2023-07-25part: eliminate part_get_info_by_name_type()Heinrich Schuchardt1-8/+2
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 Waldekranz1-0/+1
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: Use a function for whether block devices are availableSimon Glass1-47/+33
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.

This adds a filesystem which is backed by the host's filesystem. It is modeled off of sandboxfs, which has very similar aims. Semihosting doesn't support listing directories (except with SYS_SYSTEM), so neither do we. it's possible to optimize a bit for the common case of reading a whole file by omitting a call to smh_seek, but this is left as a future optimization.

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>
