Mark,
In your nonsec_init code, you suggest this change:
+ mrc p15, 0, r0, c1, c1, 2
movwr1, #0x3fff
- movtr1, #0x0006
- mcr p15, 0, r1, c1, c1, 2 @ NSACR = all copros to non-sec
+ movtr1, #0x0004
+ orr r0, r0, r1
+ mcr
Mark,
I finally have all this working for me on an A9 system too!
However, there were a few things that I had to change a bit.
For example, by CPUs will always come out of reset at 0x0
and I do not have the ability to set their first-fetch address to
anything else. To accommodate this, I need to
The current non-sec switching code suffers from one major issue:
it cannot run in secure RAM, as a large part of u-boot still needs
to be run while we're switched to non-secure.
This patch reworks the whole HYP/non-secure strategy by:
- making sure the secure code is the *last* thing u-boot execut
