From dc8ecdd3a3fccf73fcb07711cde064ce5727f9d1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 1 Sep 2014 23:11:06 +0200 Subject: [PATCH] bcma: move bus struct setup into early part of host specific code MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This change is important for SoC host. In future we will want to know chip ID (needed for early MIPS boot) before doing cores scanning. Signed-off-by: Rafał Miłecki Acked-by: Hauke Mehrtens Signed-off-by: John W.
