(It prints Uncompressing... done. but I guess that's > done with the physical address.) Hmm maybe we now need to get rid of the machine based detection code for DEBUGLL like we did for mach-omap2. Just get rid of arch_decomp_setup() in mach-omap1 uncompress.h file and make sure the assembly code only relies on the the Kconfig options only. That needs to be done at least for device tree based support since we use a generic machine ID. But maybe with multiarch support we need to rely on generic uncompress.h and assembly.
