*************************************************************************
--Set up the MMU and enable I and D cache--
- This is the Cortex-A53 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: 0x91d000
- tcr_el3: 0x2051c
- mair_el3: 0x774400

the result report the CA training failed, we dont know which channel cause this fail.
thanks.
