ARM: 7672/1: uncompress debug support for multiplatform build
Instead of giving zero support of uncompress debug for multiplatform build, the patch turns uncompress debug into one part of DEBUG_LL support. When DEBUG_LL is turned on for a particular platform, uncompress debug works too for that platform. OMAP and Tegra are exceptions here. OMAP low-level debug code places data in the .data section, and that is not allowed in decompressor. And Tegra code has reference to variable that's unavailable in decompressor but only in kernel. That's why Kconfig symbol DEBUG_UNCOMPRESS controlling multiplatform uncompress debug support is defined with !DEBUG_OMAP2PLUS_UART && !DEBUG_TEGRA_UART. It creates arch/arm/boot/compressed/debug.S with CONFIG_DEBUG_LL_INCLUDE included there, implements a generic putc() using those macros, which will be built when DEBUG_UNCOMPRESS is defined.
