make reset a rel jump to 0xfffffff0 - (sizeof entry16). Then put entry 16 right before 0xfffffff0. Entry16 code turns on 32-bit mode and then jumps to the real start of the linuxbios image -- which can now be anywhere in the flash image. I could use this now, as could others.
Sounds pretty good!
it sounded good to me too :-)
sadly, it appears that 0xffe0000 is not enabled at hardware startup.
Stefan, what makes sense to do for this problem?
One option is to grow this idea a bit: have the 32-bit mode enable right below 0xfffffff0, but include in that a flash enable. Then it would work.
By far the simplest thing to do is make it possible to move c_payload around, say to 0xfffe0000
