[Pkg-raspi-maintainers] Bug#951744: raspi-firmware, please provide a mechanism to add parameters to the kernel command line.

Package: raspi-firmware

Hi,

Sometimes it is necessary to add parameters to the kernel command line, for example rpi.gpio requires "iomem=relaxed".

In the current setup there is no good way to do this, editing cmdline.txt directly will result in changes being overwritten on the next kernel upgrade. Editing /etc/kernel/postinst.d/z50-raspi-firmware is likely to result in conflicts when upgrading.
