Ross Burton 9d2fd91844 bitbake: utils: also use mmap for SHA256 and SHA1, for performance
md5_file() uses a mmap() window to improve performance when hashing files, so
refactor the code and do the same for SHA1 and SHA256.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
