Re: [coreboot] ram init help on the i82830

[Joseph Smith]

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;
    	}
    }
