openrisc: Add support for external initrd images
In OpenRISC we set the initrd_start and initrd_end based on the symbols
we setup in vmlinux.lds.S. However, this is not needed if we use the
generic linker description in INIT_DATA_SECTION.
Removing our own initrd setup reduces code, but also the generic code
supports loading external initrd images. A bootloader can load a rootfs
image into memory and we can configure devicetree to load it with:
chosen {
bootargs = "earlycon";
stdout-path = "uart0:115200";
linux,initrd-start = < 0x08000100 >;
linux,initrd-end = < 0x08200000 >;
};
