Hi all,
Does anyone knows how to set the DDR data bus width to 16Bit in linux?
I've found that
option in U-Boot in the MPC8313ERDB_config file. (verfied with a memory
dump of the
CPU register (DDR_SDRAM_CFG) - the 16Bit DBW is set(10b) ). But after
starting
linux the value is set to 00b
you have to do it via your bootloader (u-boot) which sets up
the DDR memory controller.
Linux (already) assumes memory is available.
Are you sure linux kernel is changing DDR_SDRAM_CFG ?
When our linux-2.6.28 kernel is up, it's still 0xc308 when I read
physical address 0xe0002110.
Btw. We

Hi Frank,
Yes, it's 0xC310 for 16 bit. I showed the 32bit value.
Yes, to go to 16 bit bus-width (1 DDR(2) device), this is the only
change needed in u-boot, assuming you have 2 DDR(2) devices (like 8313E-RDB)
which together provide 16+16 = 32bit bus-width.
Since, surprisingly, the 16 bit

The following series allows the generic NVRAM driver to access MMIO based
NVRAMs. In addition it enables support for NVRAMs of sizes differing from those
found on PowerPC Macs (providing a safe fallback). Patches are also included to
enable support for the NVRAM found on the GE Fanuc PPC9A,
Add a byte length read and write interface compatible with the nvram_generic

Yes. If you enable jumbo frames, the results will be definitely better. My
result is with jumbo frame of 8982 enabled.
If you say your CPU is 600 MHz, I guess there is still potential for you to
improve the speed. In our case we had only 300 MHz and got a similar value of
