In order to reduce the kernel size we disable some unused
filesystems and the respective xattr, posix acl.
The second patch removes the mem=64M hardcoding for collie.
The third one updates collie's CFI driver to the last version.

Revert to the 3.2 pre-yocto settings.
Removed yaffs, reiserfs, btrfs, most xattr and posix options.
Make NFS modular.

Surely rare today, the SL-5000D has only 32MB ram.
Remove historical setting used for mtd-ram.

+Subject: [PATCH] mtd: cfi_cmdset_0001.c: add support for Sharp LH28F640BF NOR
-Tested on Zaurus SL-5500 (Collie) 2x16 on 32 bit bus
+This family of chips was long ago supported by the pre-cfi driver.
+CFI code tested on several Zaurus SL-5500 (Collie) 2x16 on 32 bit bus.
+
+Function is_LH28F640BF() mimics is_m29ew() from cmdset_0002.c
Buffer write fixes as seen in 2007 patch c/o
