mmc_write.c: Make mmc_berase do 32bit safe 64bit math

2015-06-18T20:11:41Z

We want to see if the requested start or total block count are unaligned. We discard the whole numbers and only care about the remainder. Update the code to use div_u64_rem here and add a comment.

mmc: Split mmc struct, rework mmc initialization (v2)

2014-03-24T10:58:56Z

The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou

mmc: don't support write & erase for SPL builds

2013-09-20T15:58:55Z

For SPL builds this is just dead code since we'll only need to read. Eliminating it results in a significant size reduction for the SPL binary, which may be critical for certain platforms where the binary size is highly constrained. Signed-off-by: Paul Burton Acked-by: Pantelis Antoniou
