; This disassembly is an analysis of the boot path up to Init_Target() ; and AI_InitIOConfig() in the special Mot C11x fw version with symbols ; (R87.2.1.03.m0 and R87.2.1.03.map), made in order to look into these ; critical board-specific init functions and in order to better prepare ; ourselves for doing similar analysis on other Compal fw versions ; for which we don't have any symbols. ; ; 2022 update: we have now also done some disassembly of Compal's buzzer ; melody player code, guided by the linker map and symbol table. 0: ea000225 b 0x89c 4: ea000825 b 0x20a0 8: ea000825 b 0x20a4 c: ea000825 b 0x20a8 10: ea000825 b 0x20ac 14: ea000825 b 0x20b0 18: ea000825 b 0x20b4 1c: ea000825 b 0x20b8 _INT_Bootloader_Start: ;
