Hi All,
I'm trying to bring-up a PCIe based NIC(e1000e) card on a PowerPC-440 based
board, I'm able to list this device under lspci from the user space, but the
driver probe fails and looks like mmio mapping doesn't look right. Following is
the bootlog of the kernel. Can anyone point out what is going wrong here? The
kernel is a relocatable one and system memory is mapped at 0x5000_0000 to
0x6000_0000
I dont have a serial console, I use ttyprintk to get the userspace prints (on
dmesg).
