Subject: [PATCH 00/18] state: allow lookup of barebox state partition by Type GUID
Date: Wed, 31 May 2023 16:59:09 +0200	[thread overview]
Message-ID: <20230531145927.1399282-1-a.fatoum@pengutronix.de> (raw)

So far, we had basically three ways to reference barebox,state on block
devices:

  - On platforms with device tree, we point at a fixed partition
    described in the DT

  - On platforms without device tree, we have a custom binding that
    does a global lookup by partuuid (or a more obscure one by diskuuid).

Both are less than optimal. The first clashes with the need to use
a GPT partition for the state and the second doesn't allow relating the
UUID with an actual device for the case where e.g. both an SD-Card and
an eMMC are flashed with the same image.

This series fixes that by:

  - Supporting definition of fixed partitions that are identical to
    GPT/MBR partitions.

  - Alternatively, support pointing barebox-state backend at a
    GPT-partitioned device and the partition with the barebox-state
    Type GUID will be taken.

Ahmad Fatoum (18):
  common: partitions: decouple from EFI GUID definition
  efi: define efi_guid_t as 32-bit aligned guid_t
  cdev: fix for_each_cdev macro
  of: partition: support of_partition_ensure_probed on parent device
  of: of_path: always call of_partition_ensure_probed before resolving
  driver: add new cdev_is_partition helper
  commands: stat: remove code duplication for type info
  cdev: use more descriptive struct cdev::diskuuid/partuuid
  cdev: record whether partition is parsed from OF
  cdev: have devfs_add_partition return existing identical partition,
    not NULL
  block: parse partition table on block device registration
  common: partitions: record whether disk is GPT or MBR partitioned
  block: add cdev_is_block_(device,partition,disk) helpers
  of: export new of_cdev_find helper
  state: factor device path lookup into helper function
  cdev: use cdev::dos_partition_type only if cdev_is_mbr_partitioned
  common: partitions: efi: record type UUID in cdev
  state: allow lookup of barebox state partition by Type GUID
