AT697 PCI: abort whhen a peripheral PCI system detected
DRVMGR: added return error descriptions
GRTIMER: added to GPTIMER driver

GRTIMER is compatible with GPTIMER, however the GPTIMER driver
does not support the extended features of GRTIMER.
AT697PCI: fix PCI cfg writes
AMBAPP: updated PnP IDs database with SPWTDP
GR-RASTA-TMTC: updated for new version

From this driver's point of view the major new thing is that the
GRPCI peripheral PCI bridge has been updated to GRPCI2, the second
version. This means that both Big and Little Endian systems are now
supported and autodetected on runtime.

The PCI frequency is used as AMBA frequency of the GR-RASTA-TMTC.
GR-RASTA-IO: updated for new version

From this driver's point of view the major new thing is that the
GRPCI peripheral PCI bridge has been updated to GRPCI2, the second
version. This means that both Big and Little Endian systems are now
supported and autodetected on runtime.
SPWTDP: added SpW Time Distribution Protocol driver

This driver supports mainly device discovery and
interrupt handling.
LIBPCI: removed unused code
GRSPW: Fix incorrect register defines - presently functionally inconsequential
SPWTDP: updated driver against updated HW spec
RMAP: added new asynchonous interface
LIBPCI: make pci_print print slot0 on bus0
SPWTDP: add driver registration to drvmgr
LEON PCI: fix for PCI host bridge driver CFG space access
GRSPW_PKT: Add support for Interrupt-codes

Update: Daniel Hellstrom updated SpW-IRQ implementation accoring to
        changes in hardware register layout and features.
SPWTDP: clear interrupt status on interrupt
