Convert cp15 crn=9 registers (mostly cache lockdown) to the new scheme. Note that this change makes OMAPCP cores RAZ/WI the whole c9 space. This is a change from previous behaviour, but a return to the behaviour of commit c3d2689d when OMAP1 support was first added -- subsequent commits have clearly accidentally relegated the OMAPCP RAZ condition to only a subset of the crn=9 space when adding support for other cores.

Convert the cp15 crn=6 registers to the new scheme. Note that this includes some minor tidyup: drop an unnecessary underdecoding of op2 on OMAPCP cores, and only implement the pre-v6 c6,c0,0,1 IFAR on the 1026 and not on the other ARMv5 cores, which didn't have it.

Convert the cp15 crn=7 registers to the new scheme. Note that to do this we have to distinguish some registers used on the ARM9 and ARM10 from some which are ARM1176 only. This is because the old code returned a value of 0 but always set the Z flag (by clearing env->ZF, since we store the Z flag in CPUState inverted). This is inconsistent with actual ARM CPU behaviour, which only sets flags for reads to r15 and sets them based on the top bits of the result. However it happened to work for the two common use cases for cp15 crn=7 reads: * On ARM9 and ARM10 the cache clean-and-test operations are typically done with a destination of r15 so that you can do a "loop: mrc ... ; bne loop" to keep cleaning until the cache is finally clean; always setting the Z flag means this loop terminates immediately * on ARM1176 the Cache Dirty Status Register reads as zero if the cache is dirty; returning 0 means this is correctly implemented for QEMU Since the new coprocessor register framework does the right thing of always setting flags based on the returned result for reads to r15, we need to split these up so that we can return (1<<30) for the ARM9/ARM10 registers but 0 for the ARM1176 one. This allows us to remove the nasty hack which always sets Z. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

We RAZ/WI the entire block of crn=10 registers. Note that this actually covers not just the implementation-defined TLB lockdown registers but also a number of v7 VMSA memory attribute registers which we would need to implement to support TEX remap. We retain the previous QEMU behaviour in this conversion, though. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

In commit 1bba0dc9 cpu_reset() was renamed to cpu_state_reset(), to allow introducing a new cpu_reset() that would operate on QOM objects. All callers have been updated except for one in target-mips, so drop all implementations except for the one in target-mips and move the declaration there until MIPSCPU reset can be fully QOM'ified.

Make cpu_arm_init() return a QOM ARMCPU, so that we don't need to obtain an ARMCPU through arm_env_get_cpu() in machine init code. This requires to adjust the inclusion site of cpu-qom.h and in turn, forward-looking, to homogenize its include order. cpu_init() must still return a CPUARMState for backwards and cross-target compatibility, so adjust the cpu_init macro.

Add support for ARM BE8 userspace binaries. i.e. big-endian data and little-endian code. In principle LE8 mode is also possible, but AFAIK has never actually been implemented/used. System emulation doesn't have any useable big-endian board models, but should in principle work once you fix that. Dynamic endianness switching requires messing with data accesses, preferably with TCG cooperation, and is orthogonal to BE8 support.

This patch replaces the ARM_FEATURE_VFP3 test when reading MVFR registers with a test for a new feature flag ARM_FEATURE_MVFR, and sets this feature for all ARMv6K cores (ARM1156 is not a v6K core, yet supports MVFR; qemu does not support ARM1156 at this time.) MVFR0 and MVFR1 were introduced in ARM1136JF-S r1p0 (ARMv6K, VFPv2) and are present in ARM1156T2F-S (non-v6K), ARM1176JZF-S, ARM11MPCore and newer cores.
