[PATCH 00/18] boot: improve cdev alias and blspec support

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Building on past top of past bootscan and cdev alias infrastructure in
next, enable the following:

   - Favoring entries in GPT XBOOTLDR partition and EFI system
     partitions, like we already do for MBR XBOOTLDR partition

   - Allow state backend and other DT bindings to point at a
     barebox,bootsource node to allow same state DT description
     to work across different boot media

Ahmad Fatoum (18):
  cdev: make cdev_find_child_by_gpt_typeuuid external
  cdev: constify cdev_find_child_by_gpt_typeuuid's guid_t pointer
    argument
  partition: efi: respect DPS_TYPE_FLAG_NO_AUTO flag
  blspec: iterate over all XBOOTLDR partitions
  blspec: support GPT XBOOTLDR partition
  blspec: collect bootloader spec entries from ESP
  cdev: alias: add support for partition links
  cdev: do not dereference partname for non-partitions
  cdev: use common cdev_free helper internally
  cdev: implement devfs_create_link in terms of devfs_create
  misc: storage-by-uuid: consider only first diskuuid match
  misc: storage-by-uuid: prepare for generalizing to different aliases
  misc: storage-by-uuid: rename to storage-by-alias
  misc: storage-by-alias: switch over to using cdev aliases
  misc: storage-by-alias: add support barebox,bootsource
  misc: storage-by-alias: register as link to main cdev
  cdev: constify cdev_readlink argument
  cdev: follow links in cdev_find_child_by_gpt_typeuuid
