and sunxi/sunxi.c

All this code looks quite the same, so we move it in a generic armv7/armv7.c

This is a step closer to only one kernel for all armv7 boards.

Move mmc base address registers workaround where it belongs.

Add edma driver. This driver add support for am335x edma3 controller.

With some more work, it will allow us to speed-up ommmc driver.

ok patrick@.

Enable the eMMC on the BeagleBone Black.

In the future, we shouldn't have one port port ARM SoC, that's just
ridiculous. This is the first step for a common and generic ARM port
for ARMv7 SoCs.
