Cannot say much, but generally won't happen for very long. - This has lowest priority and doing other projects, won't be able to continue within reasonable amount of time. I will be very glad if you would continue this patch, as I will not be able to contribute that. BTW. Adding Maxime to CC, since he will be most interested in this as newest stmmac maintainer. Apologies for missing you earlier.
