MIPS: fix mips_cache fallback without __builtin_mips_cache

2016-03-09T10:00:40+00:00

The "R" constraint supplies the address of an variable in a register. Use
"r" instead and adjust asm to supply the content of addr in a register
instead.

MIPS: Support dynamic I/O port base address

2016-02-01T21:13:25+00:00

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.

MIPS: Remove SLOW_DOWN_IO

2016-02-01T21:13:25+00:00

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.
