Yes, but does the A80 bootloader supports DT and actually fixes it? If not, then you'll still have to have a memory node, just like on the A31 (and presumably on the A23). Maxime

But last I checked none of our board dts files have separate memory nodes. We only have them in the dtsi, with the largest supported ram size as its value. Also the bootloader (u-boot that is) can pass the memory size via atags I think. At least I'm only getting 512MB RAM on my Optimus, due to u-boot incorrectly assuming I only have as much. But that's another problem. :( Would this be a problem when using Android fastboot from the stock u-boot? Cheers ChenYu

IIRC, fastboot passes ATAGS anyway, so as long as you have the configuration option mentionned above, you should be safe.

The A80 Optimus Board is was launched with the Allwinner A80 SoC. It was jointly developed by Allwinner and Merrii. This board has a UART port, a JTAG connector, USB host ports, a USB 3.0 OTG connector, an HDMI output, a micro SD slot, 8G NAND flash, 4G DRAM, a camera sensor interface, a WiFi/BT combo chip, a headphone jack, IR receiver, and additional GPIO headers. This patch adds only basic support.
