Since our boards needs 'some' bitstream in the FPGA to become somewhat useful,
in the machine.conf I say:
MACHINE_FPGA_BITSTREAM ?= "fpga-image-miami-florida-gen-reference"
MACHINE_EXTRA_RRECOMMENDS = "${MACHINE_FPGA_BITSTREAM} ..."
This puts that into the packagegroup-base-machine RDEPENDS and hence it gets
installed on the board if you don't specify anything else.
However, I want to be able to pick alternative FPGA bitstream providers in the
image recipe. Without having to define a new machine for each and every project...
Currently, I do this by forcing packagegroup-base-machine and
packagegroup-base-distro out of the IMAGE_INSTALL list (for some obscure
reason, building packagegroup-base-distro also results in building the
reference bitstream) and then add MACHINE_EXTRA_RRECOMMENDS directly to the
IMAGE_INSTALL list, so I can set MACHINE_FPGA_BITSTREAM to whichever I'd like
to have in this image.
I was lookign for a way to have the machine configuration inject its packages
into the IMAGE_INSTALL (or similar) list, so it can easily be overridden in an
image recipe.
Bluntly putting IMAGE_INSTALL+="${MACHINE_FPGA_BITSTREAM}" into the
machine.conf might work, but doesn't "feel" quite right. But there's
apparently no other way to do this.
An alternative would be to introduce an IMAGE_INSTALL_MACHINE variable that
gets added to the PACKAGE_INSTALL variable in image.bbclass. That would allow
machines to inject their desirables into the image instead. It's a simple
patch, I've pasted it below:
diff --git a/meta/classes/image.bbclass b/meta/classes/image.bbclass
index 86a98bb..90c1c05 100644
