I plan to use a simple 'TrustZone Monitor' with PL310(L2CC).
In non-secure, I will play a Linux-Kernel.
One problem.
1. PL310's background-operation(inv.way etc..) is executing in non-secure.
2. By secure-interrupt, dispatch to secure.
3. In secure, try to execute a write-operation to PL310' register.
May be happen 'DATA-ABORT'.
Do I must control exclusive PL310 secure and non-secure ?
Please help me.
