In SD spec, AU_SIZE and the value can be selected from 16KB.
But this code should be selected from 32KB.
I think right that shift (au + 3) instead of (au + 4).

This patch enhances the debug information reported
for the mmc card by parsing the extended CSD registers
obviously according to all the current specifications.
I have no HW to test eMMC 4.5 at this moment. In any case,
the patch supports JEDEC Standard No. 84-B45.
No issues on JESD84-A441 and old
16 matches
