On branch sunxi, the target for A23 is 'Ippo_q8h_config'. Note that this is for the q8h tablet I'm using, but since we don't have SPL support, it's fine to use it for any A23 device, as long as you're using the R_UART pads. If not, you'll need to modify boards.cfg and replace "CONS_INDEX=5" with "UART0_PORT_F" to use uart0 which is muxed with mmc0. U-boot support for A23 is minimal at this time. > No, the only two relevant defconfig in mainline are sunxi and multi_v7 > defconfigs, depending on wether you want to enable only the Allwinner > SoCs, or most of the ARMv7 SoCs supported in Linux. For the Linux Kernel, sunxi_defconfig should work fine, though you will need to tweak or create your own device tree file. >> ... and lichee-dev-a23's config is looking for a relative path for the >> toolchain, i think that's what autoconf means by ".../gcc-linaro/!$#@$-gcc: >> no such file or !@#%" >> >> sun4i and sun5i work or wens's repo...

At the least you will get to know your device. And since not all boards are the same, you will get the details you need to tweak the device tree file.
