MIPS: Support dynamic I/O port base address

2016-02-01T21:13:25Z

The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a non-zero I/O port base, so select this option only for Malta. Signed-off-by: Paul Burton

MIPS: Remove SLOW_DOWN_IO

2016-02-01T21:13:25Z

CONF_SLOWDOWN_IO is never set for any target, so remove the dead code in the SLOW_DOWN_IO macro. This is done in preparation for changes to mips_io_port_base which can be avoided in this path by removing it entirely. Signed-off-by: Paul Burton

MIPS: fix SPDX license identifier in remaining arch header files

2016-01-16T20:06:46Z

Add a SPDX license identifier to MIPS header files where it is still missing. Signed-off-by: Daniel Schwierzeck

MIPS: sync processor and register definitions with linux-4.4

2016-01-16T20:06:46Z

Update definitions for processor, registers as well as assemby macros. Signed-off-by: Daniel Schwierzeck

MIPS: sync I/O related header files with linux-4.4

2016-01-16T20:06:46Z

Mainly sync asm/io.h to get a working ioremap() implementation as well as the full set of I/O accessors. Pull in additional header files to make this work. Furthermore port over the directory 'arch/mips/include/asm/mach-generic/' with contains default definitions for I/O and memory spaces and default implementations for mapping those spaces. All files in that directory can be overwritten by a SoC/machine. Signed-off-by: Daniel Schwierzeck

MIPS: kconfig: add option for MIPS_L1_CACHE_SHIFT

2016-01-16T20:06:46Z

Add Kconfig symbol for L1 cache shift like the kernel does. The value of CONFIG_SYS_CACHELINE_SIZE is not a reliable source for ARCH_DMA_MINALIGN anymore, because it is optional on MIPS. If CONFIG_SYS_CACHELINE_SIZE is not defined by a board, the cache sizes are automatically detected and ARCH_DMA_MINALIGN would be set to 128 Bytes. The default value for CONFIG_MIPS_L1_CACHE_SHIFT is 5 which corresponds to 32 Bytes. All current MIPS boards already used that value. While on it, fix the Malta board to use a value of 6 like the kernel port does. Signed-off-by: Daniel Schwierzeck

MIPS: create .text sub-sections for assembler functions

2016-01-16T20:06:45Z

Put all functions coded in assembly in sub-sections of section .text. This allows the linker to garbage collect unused assembly functions too. Signed-off-by: Daniel Schwierzeck
