Add basic support for the DENX M53EVK board. Currently supported is:
MMC (incl. booting)
NAND (incl. booting)
Ethernet, I2C, USB, SATA, RTC.

Please keep this list (and all similar ones) sorted.  Thanks.

Are the parens needed / useful here?

It's sorted, by CPU first and by board name seconds. I think it's easier to 
search it that way, what do you say?

No, not anymore

It looks like there is something wrong here: The last line connects OTG.OC to
EIM_D21.ALT6, but the line before sets GPIO_18 as GPIO7[13] instead of setting
EIM_D21 as OTG.OC.

And here you set PKE without PUE, which means that PAD_CTL_100K_PD will have no
effect on the pad, i.e. the keeper will be enabled, not a 100-k PD.

According to http://www.denx-cs.de/doku/?q=m53pinout , USB_OTG_OC is on ball D7
(i.e. GPIO_18), and ball V3 (i.e. EIM_D21) is not on the SoM connector.

So can you clarify what's going on with this signal? Is it handled by software
as a GPIO, and EIM_D21 is just tied high or low on the SoM to make the hardware
controller not complain about a false OC detection?

Best regards,
Benoît

Yes, the OTG OC is handled by GPIO.

So should "mxc_iomux_set_input(MX53_USBOH3_IPP_IND_OTG_OC_SELECT_INPUT, 1);" be
dropped or not?

Applied to u-boot-imx, thanks.

Benoit's 24/25 will then fix the remaining issue - I am applying also that.
