Hi all,
We design a board similar as freescale P1020 reference board.
The two PCIe controllers work fine with the default settings which
allocate 512MB to each PCIe controller.
Then we make some changes in u-boot to allocate 1.5GB to PCIe2 and
512MB to PCIe1 (P1_P2_RDB.h and tlb.c), the changes work fine.
Finally, we want to allocate 2GB to PCIe2 and 512MB to PCIe1, but it
failed.
Does anyone know is it possible to map 2GB memory space to PCIe2
controller in P1020 reference board?
Any clue is appreciated.
