Ok, here is the mapping i'm currently using . For the E000'0000 -
E0ff'ffff area i have to program PMM1 with "non-standard" values.
/* PCI mapping:
**
** PLB addr PCI memory addr
** --------------------- ---------------------
** 0000'0000 - 7fff'ffff <--- 0000'0000 - 7fff'ffff
** 8000'0000 - Bfff'ffff ---> 8000'0000 - Bfff'ffff
** E000'0000 - E0ff'ffff ---> 0000'0000 - 00ff'ffff
**
** PLB addr PCI io addr
** --------------------- ---------------------
** e800'0000 - e800'ffff ---> 0000'0000 - 0001'0000
**
*/
I'm also thinking about splitting the 8000'0000 - Bfff'ffff area into a
prefetchable and a non-prefectable one, so i will be urged to programm
PMM2 as well.
