Hi Namjae,
I scanned over your changes to enable GP partitions, and while I

The affected fields are ext_csd.raw_erased_mem_count and

Hi Andrei,
I saw in one of the community threads that you also have a patch ready for
supporting Auto CMD23 for SDHCI. Can you share the same with us? I would like
to take a look at your patch first before deciding
Dear Group,
This is the third version of the CMD23 plumbing and host driver support

Changes:
1) CMD23 support (used for features such as reliable writes) is decoupled
from general multiblock trans through use of a quirk for affected cards.
2) Newer Sandisk MMC products are
Conditional add/remove quirks for MMC and SD.

predefined multiblock transfers if these are supported.
Before this patch set, all multiblock transfers look like (for example)
