[edk2] [PATCH edk2-platforms v1] Platform/ARM: Declare FVP Generic Timer Frame #1 as Non-secure
Posted by AlexeiFedorov 7 years, 5 months ago 
From: Alexei Fedorov <alexei.fedorov@arm.com>

Programming Reference for Base FVPs describes 2 Generic Memory-mapped
Timer frames with Non-secure access permitted to frame #1.
However ACPI GTDT lists both timer frames #0 and #1 with
Secure Timer flag being set in GTx Common Flags field:
 #define FVP_GTX_COMMON_FLAGS
   (GTX_TIMER_SAVE_CONTEXT | GTX_TIMER_SECURE)
Declaring both timer frames as Secure prevents OS running
in Non-secure state from accessing Generic Timer frame #1.

This patch fixes the above issue by removal of FVP_GTX_COMMON_FLAGS
and adding two FVP_GTX_COMMON_FLAGS_S and FVP_GTX_COMMON_FLAGS_NS
definitions used for Secure frame #0 and Non-secure frame #1
accordingly.

Notes:
    v1:
    - remove FVP_GTX_COMMON_FLAGS                                 [Alexei]
    - define FVP_GTX_COMMON_FLAGS_S and FVP_GTX_COMMON_FLAGS_NS   [Alexei]
    - use FVP_GTX_COMMON_FLAGS_S for timer frame #0 and           [Alexei]
          FVP_GTX_COMMON_FLAGS_NS for frame #1
