    riscv: K210: Add a built-in device tree · 8bb66174
    Palmer Dabbelt authored
    The K210's bootloader does not provide a device tree. Give the ability
    to providea builtin one with the SOC_KENDRYTE_K210_BUILTIN_DTB option.
    If selected, this option result in the definition of a builtin DTB
    entry in the k210 sysctl driver.
    
    If defined, the builtin DTB entry points to the default k210.dts device
    tree file and is keyed with the vendor ID 0x4B5, the arch ID
    0xE59889E6A5A04149 ("Canaan AI" in UTF-8 coded Chinese) and the impl ID
    0x4D41495832303030 ("MAIX200"). These values are reported by the SiPEED
    MAIXDUINO board, the SiPEED MAIX Go board and the SiPEED Dan Dock board.
    
    [Thanks to Damien for the K210 IDs]
