For anyone who's interested, here's an update to the MMC code LinusJust to make sure I've understood this correctly. SGIO takes a number of memory locations and fills these with data from a continous stream of data from the card? I.e. only the local memory locations need special handling. No seeking on the card? And any "gaps" where data is not wanted is handled by upper layers?
recently merged. Essentially, I've added SG support to the MMCI
primecell driver.
