[PATCH 00/11] Add Cortex-R52 |
Date: |

These patches add the ARM Cortex-R52. The biggest addition is
an implementation of the armv8-r MPU.
The last patch adds a machine that combines the new core with
an UART and a GIC. This machine can run many samples of
the Zephyr OS.
All information is taken from:
- ARM Cortex-R52 TRM revision r1p3
- ARM Architecture Reference Manual Supplement
-ARMv8 for the ARMv8-R AArch32 architecture profile Version A.c
Functionality that is not implemented:
- Changing between single and double precision floats
- Some hypervisor related functionality (HCR.T(R)VM,HADFSR,...)
Tobias Röhmel (11):
target/arm: Add ARM_FEATURE_V8_R
target/arm: Add ARM Cortex-R52 cpu
target/arm: Add v8R MIDR register
target/arm: Make RVBAR available for non AARCH64 CPUs

target/arm: Add ARMCacheAttrs to the signature of pmsav8_mpu_lookup
target/arm: Enable TTBCR_EAE for ARM_FEATURE_V8_R
target/arm Add PMSAv8r registers
target/arm: Add PMSAv8r functionality
target/arm: Make SPSR_hyp accessible for Cortex-R52
hw/arm: Add R52 machine
