[SLOF] [PATCH v3 00/22] Generic virtio 1.0 with block and network support

[Nikunj A Dadhania]

Following patch series enables virtio 1.0 support in SLOF.
Currently, two drivers are supported virtio-blk and virtio-net.

Patches are organised in following order:

    01-12: Generic fixes, code improvements and re-organization
    13-19: Enables generic virtio 1.0 functionality
    20-21: Converts virtio-blk and virtio-net drivers to 1.0
       22: Enables modern devices (device ids > 1041)

Changelog:
v2:
* split patch 08 to different patches
* Set local-mac-address only once
* rename virtio_{read,write}64 to virtio_pci_{read,write}64
* Remove q_size magic
* Introduce cpu_to_modern{16,32,64} and vice versa
* Use cpu_to_le32 in place of bswap32
* Consistently use int type and 0/-1 as return
* Not required to set running = 0 in error case

v1:
* Patch re-organisation as suggested by alexey
* Separated out coding style changes and code re-organization
* Feature negotiation now sets and checks FEATURES_OK bit
* Added virtio_get_status for feature negotiation
* Added missing notify_off_mul in SLOF virtio_device structure
* virtio-net - net_hdr_size was missing at one place
* squashed all the api conversion to one single patch
* Introduced and enabled virtio_parse_capabilities in 
  one single patch. Also, disabled is_modern until the 
  driver is ready.

ToDo:
* Convert virtio-scsi and virtio-9p drivers
