[PATCH v2] ARM: exynos: add debug_ll_io_init() call in exynos_init_io()

2013-06-05 Thread Doug Anderson
If the early MMU mapping of the UART happens to get booted out of the TLB between the start of paging_init() and when we finally re-add the UART at the very end of s3c_init_cpu(), we'll get a hang at bootup if we've got early_printk enabled. Avoid this hang by calling debug_ll_io_init() early. Wi
