[PATCH] ARM: socfpga_defconfig: enable support for large block devices

[Andrey Zhizhikin]

Enable CONFIG_LBDAF, which is required by ext4 fs. This option could
hanle both ext3 and ext4, and ex4 requires this option to be enabled,
otherwise the filesystem is mounted RO mode.

CONFIG_LDBAF is turned on by default for 32-bit. So all you have to do
is remove this line.

Thanks,

Thanks a lot for clarifications here! I suspected that it was the
case, just needed a confirmation here.
Is it possible we would have this config option enabled for
socfpga_defconfig? If you would agree, then I prepare a separate patch
to have the "CONFIG_LBDAF is not set" removed.

Yes, that's what I was alluding to.
