have read, for assembly you just need to issues a JMP to the memory location to execute it. How to do the same in C, that is the question...
P.S. This question is leading up to something great :-)
Does that code return via "ret"? If so, you'd need a call instead of a jmp, which is basically a function call.
If it does not return, I suggest you use asm volatile (" jmp 0xADDR;\n");
no, this place would be "the point of no return" (seems a little scary leaving the comfort of coreboot). :-)
But seriously, would asm volatile() be better than Ron,s solution? Also this would be executed from a payload using libpayload, is there already something written in libpayload?
