I have a system with 2 PowerPCs connected to the same PLB.
Each PPC has a ISOCM connected memory mapped at around 0xffff_ffff.
I download the bitfile with bootloop programs, then I open XMD,
download program for PPC0 and PPC1 in an SDRAM at different
address ranges. Run PPC 0 then 1 and everything works fine.
However; I want to get rid of the ISOCM and when I do that the
system stops working. I tried the same hardware but don't download
the bootloop, doesn't work, tried mapping 0xffff_ffff in the SDRAM
use bootloop, doesn't work.
