Re: [U-Boot] [PATCH] mmc: omap: handle controller errors properly

According to OMAP3 TRM, when the controller reports certain errors, driver must perform a software reset. This is done by setting a bit in SYSCTL and waiting it to clear:

• SRC on command timeout (CTO)
• SRD on data errors (DTO, DCRC and DEB)

This fixes a problem seen on OMAP3 pandora board with some cards that won't work with a message printed multiple times: timedout waiting on cmd inhibit to clear

Code loosely based on Linux omap_hsmmc driver.

Most excellent! Pali, can you try this on N900 and see if that helps out the problem you were having as well?

Andy, I'll give this a spin through the boards I've got here but I'd like this to go, via your tree, into u-boot/master assuming all goes well.
