While the current jimtcl does not consider this an error, the Tcl dodekalogue states that strings terminate at the second double quote character (see https://www.tcl.tk/man/tcl/TclCmd/Tcl.htm#M8). These syntax errors were caught by tclint v0.2.5 (https://github.com/nmoroze/tclint): ``` tclint tcl/chip/st/spear/spear3xx_ddr.tcl | grep "syntax error" ``` Change-Id: I2763d93095e3db7590644652f16b7b24939d6cae Signed-off-by: Noah Moroze <noahmoroze@gmail.com> Reviewed-on: https://review.openocd.org/c/openocd/+/8281 Tested-by: jenkins Reviewed-by: Tomas Vanek <vanekt@fbl.cz> Reviewed-by: Antonio Borneo <borneo.antonio@gmail.com>
