19 * Stolen area that contains debug uart physical and virtual addresses. These
20 * addresses are filled in by the uncompress.h code, and are used by the debug
21 * macros in debug-macro.S.
23 * This area sits just below the page tables (see arch/arm/kernel/head.S).
24 * We define it as a relative offset from start of usable RAM.
