src/sys/dev/ic: pl181.c
Log Message:
The sdmmc layer will send single requests up to MAXPHYS (65536) in size.
The length field on PL180/PL181 is 16-bit, and can only support up to
65535 byte transfers.
Workaround this for now by setting the SMC_CAPS_SINGLE_ONLY flag to only
do single block (512-byte) transfers. While here set SMC_CAPS_4BIT_MODE
as well.
