这个配置方式是不是编译buildroot 或者ubuntu都可以，我用下面的7和8都编译过，uart1都没有，我反编译了一下dtb文件，也没找到uart1的配置。
1. luckfox_lyra_buildroot_sdmmc_defconfig
2. luckfox_lyra_buildroot_spinand_defconfig
3. luckfox_lyra_plus_buildroot_sdmmc_defconfig
4. luckfox_lyra_plus_buildroot_spinand_defconfig
5. luckfox_lyra_plus_ubuntu_sdmmc_defconfig
6. luckfox_lyra_ubuntu_sdmmc_defconfig
7. luckfox_lyra_ultra-w_buildroot_emmc_defconfig
8. luckfox_lyra_ultra-w_ubuntu_emmc_defconfig
9. luckfox_lyra_ultra_buildroot_emmc_defconfig
10. luckfox_lyra_ultra_ubuntu_emmc_defconfig
