[U-Boot] Mips: start.S Questions

21 Aug 2009


      I've figured out most of the boot process by following through the code, but
I have a few questions about start.S:
1. Calls to RVECENT and XVEVENT: what exactly do these do? RVECENT just
   branches to the first parameter f, and does nothing with the second
   parameter. Yet the first argument passed is romReserved which is defined:
...
romReserved:
       b    romReserved
Isn't that just an infinite loop?
   2. What are these for?:
...
#ifdef CONFIG_PURPLE
   /* 0xbfc00400 */
       .word    0xdc870000
       .word    0xfca70000
       .word    0x20840008....etc..
The rest seems pretty straightforward, just some processor specific things I
need to research.
