Description

Added API to set default SPI mode (single/quad) for SDHC. Compile time default set to single mode to maintain backwards compatibility.

Some feedback below - take it or leave it. This looks good, just some thoughts on a potentially cleaner diff for this.

On the version number files - See #937. I still need to get around to an automatic workflow for updating them, but don't delete them in the meantime

I think it might be cleaner to come in "over the top" and avoid adding the extra enum value. A direct getter/setter to the state variable would work, so your call from diskio.c would look like:

MXC_SDHC_Lib_Write(sector, (void *)buff, count, MXC_SDHC_Get_DataWidth())

Usually you're not gonna change your data width more than once at run-time, so a mechanism for setting the default value might be better implemented as a build-time option. Users can use the setter API you've exposed on initialization.

This would let us avoid these modifications to sdhc_lib.c, since the data width is already an arg to the SDHC functions

[EricB-ADI]

That is what is set as in diskio.c. The point of doing this extra step was to not break the API if someone uses it directly. Since Get/Set default data width doesn't really do more than allow us to get it at the higher level. It is a little Awkard that you set it and then have to pass it anyway. I am fine deleting those modifications though.
