Hi, arm experts,
We want to use ARCH32 mode in secure EL1, I see some descriptions in ARMv8 Arch Reference Manual about Secure EL1 ARCH32 mode as follows:
One is the VBAR(secure), it is mapped to VBAR_EL3, the other is SCTLR (secure), it is mapped to SCTLR_EL3.
That means secure EL1 and EL3 share VBAR and SCTLR?
Moreover, in SCTLR ARCH32 mode (G4.2.114 in ARMv8 Reference Manual), write M(bit 0) only means EL1 and EL0 stage 1 address translation enabled,
If EL1 and EL3 share SCTLR, how can I config it in ARCH32 mode?
That really confuse me, wait for your help, thank you!
