From 029093a302c9a66b74bec46285a179abd122a40a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=81lvaro=20Fern=C3=A1ndez=20Rojas?= Date: Sun, 21 Feb 2021 10:00:18 +0100 Subject: bmips: add new target MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This target has full device tree support, thus reducing the number of patches needed for bcm63xx, in which there's a patch for every board. The intention is to start with a minimal amount of downstream patches and start upstreaming all of them. Current status: - Enabling EHCI/OHCI on BCM6358 causes a kernel panic. - BCM63268 lacks Timer Clocks/Reset support. - No PCI/PCIe drivers. - No ethernet drivers.
