2025-07-03disk: efi: expose the part_get_gpt_pte() helper functionJavier Martinez Canillas

2025-06-02include/ide.h: Cleanup usageTom Rini
At this point in time, <ide.h> provides the IDE_BUS macro and the function prototype for ide_set_reset, which is used with IDE_RESET. The only files which should include this header are the ones that either use that macro or that function. Remove <blk.h> from <ide.h> and remove <ide.h> from places which do not need it.

2024-11-20disk: expose partition type flagsCaleb Connolly
GPT partition tables include two bytes worth of vendor defined attributes, per partition. ChromeOS and Qualcomm both use these (with different encoding!) to handle A/B slot switching with a retry counter. Expose these via the disk_partition struct so that they can be parsed by the relevant board code. This will be used on Qualcomm boards to determine which slot we're booting on so that we can flash capsule updates to the correct one.

We can just return the const char* pointer directly.
