This series add minimum features required by Spec v3 to support UHS-I cards.

Since v7:
- we keep the 'capareg' property, this simplify a lot the series
- the ZynqMP uses the datasheet CAPAREG
- reset R-b/A-b

Note: https://www.google.com.ar/search?q=sdhci_imx0+caps show various console
      output with i.MX6 capareg value of 0x0377c800 

Since v6:
- rebased on upstream
- included spec v3 qtest back

Since v5:
- addressed Alistair reviews
- dropped "abstract generic-sdhci"
- dropped Linux Device Tree names
- split qtests in another series
- change the bcm2835 minimum blocksize to 1KB (Andrew Baumann)
- added Alistair R-b
- based on Alistair work:
  - add SD tunning sequence via Host Control 2 to use UHS-I cards
  - add CMD/DAT[] fields in the Present State (used in next series
    to switch card voltage)

based on Alistair work:
- add SD tunning sequence via Host Control 2 to use UHS-I cards
- add CMD/DAT[] fields in the Present State (used in next series
  to switch card voltage)

Since v4 ("SDHCI: add qtests and fix few issues"):
- spec_version default to v2 (current behaviour)
- addressed Alistair review (no v1, tell user about valid version)

Since v3:
- no change, but split back in 2 series, 1st part is "SDHCI: housekeeping v5",

Since v2:
- more detailed 'capabilities', all boards converted to use these properties
- since all qtests pass, removed the previous 'capareg' property
- added Stefan/Alistair R-b
- corrected 'access' LED behavior (Alistair's review)
- more uses of the registerfields API
- remove some dead code
- cosmetix:
  - added more comments
  - renamed a pair of registers
  - reordered few struct members

Since v1:
- addressed Alistair Francis review comments, added some R-b
- only move register defines to "sd-internal.h"
- fixed deposit64() arguments
- dropped unuseful s->fifo_buffer = NULL
- use a qemu_irq for the LED, restrict the logging to ON/OFF
- fixed a trace format string error
- included Andrey Smirnov ACMD12ERRSTS write patch
- dropped few unuseful patches, and separate the Python polemical ones for later

From the "SDHCI housekeeping" series:
- 1: we restrict part of "sd/sd.h" into local "sd-internal.h",
- 2,3: we somehow beautiful the code, no logical changes,
- 4-7: we refactor the common sysbus/pci qdev code,
- 8-10: we add plenty of trace events which will result useful later,
- 11: we finally expose a "dma-memory" property.
From the "SDHCI: add a qtest and fix few issues" series:
- 12,13: fix registers
- 14,15: boards can specify which SDHCI Spec to use (v2 and v3 so far)
- 15-20: HCI qtest

Regards,

Phil.
