[PATCH] arm: bcm2835: enable proc and sysfs in defconfig

[Thomas Petazzoni]

For some reason, support for proc and sysfs is currently disabled in
the bcm2835_defconfig, even though those filesystems are quite
essential even for very basic Linux userspace. As most defconfig have
them enabled by default, enable them as well in bcm2835_defconfig.

How silly of me; I had this as part of a local change for testing, but
hadn't made a patch to add it to the defconfig upstream.

Applied to bcm2835's for-3.8/defconfig branch. Thanks.

    Hm, I don't see where are you enabling them... So I miss something?

WBR, Sergei

Yes:

config PROC_FS
        bool "/proc file system support" if EXPERT
        default y

config SYSFS
        bool "sysfs file system support" if EXPERT
        default y

Those options are enabled by default. So, when there's nothing in the
defconfig file to disable them, they are enabled.
