From: Marc Kleine-Budde Date: Sun, 9 Jan 2011 21:46:25 +0000 (+0100) Subject: can: at91_can: don't use mailbox 0 X-Git-Tag: v2.6.38-rc3~29^2~15^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9e0a2d1ca3de6e284e99ad5cae1ae33ecb74c479;p=pandora-kernel.git can: at91_can: don't use mailbox 0 Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in "AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the contents of mailbox 0 may be send under certain conditions (even if disabled or in rx mode). The workaround in the errata suggests not to use the mailbox and load it with a unused identifier. This patch implements the first part of the workaround, it updates AT91_MB_RX_NUM and AT91_MB_RX_FIRST (and the inline documentation) so that mailbox 0 stays unused.
