Add support for an --offset argument when defining a partition. Many SoCs require that boot partitions be located at specific offsets. Prior to this argument, most WKS files were using the --align attribute to specify the location of these fixed partitions but this is not ideal because in the event that the partition couldn't be placed in the specified location, wic would move it to the next sector with that alignment, often preventing the device from booting. Unlike the --align argument, wic will fail if a partition cannot be placed at the exact offset specified with --offset. Changes in V2: * Fixed a small typo that prevented test_fixed_size_error from passing (From OE-Core rev: 897aaff8961f7fe83634a3b0b94e19b43aea5857) Signed-off-by: Joshua Watt <JPEWhacker@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> (cherry picked from commit 467f84e12b96bc977d57575023517dd6f8ef7f29) Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
