Subject: [PATCH v2 0/2] MIPS: BMIPS: Improved early panic support

Hi Thomas,

This patch series adds support for cfe_die() which can be used during
early platform initialization when we do not yet have a valid DTB to
infer an earlycon console from. This is useful while bringing up new
platforms/DTBs as well.

Thanks!

Changes in v2:

- ensure that we do not break multi-CPU builds by reading the CPU's PrID
  to perform the appropriate XKS01 disabling before handing over to CFE

Florian Fainelli (2):
  MIPS: CFE: Add cfe_die()
  MIPS: BMIPS: Utilize cfe_die() for invalid DTB
