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,
Regards, angelo
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

Add cpu related files and memory map includes. Apply the related minor changes to general coldfire architecture include files.

[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
