From da87dd7bd70f71ceaf9ff40d7cdb8394a7dc4bf5 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Sat, 2 Nov 2013 16:03:50 +0000 Subject: sun4m: Add FCode ROM for TCX framebuffer Upstream OpenBIOS now implements SBus probing in order to determine the contents of a physical bus slot, which is required to allow OpenBIOS to identify the framebuffer without help from the fw_cfg interface. SBus probing works by detecting the presence of an FCode program (effectively tokenised Forth) at the base address of each slot, and if present executes it so that it creates its own device node in the OpenBIOS device tree. The FCode ROM is generated as part of the OpenBIOS build and should generally be updated at the same time.
