2016-02-01MIPS: Support dynamic I/O port base addressPaul Burton
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 <paul.burton@imgtec.com>
2016-02-01MIPS: Remove SLOW_DOWN_IOPaul Burton
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 <paul.burton@imgtec.com>
2016-01-25mips: asm/io.h: Add in <linux/bug.h>Tom Rini
As part of the bug.h / BUILD_BUG_* clean up, this file was missed. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-01-16MIPS: implement bit manipulating I/O accessorsDaniel Schwierzeck
Add support for functions clrbits_X(), setbits_X() and clrsetbits_X() on MIPS. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2016-01-16MIPS: sync I/O related header files with linux-4.4Daniel Schwierzeck
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 <daniel.schwierzeck@gmail.com>
2015-07-02MIPS: change 'extern inline' to 'static inline'Daniel Schwierzeck
The kernel changed it a long time ago. Also this is now broken on gcc-5.x. Reported-by: Andy Kennedy <andy.kennedy@adtran.com> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2013-11-08include: delete include/linux/config.hMasahiro Yamada
Linux Kernel abolished include/linux/config.h long time ago. (around version v2.6.18..v2.6.19) We don't need to provide Linux copatibility any more. This commit deletes include/linux/config.h and fixes source files not to include this. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2013-06-08MIPS: fix __raw_* IO accessorsGabor Juhos
The purpose of the __raw* IO accessors is to provide IO access in native-endian order. However in the current MIPS implementation, the 16 and 32 bit variants of the __raw accessors are swapping the values on big-endian systems if the CONFIG_SWAP_IO_SPACE option is enabled. The patch changes the IO accessor macros to fix this broken behaviour. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
2013-01-22MIPS: convert IO port accessor functions to 'static inline'Gabor Juhos
The currently used 'extern inline' directive causes the following compiler warnings if CONFIG_SWAP_IO_SPACE is defined: <...>/include/asm/io.h:345:1: warning: '__fswab32' is static but used in inline function '__outlc_p' which is not static [enabled by default] <...>/include/asm/io.h:345:1: warning: '__fswab32' is static but used in inline function '__outl_p' which is not static [enabled by default] <...>/include/asm/io.h:345:1: warning: '__fswab32' is static but used in inline function '__outlc' which is not static [enabled by default] <...>/include/asm/io.h:345:1: warning: '__fswab32' is static but used in inline function '__outl' which is not static [enabled by default] <...>/include/asm/io.h:344:1: warning: '__fswab16' is static but used in inline function '__outwc_p' which is not static [enabled by default] <...>/include/asm/io.h:344:1: warning: '__fswab16' is static but used in inline function '__outw_p' which is not static [enabled by default] <...>/include/asm/io.h:344:1: warning: '__fswab16' is static but used in inline function '__outwc' which is not static [enabled by default] <...>/include/asm/io.h:344:1: warning: '__fswab16' is static but used in inline function '__outw' which is not static [enabled by default] <...>/include/asm/io.h:341:1: warning: '__fswab32' is static but used in inline function '__inlc_p' which is not static [enabled by default] <...>/include/asm/io.h:341:1: warning: '__fswab32' is static but used in inline function '__inl_p' which is not static [enabled by default] <...>/include/asm/io.h:341:1: warning: '__fswab32' is static but used in inline function '__inlc' which is not static [enabled by default] <...>/include/asm/io.h:341:1: warning: '__fswab32' is static but used in inline function '__inl' which is not static [enabled by default] <...>/include/asm/io.h:340:1: warning: '__fswab16' is static but used in inline function '__inwc_p' which is not static [enabled by default] <...>/include/asm/io.h:340:1: warning: '__fswab16' is static but used in inline function '__inw_p' which is not static [enabled by default] <...>/include/asm/io.h:340:1: warning: '__fswab16' is static but used in inline function '__inwc' which is not static [enabled by default] <...>/include/asm/io.h:340:1: warning: '__fswab16' is static but used in inline function '__inw' which is not static [enabled by default] Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
2013-01-22MIPS: use inline directive for __in*s functionsGabor Juhos
All other IO accessor functions are using the 'inline' directive. Use that also for the __in*s to make it consistent with the other variants. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>

2010-04-13Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser
This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
