Package: raspi3-firmware Version: 1.20180316-3 Severity: wishlist Tags: patch
Patch adds configuration options for the kernel command line. cma and root for now. CMA size should be configurable as the memory needed by vc4 depends on the workload. Also, the root fs should be configurable to support booting from e.g. USB.
