linux 4.11-1~exp1 FTBFS on armel.  I spent a little while modularising
some things that were unnecessarily built-in, but the image size will
still be very close to the current limit of 2 MiB.  If it grows beyond
this we'll lose support for many QNAP models.

It should be possible to reduce the image size quite a bit by changing
NAND drivers to modules.  I don't know if initramfs-tools is smart
enough to include these drivers in the initramfs where needed.  It
would certainly be necessary to add those drivers to the mtd-modules
udeb.

It may also be possible to reduce the image size by modularising more
cryptographic stuff.  The big piece there is cryptomgr
(CONFIG_CRYPTO_MANAGER2), which is directly or indirectly selected by
most other cryptographic options.  So this might be impossible.  It
also might require changes to cryptsetup to get the right modules
included in the initramfs.

I'm going to leave further decisions on the size limit and
configuration to you.  If armel/marvell breaks again and stays broken
then I'm going to have to disable it.

Ben.
