On these platforms we have many cases of boards that enable device model
and GPIO support but do not enable OF_CONTROL and pass in a device tree
with the binary.  We need to bring in the platform data here as well.

Tested on Beaglebone Black.

Check for bmode before reading the boot device
to check if a serial downloader is started,
and returns UART if the serial downloader is set,
letting SPL to wait for an image if
CONFIG_SPL_YMODEM_SUPPORT is set.

This allows to load again a SPL based board
with imx_usb_loader together with a tool
such as kermit.

For some board designs, it might be useful to switch the DC-DC
clock source to something else rather the default 24 MHz, e.g.
for EMI reasons.

For this, override the mxs_power_setup_dcdc_clocksource function
in your board support files.

Example:
void mxs_power_setup_dcdc_clocksource(void)
{
    mxs_power_switch_dcdc_clocksource(POWER_MISC_FREQSEL_20MHZ);
}

If the system boots from NAND, make sure to de-assert the NAND IP
reset, otherwise the system will get stuck.
