From 0a2fcaa70ce96be6e663234072984fd2b0ffa36e Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 29 Apr 2012 02:04:08 +0200 Subject: [PATCH] bcma: add boardinfo struct This struct contains information about the board, the chip is running on. The struct is filled for PCIe devices and SoCs. This information is used by b43 and will be used by brcmsmac soon. Signed-off-by: Hauke Mehrtens Tested-by: Arend van Spriel Signed-off-by: John W.
