Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20160304' into staging
target-arm queue:
 * Correct handling of writes to CPSR from gdbstub in user mode
 * virt: lift maximum RAM limit to 255GB
 * sdhci: implement reset
 * virt: if booting in Secure mode, provide secure-only RAM, make first
   flash device secure-only, and assume the EL3 boot rom will handle PSCI
 * bcm2835: use explicit endianness accessors rather than ldl/stl_phys
 * support big-endian in system mode for ARM
 * implement SETEND instruction
 * arm_gic: implement the GICv2 GICC_DIR register
 * fix SRS bug: only trap from S-EL1 to EL3 if specified mode is Mon
