Subject: target/cortex_m: Add Realtek Real-M200 and M300
X-Git-Url: https://review.openocd.org/gitweb?a=commitdiff_plain;h=3182a1398a02a930396bd0192bda2a9ed3dacd6f;hp=05ee88915520d1dd82da94a016a9374a1f3a8129;p=openocd.git

target/cortex_m: Add Realtek Real-M200 and M300

These cores are advertised as M23 and M33 compatible, but are identified
by the Realtek implementor id.  These cores are found on the RTL872xD
family, at least.

Raw CPUIDs:
Real-M200 (KM0): 721cd200
Real-M300 (KM4): 721fd220
