ARM: OMAP2+: Remove now obsolete uncompress.h and debug-macro.S
These are no longer needed, we now have to select the debug_ll port manually. The new multiplatform version of the debug_ll code is in arch/arm/include/debug/omap2plus.S. Signed-off-by: Tony Lindgren <tony@atomide.com>hifive-unleashed-5.1
