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().

In include/blk.h, Simon suggested: ===> /* * These functions should take struct udevice instead of struct blk_desc, * but this is convenient for migration to driver model. Add a 'd' prefix * to the function operations, so that blk_read(), etc. can be reserved for * functions with the correct arguments. */ unsigned long blk_dread(struct blk_desc *block_dev, lbaint_t start, lbaint_t blkcnt, void *buffer); unsigned long blk_dwrite(struct blk_desc *block_dev, lbaint_t start, lbaint_t blkcnt, const void *buffer); unsigned long blk_derase(struct blk_desc *block_dev, lbaint_t start, lbaint_t blkcnt); <=== So new interfaces are provided with this patch.

2022-04-23disk: define nullified functions for !PARTITIONSAKASHI Takahiro
Some defconfig enables CMD_PART even if none of any partition table types (CONFIG_*_PARTITION) are enabled. This will lead to the size growth in SPL/TPL code since disk/part.c will be compiled in any way. We will change disk/Kconfig later so that CONFIG_PARTITIONS is only enabled when, at least, one of CONFIG_*_PARTITION is enabled. To make the build work (in particular, "part" command) correctly, a few functions should be defined as void functions in case of !CONFIG_PARTITIONS.

2022-04-23disk: enable function prototypes in part.h for SPL/TPLAKASHI Takahiro
Since CONFIG_[SPL|TPL]_PARTITIONS were introduced, part.h has not been updated. Due to this, while the build won't fail, some functionality may possibly break as some partition-related functions are nullified even though some partition table types are enabled for SPL/TPL.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>

Needed to support efi file protocol. The fallback.efi loader wants to be able to read the contents of the /EFI directory to find an OS to boot. Modelled after POSIX opendir()/readdir()/closedir(). Unlike the other fs APIs, this is stateful (ie. state is held in the FS_DIR "directory stream"), to avoid re-traversing of the directory structure at each step. The directory stream must be released with closedir() when it is no longer needed.
