Block Size Register bits [14:12] is SDMA Buffer Boundary, it is missed in register write, but it is needed in SDMA transfer. e.g. it will be used in sdhci_sdma_transfer_multi_blocks to calculate boundary_ variables. Missing this field will cause wrong operation for different SDMA Buffer Boundary settings. Fixes: d7dfca0807 ("hw/sdhci: introduce standard SD host controller") Fixes: dfba99f17f ("hw/sdhci: Fix DMA Transfer Block Size field")
Is this change stable-worthy? Not understanding the implications, so have to ask :) Thanks, /mjt
