Use only the single block transfer method.

multiple block transfers.

---help---
|
|
SDIO driver will use D0 Busy signalling to detect Write Complete.
|
|
This option when selected, will enable the MMCSD driver to use the
|
|
underlying SDIO drivers implementation of the SD specification's
|
|
D0 Busy signalling to detect Write Complete. This will avoid
|
|
potentially very long (600Ms+) busy waiting in the MMCSD driver.
|
|
|
|
To implement D0 Busy signalling, the underlying driver must
|
|
be capable of switching the D0 GPIO to be a rising edge sensitive
|
|
interrupt pin. It must then, condition that pin to detect the rising edge
|
|
on receipt of SDWAIT_WRCOMPLETE in the SDIO_WAITENABLE call and
|
|
return it back to regular SDIO mode, when either the ISR fires or pin is
|
|
found to be high in the SDIO_EVENTWAIT call.

Some hardward needs to be informed of the selected blocksize and the
|
|
number of blocks. Others just work on the byte stream. This option
|
|
enables the block setup method in the SDIO vtable.
