Needs a patch comment. What's an MC13224V? Maybe:
The MC13224V is a FreeScale ARM7TDMI based IEEE® 802.15.4 platform for
Zigbee and similar low-power wireless applications. It uses PIP
(Platform In Package) technology, and boots from ROM which shadows
code from serial flash into RAM.

THose ircapture and irmask values are the defaults for irlen = 4 so
you shouldn't specify them. ("ircapture" should only be specified
if the chip doesn't conform to the JTAG spec in that way.)

There are no variants of the arm7tdmi, so don't specify that.

Line too long. Also, with no MMU in this chip, "-work-area-virt" is
inappropriate. (Right, no MMU?)

That's specific to your work environment; don't include it
in a file that's intended to be general purpose.
