At that time I thought that the necessary change was small and trivial:)
As for Marek's patch, let me first explain why I implement that way,
i.e. separating disk_blk_*() from part_disk_*():
- Initially I tried to implement disk_blk_*() work for both UCLASS_BLOCK
and UCLASS_PARTITION, while this idea was rejected by Simon.
- Then, I implemented part_disk_*() with direct access to the devices,
and part_disk_*(), as helper functions, with block caching.
I thought that this approach was aligned with the implementation of
block devices (blk_[read|wirte]).
If you don't think the second point makes sense, I can agree to Marek's
approach.
Thanks,
