All this is in u-boot. E.g., start.S lives in cpu/arm920t/start.S

A while ago, Xiangfu posted a list of files containing code that the
boot loader needs.

Note that, for example, start.S does a lot more things and is in fact
very hard to read. So you want to extract only as much code as you
need for bringing up MMU, PLLs and DRAM, and ignore all the subtleties
of booting from NOR or preloaded from RAM. (You want some of this later,
but it's better to keep things simple at the beginning.)
