Help needed to understand code

[Shubhangi Jadhav]

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

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.
