In order to move Tegra's debug-macro.S to a common location for single zImage, it must not rely on any machine-specific header files such as <mach/iomap.h>. Duplicate the few physical address definitions that debug-macro.S relies upon directly into the file. To avoid tegra_io_desc[] requiring shared knowledge of the UART mapping's virtual address, use a virtual address outside the ranges in tegra_io_desc[]. Call debug_ll_io_init() to propagate the mapping beyond the early pages tables. Signed-off-by: Stephen Warren <swarren@nvidia.com>
