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
