That is good news for Issue #488 [1].

Does you patch also work for 3.12 or does it need (additional) hacks?

Or has anyone already done speed tests with 3.12 showing if it is
really needed or not?

BTW: the MMC1 interface (SD card) is running with ca. 19 MByte/s
(which fits to the 25 MHz clock and 8 data bits parallel bus).
