Hi,
this series adds MMU support for ARM and ARM64. We will need those
patches for cache coherency.
I was able to fully consolidate ARM and ARM64 MMU driver code.
I did a lot of testing, but I might have overseen some things -- please
test and review carefully.
Tested on a Jetson TK1 and QEMU ARM64.
Thanks!
Ralf
since v2:
- add additional () around SCTLR_MMU_CACHES
- add memory_barrier() after writing to the comm_region
- proper (de-)initialisation of the MMU for ARM's linux-loaders
since v1:
- place the linux-loader patch before enabling the MMU
- use CONFIG_INMATE_BASE instead of the symbol __inmate_base
- Adress Jan's comments on register naming. Use now real register
names and alias them.
