All these patches are added a support for read and write instruction for programming/reading SPI flash.
Read and Write instruction are implemented as a command line arguments for 'sf write' , 'sf read' and 'sf update' commands. Currently I have added below instructions those are commonly available on all flash types. pp - Page Program (existing one) qpp - Quad-input Page Program afr - Array Fast Read (existing one) asr - Array Slow Read dofr - Dual Output Fast Read qofr - Quad Output Fast Read diofr - Dual IO Fast Read qiofr - Quad IO Fast Read I have tested mostly of the instruction on real h/w. This entire implementation will change the current sf framework little bit but I thought these changes are worth to add. Request for all your comment, so-that I can move forward. Please let me know for any issue regarding this new implementation. Thanks, Jagan.
