Hi Matt
This might be a very basic question. By porting what do you mean?. As of now
I copied the ebony bsp to different location and did changes to boot on the
custom board. Till now it was booting without any problem. Once I changed
the EBC configuration to configure some other FPGA ,bcos of which linux
booting hangs at " Now Booting the kernel ".
I commented the ioremap of RTC, and the definitions of
ppc_md.set_rtc_time = todc_set_rtc_time;
ppc_md.get_rtc_time = todc_get_rtc_time;
still the same problem. Should I hv to do something else also.
Thanking you in advance
regards
Aman
