[PATCH 0/6] MIPS: rework ns16550 debug_ll

[Antony Pavlov]

This patch series adds low-level debug ns16550 output helpers
for MIPS pbl. This helpers make possible easely produce
debug output via ns16550-like UART on very early pbl stage.

[PATCH 1/6] MIPS: XBurst: use mach-specific debug_ll setup
[PATCH 2/6] MIPS: pbl: add low-level debug asm macros for ns16550
[PATCH 3/6] MIPS: rzx50: pbl: use debug_ll
[PATCH 4/6] MIPS: rzx50_defconfig: use UART1 for low-level debug
[PATCH 5/6] MIPS: malta: adapt for new debug_ll
[PATCH 6/6] MIPS: unificate ns16550 debug_ll support code
