From cf8bb114418e7b96f1d18d4e38418ccf8eec957f Mon Sep 17 00:00:00 2001 From: Vitor Soares Date: Fri, 17 Apr 2026 15:42:04 +0200 Subject: board: toradex: aquila-am69: add remoteproc firmware pre-loading Some use cases require remoteproc firmware to be loaded before Linux boots. Introduce rprocsemmcboot and rproc_fw_binaries to load the remoteproc cores from U-Boot, relying on the TI k3_rproc framework which already handles the secure firmware variants, firmware loading, and proper initialization. The firmware binaries are expected to be present in the eMMC rootfs under /lib/firmware/. To activate, run rprocsemmcboot or add it to bootcmd: bootcmd=run rprocsemmcboot; bootflow scan -b The upstream U-Boot does not yet have the remoteproc DT nodes enabled for the Aquila AM69, making firmware loading fail. Marking as pending waiting for remoteproc enabling, which could happen along with the OF_UPSTREAM migration.
