From 63ceb818a43391f6631efeb51fe6e0029c582497 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Tue, 19 Nov 2019 15:12:08 +0100 Subject: aspeed: Add support for the tacoma-bmc board MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Tacoma BMC board is replacement board for the BMC of the OpenPOWER Witherspoon system. It uses a AST2600 SoC instead of a AST2500 and the I2C layout is the same as it controls the same main board. Used for HW bringup.
