rockchip: block: blk-uclass: add bounce buffer flag to blk_desc

2023-10-24T07:55:17+00:00

Currently bounce buffer support is enabled for all block devices
when available. Add a flag to blk_desc to enable only on demand.

get_desc() can be useful outside blk-uclass.c. Let's change it to
an API and make it externally visible.

blk: Add bounce buffer support to read/write operations

2023-08-22T19:17:53+00:00

Some devices have limited DMA capabilities and require that the
buffers passed to them fit specific properties. Add new optional
callback which can be used at driver level to indicate whether a
buffer alignment is suitable for the device DMA or not, and
trigger use of generic bounce buffer implementation to help use
of unsuitable buffers at the expense of performance degradation.

ide: Avoid preprocessor for CONFIG_LBA48

2023-04-27T17:51:06+00:00

Use IS_ENABLED() instead for all conditions. Add the 'lba48' flag into
struct blk_desc always, since it uses very little space. Use a bool so
the meaning is clearer.

ide: Correct use of ATAPI

2023-04-27T17:51:06+00:00

The use of atapi_read() was incorrect dropped. Fix this so that it will
be used when needed. Use a udevice for the first argument of atapi_read()
so it is consistent with ide_read().

This requires much of the ATAPI code to be brought out from behind the
existing #ifdef. It will still be removed by the compiler if it is not
needed.

Add an atapi flag to struct blk_desc so the information can be retained.

dm: blk: Tidy up obtaining a block device from its parent

2022-11-07T23:24:30+00:00

This function now finds its block-device child by looking for a child
device of the correct uclass (UCLASS_BLK). It cannot produce a device of
any other type, so drop the superfluous check.

Provide a version which does not probe the device, since that is often
needed when setting up the device's platdata.

Also fix up the function's comment.
