Bugs
====
1. For IPECamera, shall we limit DMA packet size to xdma_packet_lenght register
additionally to size of memory page?
High Priority (we would need it for IPE Camera)
=============
1. Serialize access to the registers across applications
2. Protect kmem_entries in the driver using spinlock
3. CMake build system
Normal Priority (it would make just few things a bit easier)
===============
1. Implement software registers (stored in kernel-memory)
2. Support FIFO reads/writes from/to registers
3. Provide OR and AND operations on registers in cli
4. Support writting a data from a binary file in cli
5. Use bus-addresses instead of physcial addresses for DMA
Low Priority (only as generalization for other projects)
============
1. XML configurations describing registers (and DMA engines?)
2. Access register/bank lookups using hash tables
