Choosing ONFI timings when ->set/get_features() calls are supported by the NAND chip is a matter of reading the chip's ONFI parameter page and telling the chip the chosen mode (between all of the supported ones) with ->set_feature(). Add a check on whether the chip "acked" the timing mode or not. This can be a problem for NAND chips that do not follow entirely the ONFI specification. These chips actually support other modes than "mode 0", but either: 1/ do not update the timing mode register once a timing mode has been selected. or 2/ do not support the TIMING_MODE featured and thus do not require users to change the timing mode at all. These issues will be addressed in another patch that will add the feature to overwrite NAND chips features within the parameter page, from the NAND chip driver.
