+
+ccree specific items
+a.k.a stuff fixing for this driver to move out of staging
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1.  Move to using Crypto Engine to handle backlog queueing.
+2.  Remove synchronous algorithm support leftovers.
+3.  Separate platform specific code for FIPS and power management into separate platform modules.
+4.  Drop legacy kernel support code.
+5.  Move most (all?) #ifdef CONFIG into inline functions.
+6.  Remove all unused definitions.
+7.  Re-factor to accomediate newer/older HW revisions besides the 712.
+8.  Handle the many checkpatch errors.
+9.  Implement ahash import/export correctly.
+10. Go through a proper review of DT bindings and sysfs ABI
+11. Sort out FIPS mode: bake tests into testmgr, sort out behaviour on error, 
+    figure if 3DES weak key check is needed
+
+Kernel infrastructure items
+a.k.a stuff we either neither need to fix in the kernel or understand what we're doing wrong
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+1. ahash import/export context has a PAGE_SIZE/8 size limit.  We need more.
+2. Crypto Engine seems to be built for HW with hardware queue depth of 1, we have 600++.
