In preparation of heterogeneous machines, remove knowledge of the
target endianness in generic hw/ code. Move it to the machine level.

Philippe Mathieu-Daudé (13):
  qemu/bswap: Introduce ld/st_endian_p() API
  hw/virtio/virtio-access: Use the ld/st_endian_p() API
  target/arm/ptw: Use the ld/st_endian_p() API
  hw/mips: Pass BlCpuCfg argument to bootloader API
  hw/mips: Add cpu_is_bigendian field to BlCpuCfg structure
  tests/tcg/plugins: Use the ld/st_endian_p() API
  hw/xtensa/xtfpga: Remove TARGET_BIG_ENDIAN #ifdef'ry
  hw/xtensa/xtfpga: Replace memcpy()+tswap32() by stl_endian_p()
  exec/memory_ldst_phys: Introduce ld/st_endian_phys() API
  hw/virtio/virtio-access: Use ld/st_endian_phys() API
  hw/pci/pci_device: Add PCI_DMA_DEFINE_LDST_END() macro
  hw/pci/pci_device: Introduce ld/st_endian_pci_dma() API
  hw/net/tulip: Use ld/st_endian_pci_dma() API
