If host and target endianness does not match, loding an initrd does not
work, but results in a kernel log message similar to the following.
... MOUNT_ROOT_RDONLY - 00000000
... RAMDISK_FLAGS - 00000000
... ORIG_ROOT_DEV - 00000000
... LOADER_TYPE - 01000000
... INITRD_START - 00008001
... INITRD_SIZE - 00a01b00
Booting machvec: RTS7751R2D
initrd must be page aligned
initrd disabled
Fix by writing boot parameters with appropriate endianness conversion.
