how does crt0.base move to c_start.S. I did not find any reference to c_start.S from crt0.base or any other .inc files included in crt0.base

Hi,
Could anyone tell me what are the .inc files found in the LinuxBIOS
source?
Are these generated from the C code (for the sdram code I could see an association between the .c and corresponding .inc) and how ?
The .inc files are assembly language files that "stack up" or include, in order, on top of crt0.base. These execute first, and eventually move the C-code (and decompress it if necessary) to RAM, ending at c_start.S, which jumps to the C-code. The .inc files do things that are necessary as a prelude to running C, which needs RAM (ie, a stack).
Each .inc file must jump around its data, it is expected to execute top to bottom and flow to the next file included below it.
