The chip tundra doesn't support 8 bit data width transfer.
It's going to be emulated writing first in register of
the slave indicating the width

Added Cesar's driver for VME.

better if it looks like one

the IRQ subscription is done using the VME driver
handling of the IRQ, request and response is done using
the etherbone library

if need be

since KBUILD_EXTMOD and KBUILD_EXTRA_SYMBOLS compilations
options don't work, I have create the one manually,
it seems to work

	Now it uses three windows:
	1) CR/CSR
	2) WB Control, 24A access
	3) WB Data,    32A access

	  clones from  the repo

API 1&2 were the same; merged.
API 0 renamed to 1

It allows to use from a vme master eb commands (e.g. eb-ls) over the vme interface.
It follows the philosophy of pci-wb. So far only reading eb commands are supported.
The development is in a test phase, for that reason there are hardcode values and paths.

Main files:
vme_wb.*: register the kernel module and creates two VME windows, the first for the
          setting of the CSR/CR parameters in the vme slave, and second for data
          communication.
Module.symvers: it is needed for the correct compilation of the module sice it uses functions
                from wishbone.ko and vmebus.ko.
scripts for inserting and removing the module.

This merges subdirectory support for sdbfs. We are using it in FMC
mezzanine eeproms

This is a trivial patch, swapping two blocks and adding a few
lines, so to allow "position=" and "maxsize=" to be used for
subdirectories.

This allows to reserve space for a new SDBFS image to be added
at a later time.

This commit doesn't change actual output for gensdbfs, but it prepares
for recursive scanning of directories. This is a separate commit to ease
my own debugging.

External projects copying this directory will most likely have
their own "include" directory, but not always "include/linux".
This, use -I../include to they can place sdb.h in there without
modifying their copy of this Makefile.
