    dtoc: Add support for 32 or 64-bit addresses · c20ee0ed
    Simon Glass authored
    When using 32-bit addresses dtoc works correctly. For 64-bit addresses it
    does not since it ignores the #address-cells and #size-cells properties.
    Update the tool to use fdt64_t as the element type for reg properties when
    either the address or size is larger than one cell. Use the correct value
    so that C code can obtain the information from the device tree easily.
    Alos create a new type, fdt_val_t, which is defined to either fdt32_t or
    fdt64_t depending on the word size of the machine. This type corresponds
    to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types
    since they are defined to phys_addr_t and phys_size_t which use
    'unsigned long' in the 32-bit case, rather than 'unsigned int'.
    Add tests for the four combinations of address and size values (32/32,
    64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368
    which now need to use the new fdt_val_t type.
