Hi All,

The following series updates the K3 DSP remoteproc driver to fix couple
of issues, and add the internal memory loading support on C66x DSPs.
Patches are on top of latest master branch.

Following is the patch summary:
 - Patch 1 fixes a minor issue with the existing driver
 - Patch 2 is a minor improvement to sanity check the boot addresses
   used with the DSPs within the U-Boot driver code itself.
 - Patches 3 and 4 enhance the driver to support internal memory loading
   support by re-ordering the reset sequences. Patch 3 updates the MMU
   tables, without which the memcpy results in a data abort, and patch 4
   adds the logic to the driver.

regards
Suman

Applied to u-boot-ti/next
