I don't know if there are any ideas how to handle it, but using a cpp symbol won't work I guess. So I think it's not worth to touch arch_decomp_setup without solving the multi-SoC case.

Ignore this - it's needed for calls to arch_decomp_setup().

Nice patch series! I like this approach, because it allows us to: 1. Use this DT entry entry for earlyprintk, and then CONFIG_DEBUG_LL can be separated from all this 2. CONFIG_DEBUG_LL can now be reserved for the low-level debugging when bringing up new SoC/board etc 3. This allows seeing uncompress errors on unsupported boards, which is important when working on multiarch support 4. With this series we can turn earlyprintk into something that can be compiled into production kernels too I have not looked through the patch series if it uses still CONFIG_DEBUG_LL somewhere, but if it does, it should be separated from that. Cheers, Tony

arch_decomp_wdog is only used by lib/inflate.c which isn't used by the ARM arch since 2.6.33. Stop carrying it around and re-adding it with every new machine. The only real user was the Samsung platform, but since this feature wasn't working for over a year, it's probably not needed at all.
