Subject: [PATCH v1 0/8] soc/fsl/qbman: Enable Kexec for DPAA1 devices

Most DPAA1 devices do not support a soft reset which is an issue if
Kexec starts a new kernel. This patch series allows Kexec to function
by detecting that the QBMan device was previously initialized.

The patches fix some issues with device cleanup as well as ensuring
that the location of the QBMan private memories has not changed
after the execution of the Kexec.

Roy Pledge (8):
  soc/fsl/qbman: Rework QBMan private memory setup
  soc/fsl/qbman: Cleanup buffer pools if BMan was initialized prior to
    bootup
  soc/fsl/qbman: Cleanup QMan queues if device was already initialized
  soc/fsl/qbman: Use index when accessing device tree properties
  soc/fsl/qbman: Fix drain_mr_fqni()
  soc/fsl/qbman: Disable interrupts during portal recovery
  soc/fsl/qbman: Fixup qman_shutdown_fq()
  soc/fsl/qbman: Update device tree with reserved memory
