37 * Define the resource table entries for all PRU cores. This will be
38 * incorporated into corresponding base images, and used by the remoteproc
39 * on the host-side to allocated/reserve resources. Note the remoteproc
40 * driver requires that all PRU firmware be built with a resource table.
41 *
42 * This file contains an empty resource table. It can be used either as:
43 *
44 * 1) A template, or
45 * 2) As-is if a PRU application does not need to configure PRU_INTC
46 * or interact with the rpmsg driver
