This causes ARM Linux kernel to hang during initialization for ARMv7 CPUs. However that has so far been hidden by another emulation bug where the cp15 c1 system control register has an invalid reset value for the emulated ARMv6 and ARMv7 processors indicating an earlier processor revision instead and thus making QEMU run the MMU emulation in ARMv5 mode. This patch series fixes the access protection emulation in the ARM MMU emulation (1) and introduces correct cp15 c1 system control register values for the ARM1136, Cortex-A8 and Cortex-A9 cores (2,3).
