From f5953610bf9198a585e39c8074ef9dea1106da9c Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Thu, 31 May 2018 15:10:21 +0530 Subject: [PATCH] cmd: fpga: Reorder the arguments parsing code This patch modifies the arguments parsing code by parsing based on requested operation for fpga loadfs and then parses the most common/basic args for other fpga load commands. This makes it easy for new command extensions or additions especially the commands with more args.
