Hi Jason and all,
i am really interested to bring mcf5307 inside u-boot. But still waiting for your feedback/help on my comments below.
Let me know your comments.
Many thanks,
Hi, angelo,
Could you please try as seperate MCF530X family but send out the complete patchset? You previous patch seems only include the new files. Thanks.
Regards, Jason

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.
- On "checkcpu", mcf5307 don't have ccm->cir where to read mask/ver.
- 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

[Jin Zhengxiong-R64188] Could you please try to merge the 5307 cpu to mcf532x as we already have two ColdFire V3 boards here(We can try to rename the mcf532x to such \ as mcf53xx later for less confuse). You can keep the immap_5307.h and m5307.h for the 5307 cpu. All the other files are similar with the files for the two V3 \ boards except the
cpu_init.c file.
Thanks.
Jason
