Hi Simon,

Another workaround is to use a mulit-image file with three images
(kernel, initrd, blob) and ignore the second one by calling "bootm
<addr> -". Note that the second image in the file can a bogus one-byte
file (it needs to be at least one byte in size, because mkimage refuses
the create a multi-image file with a zero-sized member).

Note that this booting scenario will be supported in a much more elegant
manner once the new image format is developed. Please stay tuned.
