| H A D | locore.S | diff 222400 Sat May 28 02:21:47 MDT 2011 marcel Better support different kernel hand-offs. When loaded directly from U-Boot, the kernel is passed a standard argc/argv pair. The Juniper loader passes the metadata pointer as the second argument and passes 0 in the first. The FreeBSD loader passes the metadata pointer in the first argument. As such, have locore preserve the first 2 arguments in registers r30 & r31. Change e500_init() to accept these arguments. Don't pass global offsets (i.e. kernel_text and _end) as arguments to e500_init(). We can reference those directly. Rename e500_init() to booke_init() now that we're changing the prototype. In booke_init(), "decode" arg1 and arg2 to obtain the metadata pointer correctly. For the U-Boot case, clear SBSS and BSS and bank on having a static FDT for now. This allows loading the ELF kernel and jumping to the entry point without trampoline. |
