2023-08-22disk: dos: Infer MBR partition sector size from underlying drive sector sizeMarek Vasut
Block devices with 4k sectors imply the MBR sectors are also 4k instead of regular 512B. Avoid hard-coding the 512B sector size and isntead read the current block device sector size from it, and if the sector size is larger than 512B, use the block device sector size.

2023-08-22disk: Move part_create_block_devices() to blk uclassMarek Vasut
Move part_create_block_devices() to blk uclass and unexpose the function. This can now be internal to the block uclass. Signed-off-by: Marek Vasut <[email protected]>
2023-08-22disk: Switch part_blk_*() functions to disk_blk_*()Marek Vasut
The behavior of the part_blk_*() functions is now identical to disk_blk_*() functions, switch the former to the later. Signed-off-by: Marek Vasut <[email protected]>
2023-08-22disk: Extend disk_blk_part_validate() with range checkingMarek Vasut
Check whether access is out of bounds of the partition and return an error. This way there is no danger of esp. write or erase outside of the confines of partition. Signed-off-by: Marek Vasut <[email protected]>
2023-08-22disk: Handle partition to block device offset conversionMarek Vasut
Convert the read/write/erase offset from one within a partition to one within a block device, to correctly access the data on the block device for both write and erase operations. Signed-off-by: Marek Vasut <[email protected]>
2023-08-22disk: Simplify disk_blk_{write, erase}() using blk_{write, erase}()Marek Vasut
These two functions are basically identical, just call the blk_*() functions from disk_blk_*() functions. The only difference is that the disk_blk_*() functions have to use parent block device as the udevice implementing block device operations. Add documentation on what those functions really do. The documentation is not wrong even though it likely does look that way. The write/erase functions really do not take into account the partition offset. This will be fixed in the next patch. Signed-off-by: Marek Vasut <[email protected]>
2023-08-22disk: Simplify disk_blk_read() using blk_read()Marek Vasut
The disk_blk_read() can be simplified using blk_read(), the only things which needs to be handled are the read offset based on the partition properties, and the block device ops which are coming from the parent udevice, not the partition udevice. The later is currently not implemented correctly as far as I can tell, since the current code extracts block device descriptor from the parent udevice which is OK, but extracts block device operations from the partition udevice, which does not seem OK. Switching to the blk_read() fixes that too. The dev_get_blk() usage is simplified using UCLASS_PARTITION check. Add non-confusing documentation what this really does.

2023-08-22disk: Drop always true conditional checkMarek Vasut
if (device_get_uclass_id(dev) == UCLASS_PARTITION) is always true, because this disk_blk_read() function calls dev_get_blk() above and checks its return value for non-NULL. The dev_get_blk() performs the same device_get_uclass_id(dev) check and returns NULL if not UCLASS_PARTITION. Drop the duplicate check. Signed-off-by: Marek Vasut <[email protected]>

2023-07-25part: eliminate part_get_info_by_name_type()Heinrich Schuchardt
Since commit 56670d6fb83f ("disk: part: use common api to lookup part driver") part_get_info_by_name_type() ignores the part_type parameter used to restrict the partition table type. omap_mmc_get_part_size() and part_get_info_by_name() are the only consumers. omap_mmc_get_part_size() calls with part_type = PART_TYPE_EFI because at the time of implementation a speed up could be gained by passing the partition table type. After 5 years experience without this restriction it looks safe to keep it that way. part_get_info_by_name() uses PART_TYPE_ALL. Move the logic of part_get_info_by_name_type() to part_get_info_by_name() and replace the function in omap_mmc_get_part_size().

2023-04-05cmd: blkmap: Add blkmap commandTobias Waldekranz
Add a frontend for the blkmap subsystem. In addition to the common block device operations, this allows users to create and destroy devices, and map in memory and slices of other block devices. With that we support two primary use-cases: - Being able to "distro boot" from a RAM disk. I.e., from an image where the kernel is stored in /boot of some filesystem supported by U-Boot. - Accessing filesystems not located on exact partition boundaries, e.g. when a filesystem image is wrapped in an FIT image and stored in a disk partition.

2022-09-16blk: Rename HAVE_BLOCK_DEVICESimon Glass
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 <[email protected]>
2022-09-16blk: Use a function for whether block devices are availableSimon Glass
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.
