booting single uImage on platforms with different base addresses for SDRAM

[Peter De Schrijver]

Hi,

Currently uImages have the load address hardcoded. As we now try to support
as many ARM platforms as possible with a single binary, this becomes a
problem. On tegra20 SDRAM starts at physical address 0, but on tegra30 SDRAM
starts at 0x80000000. It's possible to build a kernel image which can deal
with this, but the uImage still uses a hardcoded address. This results
in requiring 2 different uImages even though the zImage is the same.

Has anyone thought of a solution to this problem?

Thanks,

Peter.
