| * sunxi: Remove mmc DMA supportHans de Goede2014-07-06-134/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the dma descriptors on the stack, and then exits while the dma transfer is in progress, so the dma engine is reading stack memory which at that point may be re-used. So far we've gotten away with this by luck, but recent u-boot changes have shifted the stack start address by 16 bytes, which combined with dma alignment now exposes this problem. Since we end up just busy waiting for the dma engine anyway, this commit fixes things by simply removing the dma code, resulting in smaller bug-free code.

Since mmc->tran_speed is either the maximum allowed speed, or the preliminary value, that is be not yet set to registers, the actual timeout, taken by the controller, based on its clock settings, may be much longer than expected, based on mmc->tran_speed value. In particular it happens at early initialization stage, when typical value of mmc->tran_speed is 20MHz or 26MHz, while actual clock setting, configured in the controller, is 400kHz.

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.
