[PATCH v4 0/9] Handoff bloblist from previous boot stage

[Raymond Mao]

This patch set depends on another series:
"[PATCH v5 00/11] Support Firmware Handoff spec via bloblist".

This patch set adds/adapts a few bloblist APIs and implements Arm arch
custom function to retrieve the bloblist (aka. Transfer List) from
previous loader via boot arguments when OF_BOARD option is enabled and
all boot arguments are compliant to the register conventions defined
in the Firmware Handoff spec v0.9.

FDT library function will load the FDT from the bloblist if it exists.
Otherwise it fallbacks to get the FDT from the board custom function.

If an arch wishes to have different behaviors for loading bloblist
from the previous boot stage, it is required to implement the custom
function xferlist_from_boot_arg().

Raymond Mao (9):
  bloblist: add API to check the register conventions
  bloblist: check bloblist with specified buffer size
  bloblist: refactor of bloblist_reloc()
  arm: armv7: save boot arguments
  arm: armv8: save boot arguments
  arm: Get bloblist from boot arguments
  bloblist: Load the bloblist from the previous loader
  fdt: update the document and Kconfig description
  fdt: get FDT from bloblist
