This is how things with with Linux: > load a FIT and select the correct device tree to pass to Linux. I've just skimmed over the git-logs, but I am confused. Please makes it clearer why this is useful. In your way, how SPL is handled? SPL is much more board-specific than U-Boot proper. So, I assume SPL would remain as a per-board image even after achieving one U-Boot proper for multi-boards. Let's say we want to support Board-A, Board-B, Board-C with one U-Boot proper. The U-Boot proper + FIT (including DTB-A, DTB-B, DTB-C) would be generated by one-shot and by one defconfig. But, we would still have to do make board_a_defconfig && make make board_b_defconfig && make make board_c_defconfig && make to generate SPL for each of the three. Is this correct? Supposing my guess is correct, this series would not contribute to decreasing the number of defconfig files. Please explain which problem you are solving with this series. -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe devicetree-compiler" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
