[U-Boot] [PATCH v6 00/12] sf: Add Extended read and quad read/write commands support

[Jagannadha Sutradharudu Teki]

This a suffix series for
http://u-boot.10912.n7.nabble.com/PATCH-v4-00-36-sf-Add-common-probe-and-extended-quad-read-write-cmds-support-td163949.html
for adding extended read and quad read/write commands support.

Concept:
"Implementation will discover the fastest command by taking the supported
commands from flash and a controller. Controller supported commands will always been a priority."

The above concept is changed in this series as couple of reviews from earlier ones.
- Implementation concept will apply on read commands.
- As we have two write commands as of now – so this series is not trying to
  discover the fastest write command
- The respective command modes are given to the controller driver side as a form of
  SPI RX/RX operation modes - so sf definitions will not be part of SPI driver side.

Testing branch:
$ git clone git://git.denx.de/u-boot-spi.git
$ cd u-boot-spi
$ git checkout -b master-quad origin/master-quad

REQUEST FOR ALL SPI CODE CONTRIBUTORS/USERS, PLEASE TEST THESE CHANGES
W.R.T YOUR HW IF POSSIBLE.

Please let me know for any issues/concerns/questions.

Changes for v4:
Changes for v3:
Changes for v2:
        - none
