Subject: [Qemu-trivial] DBGAUTHSTATUS register
Date: Thu, 29 May 2014 13:32:47 -0400	[thread overview]
Message-ID: <53876F3F.1060704@qnx.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 490 bytes --]

Hello,


This is not a big issue: DBGAUTHSTATUS, according to the docs, should 
exist. According to "ARM Architecture Reference Manual, ARMv7-A and 
ARMv7-R edition" (DDI0406C_b_arm_architecture_reference_manual.pdf), 
DBGAUTHSTATUS is required in all implementations. Reading it should be 
permitted, even if as RAZ only (implying no features are 
implemented/enabled).

This trivial patch defines cp14 register DBGAUTHSTATUS.


Thank you,
