From: Zachary T Welch Date: Fri, 4 Dec 2009 00:47:49 +0000 (-0800) Subject: add flash/nor/{tcl.c,imp.h} from flash/flash.c X-Git-Tag: v0.4.0-rc1~127 X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=3cb0b56005059314c8d09d2f8574042a4352dab4 add flash/nor/{tcl.c,imp.h} from flash/flash.c Moves the top-level 'flash' command handlers into flash/nor/tcl.c, with flash/nor/imp.h providing an internal implementation header to share non-public API components. --- diff --git a/src/flash/flash.c b/src/flash/flash.c index d16949da4c..b21838cfaa 100644 --- a/src/flash/flash.c +++ b/src/flash/flash.c @@ -120,39 +120,6 @@ int flash_driver_protect(struct flash_bank *bank, int set, int first, int last) return retval;
