Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20150907' into staging

target-arm queue:
 * cleanup to use g_new() and friends
 * support semihosting in A64
 * add SMBIOS support to mach-virt
 * remove hw_error() usages
 * fix bug in the AArch32:AArch64 register mapping
 * add a second PCI memory window in highmem on virt board
 * fix bug in arm_excp_unmasked()
 * add i.MX31 SoC
 * remove restriction on handling affinity values in virt board
