Hi, all
This patch is about adding codes to turn on CCI compatible with all platforms, A15
x4, and big.LITTLE, etc.
With this patch, a Secure vector table is installed, with which the
data abort for accessing CCI on boards where it doesn't exist can be
captured and handled.
There are open issues with the code, somebody can clarify:
1. Is the default secure vector table being used in other palce? I
didn't find. But if yes, I should restore secure vector table.
2. When return from data abort exception, I added two 'nop' instruction.
Without them, the instruction 'cmp r4, #0xba' seems not function
correctly. That's really tricky.
- I tried to use exception return instruction 'subs pc, lr, #8'. It doesn't help.
Thanks.
