Staging: VME: Update TODO file

				TODO

				====

API

===

Master window broadcast select mask

-----------------------------------

API currently provides no method to set or get Broadcast Select mask. Suggest

somthing like:

	int vme_master_bmsk_set (struct vme_resource *res, int mask);

	int vme_master_bmsk_get (struct vme_resource *res, int *mask);

Interrupt Generation

--------------------

Add optional timeout when waiting for an IACK.

CR/CSR Buffer

-------------

The VME API provides no functions to access the buffer mapped into the CR/CSR

space.

Mailboxes

---------

Whilst not part of the VME specification, they are provided by a number of

chips. They are currently not supported at all by the API.
