Bug Description
u-boot is able to define a complete pin-muxing setting.
On OMAP4 today, we rely on x-loader for this purpose.
So we shall either:
1) deactivate pin-muxing setting for omap4, or
2) or use it and ensure we have the latest pin-mux updates integrated
Option 1 was used here: http://
Today for example, the pin-mux for GPMC_A22 is not properly set in u-boot, resulting in non-functional BT feature.
For this specific BT issue, the correct pin-mux is described in this x-loader patch (included into x-loader-omap4 package):

(If we ever want to get rid of x-loader as a separate body of code, I'd rather we arrange for the pin settings to be matching in the two source trees.)
