Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20140804' into staging

target-arm queue:
 * Set PC correctly when loading AArch64 ELF files
 * sdhci: Fix ADMA dma_memory_read access
 * some more foundational work for EL2/EL3 support
 * fix bugs which reveal themselves if the TARGET_PAGE_SIZE
   is not set to 1K
