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.

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.

2022-11-07dm: blk: Tidy up obtaining a block device from its parentSimon Glass1-1/+27
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-11-07dm: test: Clear the block cache after running a testSimon Glass1-2/+7
Some tests access data in block devices and so cause the cache to fill up. This results in memory being allocated. Some tests check the malloc usage at the beginning and then again at the end, to ensure there is no memory leak caused by the test. The block cache makes this difficult, since the any test may cause entries to be allocated or even freed, if the cache becomes full. It is simpler to clear the block cache after each test. This ensures that it will not introduce noise in tests which check malloc usage. Add the logic to clear the cache, using the existing blkcache_invalidate() function. Drop the duplicate code at the same time. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-10-31dm: blk: Add udevice functionsSimon Glass1-1/+38
At present we have functions called blk_dread(), etc., which take a struct blk_desc * to refer to the block device. Add some functions which use udevice instead, since this is more in keeping with how driver model is supposed to work. Update one of the tests to use this. Note that it would be nice to update the functions in disk-uclass.c to use these new functions. However they are not quite the same. For example, disk_blk_read() adds the partition offset to 'start' when calling the cache read/fill functions, but does not with part_blk_read(), which does the addition itself. So as designed the code is duplicated. Signed-off-by: Simon Glass <sjg@chromium.org>

2022-09-16blk: Rename HAVE_BLOCK_DEVICESimon Glass1-1/+1
This option is fact really related to SPL. For U-Boot proper we always use driver model for block devices, so CONFIG_BLK is enabled if block devices are in use. It is only for SPL that we have two cases: - SPL_BLK is enabled, in which case we use driver model and blk-uclass.c - SPL_BLK is not enabled, in which case (if we need block devices) we must use blk_legacy.c Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is different enough from BLK and SPL_BLK that there should be no confusion. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-09-16blk: Use a function for whether block devices are availableSimon Glass1-0/+5
At present we use HAVE_BLOCK_DEVICE to indicate when block devices are available. This is a very strange option, since it partially duplicates the BLK option used by driver model. It also covers both U-Boot proper and SPL, even though one might have block devices and another not. As a first step towards correcting this, create a new inline function called blk_enabled() which indicates if block devices are available. This cannot be used in Makefiles, or #if clauses, but can be used in C code. A function is useful because we cannot use CONFIG_IS_ENABLED(BLK) to decide if block devices are needed, since we must consider the legacy block interface, enabled by HAVE_BLOCK_DEVICE Update a few places where it can be used and drop some unnecessary #if checks around some functions in disk/part.c - rely on the compiler's dead-code elimination instead.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-01-22efi_driver: EFI block driverHeinrich Schuchardt1-0/+1
This patch provides * a uclass for EFI drivers * a EFI driver for block devices For each EFI driver the uclass * creates a handle * adds the driver binding protocol The uclass provides the bind, start, and stop entry points for the driver binding protocol. In bind() and stop() it checks if the controller implements the protocol supported by the EFI driver. In the start() function it calls the bind() function of the EFI driver. In the stop() function it destroys the child controllers. The EFI block driver binds to controllers implementing the block io protocol. When the bind function of the EFI block driver is called it creates a new U-Boot block device. It installs child handles for all partitions and installs the simple file protocol on these. The read and write functions of the EFI block driver delegate calls to the controller that it is bound to. A usage example is as following: U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and exposes a handle with the block IO protocol. It calls ConnectController. Now the EFI block driver installs the partitions with the simple file protocol. iPXE uses the simple file protocol to load Grub or the Linux Kernel.

2017-08-17dm: blk: Add a generic function for block device commandsSimon Glass1-0/+12
Most block devices provide a command (e.g. 'sata', 'scsi', 'ide') and these commands generally do the same thing. This makes it harder to maintain this code and keep it consistent. We now have a block device interface which is either implemented by driver model (when CONFIG_BLK is enabled) or with a legacy interface.
