[PATCH v2 0/2] Fix u-boot-script packages conflict

[PATCH v2 0/2] Fix u-boot-script packages conflict

[Anton Mikanovich]

When trying to execute do_prepare_build task of u-boot-script package
for some targets 'multiple execution' occurs:

$ bitbake mc:bananapi-buster:u-boot-script:do_prepare_build mc:de0-nano-soc-buster:u-boot-script:do_prepare_build
ERROR: Detect multiple executions of do_prepare_build in /build/tmp/work/debian-buster-armhf/u-boot-script/1.1-r0
ERROR: Rerun a clean build with empty STAMPCLEAN and compare the sigdata files

This is caused by different u-boot-script packages building in the same
directory. The difference between those two output debs is dependency on
linux-image-${KERNEL_NAME}.
Now we can depend on any kernel and make u-boot-script packages equal.

[PATCH v2 1/2] dpkg: Introduce any kernel variables

[Anton Mikanovich]

To allow packages to depend on any kernel image or header package add
following variables:

linux-image-generic - any custom Isar compiled kernel image
linux-headers-generic - any custom Isar compiled headers
ANY_DISTRO_KERNEL - any upstream kernel + generic one
ANY_DISTRO_HEADERS - any upstream headers + generic ones

Provided we need this (see patch 2):

As you wrote yourself (IIRC), "generic" is used by Ubuntu. We should 
avoid name clashes. "linux-image-any"?

[PATCH v2 2/2] u-boot-script: Depend on any kernel package

[Anton Mikanovich]

Make u-boot-script depend on any installed kernel version to fix
package build conflict for the machines with different KERNEL_NAME
but same distro and arch.

Did you also check if we could drop the dependency? If not, I will do 
that before we settle of this. Would be simpler if it works.

Checked: We can drop this series in favor of "u-boot-script: Drop 
runtime dependency on a kernel".

[Anton Mikanovich]

Thanks for checking. This is much better solution, so the the original 
fix can be dropped.
