    ARM: 7672/1: uncompress debug support for multiplatform build · 3b4af9bc
    Shawn Guo authored
    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.
