libubootenv is a replacement for u-boot-fw-utils. It is hardware-independent and provides fw_printenv and fw_setenv tools that are full compatible with the ones provided by U-Boot. A library is provided to access the environment from an own application. License is LGPL-2.1 and this allow to link the library to proprietary code. The user of the tools should install the configuration file "fw_env.config", as he is already used to with u-boot-fw-utils. The configuration file is compatible with u-boot-fw-utils. A full discussion about issues on current u-boot-fw-utils can be read on U-Boot's ML at: http://u-boot.10912.n7.nabble.com/SWUpdate-U-Boot-environment-library-dependency-tt340530.html#none (From OE-Core rev: 325a8dec3c24723e02c8c7a0b416321adc7a5717) Signed-off-by: Stefano Babic <sbabic@denx.de> 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.
