Subject: mips32: Removed Unnecessary JTAG Queue Flush
X-Git-Url: https://git.gag.com/?a=commitdiff_plain;h=e1466df54d8ddd6800f8df2f9e0d2f1dd646cb20;p=fw%2Fopenocd

mips32: Removed Unnecessary JTAG Queue Flush

jtag_execute_queue() is executed as a part of mips_ejtag_drscan_32().
No need for this to be done before - removed for optimisation.
