From: Erik Ahlén Date: Tue, 13 Dec 2011 09:24:11 +0000 (+0100) Subject: Renamed mx2/imx27 to mxc. X-Git-Tag: v0.6.0-rc1~366 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=46cc1df722270adc0ca577b0724a4722d52543cf;p=openocd Renamed mx2/imx27 to mxc. Renamed all functions, enums, structs and defines from mx2/imx27 to mxc. This is in preparation of adding support for mx35 NFC(v2).
