MIPS: CPS: Early debug using an ns16550-compatible UART

2015-11-11T07:34:25Z

Provide support for outputting early debug information, in the form of various register values should an exception occur, during the early bringup of secondary cores. This code requires an ns16550-compatible UART accessible from the secondary core, and is written in assembly due to the environment in which such early exceptions occur where way may not have a stack, be coherent or even have initialised caches.

Pull MIPS updates from Ralf Baechle: "This is the main pull request for 4.3 for MIPS. Here's the summary: Three fixes that didn't make 4.2-stable: - a -Os build might compile the kernel using the MIPS16 instruction set but the R2 optimized inline functions in are implemented using 32-bit wide instructions which is invalid. - a build error in pgtable-bits.h for a particular kernel configuration. - accessing registers of the CM GCR might have been compiled to use 64 bit accesses but these registers are onl 32 bit wide. And also a few new bits: - move the ATH79 GPIO driver to drivers/gpio - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h, change ATH79 accordingly. - fix definition of pgprot_writecombine - add an implementation of dma_map_ops.mmap - fix alignment of quiet build output for vmlinuz link - BCM47xx: Use kmemdup rather than duplicating its implementation - Netlogic: Fix 0x0x prefixes of constants. - merge Bjorn Helgaas' series to remove most of the weak keywords from function declarations. - CP0 and CP1 registers are best considered treated as unsigned values to avoid large values from becoming negative values. - improve support for the MIPS GIC timer. - enable common clock framework for Malta and SEAD3. - a number of improvments and fixes to dump_tlb(). - document the MIPS TLB dump functionality in Magic SysRq. - Cavium Octeon CN68XX improvments. - NetLogic improvments. - irq: Use access helper irq_data_get_affinity_mask. - handle MSA unaligned accesses. - a number of R6-related math-emu fixes. - support for I6400. - improvments to MSA support. - add uprobes support. - move from deprecated __initcall to arch_initcall. - remove finish_arch_switch(). - IRQ cleanups by Thomas Gleixner. - migrate to new 'set-state' interface. - random small cleanups" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (148 commits) MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.
