[U-Boot] [PATCH 1/1 V2] add support for mcf5307 cpu

[Angelo Dureghello]

Hello Jason and all,
i started to work to rewrite the patch.

Starting from mcf532x/cpu.c, i am not sure this is the right place to add MCF5307.

1) On "checkcpu", mcf5307 don't have ccm->cir where to read mask/ver.
2) About "do_reset", here also mcf5307 don't have MMAP_RCM, memory map and reset procedure are different. 
3) In general, as memory map, mcf5307 is much more similar to some mcf52x2 cpu. This is the reason why i thought to treat it as a separate family.
Looking here:
http://www.freescale.com/webapp/sps/site/taxonomy.jsp?code=68KCFV3
seems Freescale also treat it as the only cpu of the MCF530X family.

I can still go ahead, but cpu.c should have a great #ifdef CONFIG_MCF5307 to handle separately this cpu. How do you think i should proceed ? 

regards
angelo
