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.

Thanks,
Jagan.
