From: Fabio Estevam fabio.estevam@freescale.com

On the mx53loco board with mc34708 PMIC it is necessary to turn on VUSB regulator so that the mx53 USBH1 PHY receives the 3.3V voltage.

Tested by inserting a USB pen drive in the upper USB slot (USBH1) and then issued the commands:

usb start

usb info

,which correctly detected and printed the USB pen drive information.

1.7.1

FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information.

The kernel uses this data to distinguish between Dialog versus mc34708 based boards, and also to distinguish between revA and revB of the mc34708 based boards.
