One of the reasons I"m working to implement paging for 32-bit mode is for our eventual change to 64-bit mode for coreboot. It's gone on the back burner for a bit as I'm doing a few other coreboot things first.
I'd love to have the help, if you have time. ron On Sun, Aug 10, 2014 at 1:02 PM, Vladimir 'φ-coder/phcoder' Serbinenko <phco...@gmail.com> wrote: > On 10.08.2014 21:06, John de la Garza wrote: >> I understand that the calling functions in 32 bit C uses the stack and >> this is why coreboot needs to use cache as RAM.
