This patch series adds the mipsel architecture and a QEMU machine to Isar to
support legacy projects wanting to migrate to Debian (the mipsel architecture
and Malta reference board are supported with both stretch and buster). The
last patch is optional but desirable: it would add the qemumipsel-stretch
configuration to the ci_build chain.

ChangeLog:
  * v2: add qemumipsel-buster configuration
  * v1: initial submission (targeting qemumipsel-stretch)

Cedric Hombourger (9):
  image.bbclass: introduce KERNEL_FILE (defaults to vmlinuz)
  start_vm: append kernel arguments specified in QEMU_KARGS
  recipes-devtools/*-apt: add support for the mipsel architecture
  recipes-kernel/linux: add support for the mipsel architecture
  start_vm: add mipsel to the list of supported architectures
  meta-isar: add the qemumipsel machine
  ci_build: add qemumipsel-stretch to build targets
  meta-isar: add qemumipsel-buster configuration
  ci_build: add qemumipsel-buster configuration to build targets
