New platform Coldfire cpu MCF52259

[Henrik Berg]

Hi,

I'm working on a port on eLua to Coldfire MCF52259. It is going well
and I may be ready with something presentable in a couple weeks.

Some questions:

What shall the platform name be? It's a Coldfire v2 core, the family
is MCF5225x and I have a M52259EVB Evaluation Board to test it on.

The 'board' name will be M52259EVB but do you have any pref o the platform name.

Thanks!

Great news! Thank you. I was planning a ColdFire port myself, but
didn't have the time. Are you using the CodeSourcery toolchain?

Platform naming in eLua follows closely the CPU manufacturer's line of
products. An example: lpc24xx and lpc 288x. If you go to the NXP site,
you'll find a lot of CPUs under the LPC24xx family and a few (but more
than one) CPUs in the LPC288x family. Your platform should be named
following a similar reasoning. I'll take a look at the ColdFire
product tree and come up with a suggestion as soon as I have some time
for this.

Best,
Bogdan

After looking here :

http://www.freescale.com/webapp/sps/site/taxonomy.jsp?nodeId=0162468rH3YTLC00M95448

It looks as though all MCUs on that page (your included) share the
same common core, the only differences being at peripheral level
(memory sizes included). If this is indeed the case, I'd name the
platform "mcf52" or maybe "cfv2mcu" (ColdFire V2 MCU), but probably
"mcf52".

Best,
Bogdan
