[U-Boot] [YBA] mx28evk.h CONFIG_EHCI_MXS_PORT0 power?

[Jonathan Ben Avraham]

Dear colleagues,
When I configure mx28evk with CONFIG_EHCI_MXS_PORT0 instead of the 
default CONFIG_EHCI_MXS_PORT1, and run on an i.MX28 EVK PCB REV D, and 
do "start usb" at the prompt, then ehci_set_usbmode(0) (to set host 
mode) is called but there is no 5V output on the micro-usb connector and 
so the attached storage device is not detected.

When I use CONFIG_EHCI_MXS_PORT1 the storage device receives 5V and U-Boot 
detects it.

In Linux 3.13.9 with "dr_mode = host" in the usb0 DTS config, the 
micro-usb connector receives 5V and the storage device is detected, so I 
know that the hardware is configured correctly and works.

Where should I look to debug the power configuration for usb0?
TIA,

  - yba
