Yangyu Chen 2672031b20 riscv: dts: Move BUILTIN_DTB_SOURCE to common Kconfig ... The BUILTIN_DTB_SOURCE was only configured for K210 before. Since SOC_BUILTIN_DTB_DECLARE was removed at commit d5805af9fe ("riscv: Fix builtin DTB handling") from patch [1], the kernel cannot choose one of the dtbs from then on and always take the first one dtb to use. Then, another commit 0ddd7eaffa ("riscv: Fix BUILTIN_DTB for sifive and microchip soc") from patch [2] supports BUILTIN_DTB_SOURCE for other SoCs. However, this feature will only work if the Kconfig we use links the dtb we expected in the first place as mentioned in the thread [3]. Thus, a config BUILTIN_DTB_SOURCE is needed for all SoCs to choose one dtb to use. For some considerations, this patch also removes default y if XIP_KERNEL for BUILTIN_DTB, as this requires setting a proper dtb to use on the BUILTIN_DTB_SOURCE, else the kernel with XIP but does not set BUILTIN_DTB_SOURCE or unselect BUILTIN_DTB will not boot. Also, this patch removes the default dtb string for k210 from Kconfig to nommu_k210_defconfig and nommu_k210_sdcard_defconfig to avoid complex Kconfig settings for other SoCs in the future.
