From 24890f11980eb70d835ca7e0b00d32284d8f546c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20Bie=C3=9Fmann?= Date: Tue, 12 Apr 2011 23:25:41 +0000 Subject: avr32: add ATAG_BOARDINFO MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds a new ATAG_BORADINFO to U-Boot. This tag is intended to hand over the bd->bi_board_number to the linux kernel for early stage board information like a board revision or other kind of board specific decisions necessary before the linux peripherial drivers are up.
