[PATCH v2 0/2] Zynq7000 series device configuration driver

[Patrick Gauvin]

v2 Change Summary (primarily from Chris's feedback):

SLCR:
- Clean up register accesses.
- Add mask for FPGA clock resets.

Device Config:
- Remove DMA buffer static global.
- Remove register map as an argument (only one instance ever).
- Remove bitfile length related code.
- Add bitfile header check.
- Default the write behavior to writing an entire bitfile.
- Add BIN file header check in default write mode.
- Added ioctl to switch write mode to to unrestricted.
- Remove non-symbolic '| 1' for DMA source and destination addresses.
- Use RTEMS system events instead of semaphores for interrupt waits.
- Fix PCAP init failure when the PL is already programmed.

General:
- More documentation and error values.

These changes do not include a secure loading check. The check I saw was
to use the PCAP to read the PART_SECURED bit in the internal STAT register
after the PL is programmed. I still need to test if that sort of access is
allowed when a secure bitfile is loaded. For now I just have warnings in
comments that secure loading is not supported.

Please let me know if I've missed anything or you spot anything new.
