From 5a20ef3db28faa42dd5dc86ad75d2736bcd3da4c Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 29 Apr 2012 02:04:06 +0200 Subject: ssb: remove rev from boardinfo Previously the rev contained the revision read from the pci config space and was used as board_rev in the wireless drivers. This is wrong the board_rev is only fetched from the sprom accordingly to the open source part of the Broadcom SDK and brcmsmac. This patch removes the rev from the boardinfo structure and uses the board_rev attribute from sprom instead. This attribute is filled by PCI, PCMCIA, SDIO and SoC code.
