      Fully initialise essential control registers · 18f2efd6
      David Cunado authored 
      

This patch updates the el3_arch_init_common macro so that it fully
initialises essential control registers rather then relying on hardware
to set the reset values.

The context management functions are also updated to fully initialise
the appropriate control registers when initialising the non-secure and
secure context structures and when preparing to leave EL3 for a lower
EL.

This gives better alignement with the ARM ARM which states that software
must initialise RES0 and RES1 fields with 0 / 1.

This patch also corrects the following typos:

"NASCR definitions" -> "NSACR definitions"

      Exit early if size zero for cache helpers · 3ec5204c
      Soby Mathew authored 
      

This patch enables cache helper functions `flush_dcache_range`,
`clean_dcache_range` and `invalidate_dcache_range` to exit early
if the size argument specified is zero

      Fix issues in FWU code · ee05ae16
      Soby Mathew authored 
      

This patch fixes the following issues in Firmware Update (FWU) code:

1. The FWU layer maintains a list of loaded image ids and
   while checking for image overlaps, INVALID_IMAGE_IDs were not
   skipped. The patch now adds code to skip INVALID_IMAGE_IDs.

2. While resetting the state corresponding to an image, the code
   now resets the memory used by the image only if the image were
   copied previously via IMAGE_COPY smc. This prevents the invalid
   zeroing of image memory which are not copied but are directly
   authenticated via IMAGE_AUTH smc.

      plat: Hikey960: fix the CPU hotplug · 0aedca71
      Leo Yan authored 
      

In CPU off callback function, the old code uses the function
hisi_test_pwrdn_allcores() to check if all CPUs in cluster have been
powered off and if it's valid then power off the whole cluster. But the
function hisi_test_pwrdn_allcores() only maintains the different power
states only for CPU suspend/resume flow, so it cannot return correct
states for CPU on/off flow.

This patch is to change use hisi_test_cpu_down() to check if all CPUs
have been powered off, so that can power off the whole cluster properly
when all CPUs in cluster have been hotplugged off.
