Hi
Declare ERASE capability so we can use filesystems with the discard option and the fstrim tool.
I totally agree with you that information about such capabilities should be exposed but maybe it would be wiser to use DT instead of hardcoding it? I mean a WiFi device won't support erase functionality... http://lists.infradead.org/pipermail/linux-arm-kernel/2011-October/068210.html
