MX8 DDR Stress Test Version: ER14
Built on Mar 27 2020 12:28:23
*************************************************************************
-Set up the MMU and enable I and D cache-
- This is the Cortex-A35 core
- Check if I cache is enabled
- Enabling I cache since it was disabled
- Push base address of TTB to TTBR0_EL3
- Config TCR_EL3
- Config MAIR_EL3
- Enable MMU
- Data Cache has been enabled
- Check system memory register, only for debug
- VMCR Check:
- ttbr0_el3: 0x13d000
- tcr_el3: 0x2051c
- mair_el3: 0x774400
- sctlr_el3: 0xc01815
- id_aa64mmfr0_el1: 0x101122
- MMU and cache setup complete
