Add a recipe to build and package jailhouse image for am62xx-evm. new image will
be named as tisdk-jailhouse-image. jailhouse recipe will also package overlay
used for jailhouse.
Add functionality to change kernel and u-boot source via MACHINE_FEATURES for
jailhouse. so if MACHINE_FEATURES:append = " jailhouse" is added to local.conf
different recipe for kernel (linux-ti-extras) and u-boot (u-boot-ti-extras) will
be used.
So for jailhouse build for am62xx-evm user will have to add
MACHINE_FEATURES:append = " jailhouse" to local.conf and then start a jailhouse
build with MACHINE=am62xx-evm bitbake -k tisdk-jailhouse-image.

This would conflict with all the other places PREFERRED_PROVIDERs are being
set. In other words, if "jailhouse" in MACHINE_FEATURES is not set, you are
forcing everyone into "ti-staging" trees, which is not always the case!
What about "bb.org" trees, or "next", or "mainline" or any downstream ones?
based on your review, i tried changing PREFERRED_PROVIDERs in
tisdk-jailhouse-image.bb using:
if 'jailhouse' in d.getVar('MACHINE_FEATURES',True).split():
d.setVar('PREFERRED_PROVIDER_virtual/kernel', 'linux-ti-extras')
d.setVar('PREFERRED_PROVIDER_virtual/bootloader', 'u-boot-ti-extras')
d.setVar('PREFERRED_PROVIDER_u-boot', 'u-boot-ti-extras')
i added above code to do_configure:append() . also tried adding above
code inside a custom function "do_change_provider()" and used "addtask
do_change_provider" inside tisdk-jailhouse-image recipe. but either the
build failed or the preferred_providers didn't change. can you help with
this or suggest any alternate method we can use? We want to change
preferred_providers if MACHINE_FEATURES has jailhouse and not have a
conflict with other places as you mentioned.
Thanks
