This a suffix series for http://u-boot.10912.n7.nabble.com/PATCH-v4-00-36-sf-Add-common-probe-and-ext... 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.
Changes for v5: - Re-implemented write command log - not trying to discover the fastest write - Added SPI RX/TX operation modes - SPI flash parts are moved into sf_params.c file - Added QUAD_IO_FAST read support - Discovred the read dummy_cycles based on configured read cmd - Added set QEB support for macronix flash - Enabled quad read/write cmd support for macronix flash Changes for v4: Changes for v3: Changes for v2: - none
