Ok, I adapted the E7501 code, I think this will work great. I will test
tonight, and get back.
dimm_start = 0;
for (i = 0; i < DIMM_SOCKETS; ++i) {
if (i == 0) {
dimm_end = pci_read_config8(ctrl->d0, DRB + 1);
} else if (i == 1) {
dimm_end = pci_read_config8(ctrl->d0, DRB + 3);
}
if (dimm_end > dimm_start) {
/* Convert to a 32 bit address. NOTE: 2^25 == 32 MB */
dimm_start_address = dimm_start << 25;
RAM_DEBUG_MESSAGE(" Sending RAM command to 0x");
RAM_DEBUG_HEX32(dimm_start_address + addr_offset);
RAM_DEBUG_MESSAGE("\r\n");
read32(dimm_start_address + addr_offset);
/* Set the start of the next DIMM. */
dimm_start = dimm_end;
}
}
