[PATCH 0/5] Handoff bloblist from previous boot stage

[Raymond Mao]

This patch set depends on another series:
"[PATCH v3 00/14] Support Firmware Handoff spec via bloblist".

This patch set implements Qemu-Arm platform custom functions to retrieve
the bloblist (aka. Transfer List) from previous loader via boot arguments
when CONFIG_OF_BOARD option is enabled and all boot arguments are compliant to
the register conventions defined in the Firmware Handoff spec v0.9.

Qemu-Arm platform custom function will load the FDT from the bloblist if it
exists.
Otherwise it fallbacks to get the FDT from the specified memory address.

If a platform vendor wish to have different behaviors for loading bloblist
or FDT from the previous boot stage, it is required to implement the custom
functions board_bloblist_from_boot_arg() and board_fdt_blob_setup().

Raymond Mao (5):
  bloblist: add API to check the register conventions
  qemu-arm: Get bloblist from boot arguments
  bloblist: Load the bloblist from the previous loader
  fdt: update the document and Kconfig description
  qemu-arm: get FDT from bloblist
