In https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=870185#35 I
concluded it wasn't, perhaps I'm wrong though.
Can someone confirm whether the issue is that the u-boot load addresses
for kernel and initrd are conflicting or if it is the kernel's
target/decompression address and u-boot's initrd address which are
conflicting? The symptoms seem to suggest the kernel is being
decompressed over the initrd.
Since we don't want to change the u-boot we can't easily influence the
initrd address (since it doesn't use a u-boot header on this platform).
So it would seem the only possibility (other than shrinking the kernel)
would be to change the address at which it decompresses itself so it
doesn't conflict with the initrd.
Not sure how hard that would be -- it might be as simple as tweaking a
constant in the source or a Kconfig option, but I suspect it might
involve changing early boot assembly...
Ian.
