Now it's up to somebody else to decide if the price difference between a G20 and G25 is worth the engineering time to upgrade U-Boot and Linux kernel to versions that know about device trees...http://cateee.net/lkddb/web-lkddb/ARM_APPENDED_DTB.htmlInteresting. That would still require modifying U-Boot so that at run-time it detects the SoC type and appends the proper DTB to the kernel image, but it that may be less work than "real" DTB support in U-Boot.
The idea of that feature is: - You take the kernel zImage - You take the appropriate dtb file - You concatenate the dtb file into the zImage - You run mkimage on the resulting combined image to create the special uboot format file for uboot to load - You use it with uboot as you have done in the past with non-DT kernels. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net.
