Difference only in date/time of complilation and vesion info.

But I see in S2IS 1.00G disassembly:

Code: [Select]
ROM:FF8101AC dword_FF8101AC  DCD 0xDBE0                       
ROM:FF8101B0 off_FF8101B0    DCD unk_FFB090B0                 
ROM:FF8101B4 dword_FF8101B4  DCD 0xF4E0                       
ROM:FF8101B8 dword_FF8101B8  DCD 0x6EF70                     

and in platform/s2is/sub/100g/boot.c:

Code: [Select]
long *canon_data_src = (void*)0xFFB090B0;
long canon_data_len = 0xDBB0;
long *canon_bss_start = (void*)0xF4B0; // just after data
long canon_bss_len = 0x6EF70 - 0xF4B0;

Porting error?
