[PATCH v7 RESEND 0/8] Handoff bloblist from previous boot stage

[Raymond Mao]

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 BLOBLIST option is enabled and
all boot arguments are compliant to the register conventions defined
in the Firmware Handoff spec v0.9.

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().

V5:
Drop [PATCH v4 8/9] fdt: update the document and Kconfig description.
V6:
Drop [PATCH v5 8/8] fdt: get FDT from bloblist.
V7:
Fixed CI pipeline failures.

Raymond Mao (8):
  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
  dts: OF_HAS_PRIOR_STAGE should depend on !BLOBLIST
