Subject: [PATCH 4/4] ppc4xx: load Bamboo kernel, initrd, and
fdt at fixed addresses
We can't use the return value of load_uimage() for the kernel
because it
can't account for BSS size, and the PowerPC kernel does not relocate
blobs before zeroing BSS.
Instead, we now load at the fixed addresses chosen by u-boot
(the normal
firmware for the board).
What will us do if the uImage become bigger and fixed size is not
enough?
That was my question to Edgar, which was not answered. In u-boot, one
would change some environment variables. With this code in qemu, the
only recourse would be to edit ppc440_bamboo.c and rebuild.
Perhaps in the future we can do something more sophisticated by
specifying load addresses in a qemu device tree, but I don't
understand that stuff enough to know if that is an intended use.
