* MIPS: Use CPHYSADDR to implement mips32 virt_to_physPaul Burton2016-05-311-4/+1
| | | | | | | | | | | | | | | | | | Use CPHYSADDR to implement the virt_to_phys function for converting from a virtual to a physical address for MIPS32, much as is already done for MIPS64. This allows for virt_to_phys to work regardless of whether the address being translated is in kseg0 or kseg1, unlike the previous subtraction based approach which only worked for addresses in kseg0. This allows for drivers to provide an address to virt_to_phys without needing to manually ensure that kseg1 addresses are converted to equivalent kseg0 addresses first. This patch is equivalent to this Linux patch currently waiting to be reviewed & merged: https://patchwork.linux-mips.org/patch/12564/ Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* MIPS: Support dynamic I/O port base addressPaul Burton2016-02-011-21/+27
| | | | | | | | | | | | 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>
* MIPS: Remove SLOW_DOWN_IOPaul Burton2016-02-011-37/+3
| | | | | | | | | 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>

* MIPS: sync I/O related header files with linux-4.4Daniel Schwierzeck2016-01-161-362/+399
| | | | | | | | | | | | | 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>
* MIPS: change 'extern inline' to 'static inline'Daniel Schwierzeck2015-07-021-6/+6
| | | | | | | | 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>
* include: delete include/linux/config.hMasahiro Yamada2013-11-081-1/+0
| | | | | | | | | | | | 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>
* MIPS: fix __raw_* IO accessorsGabor Juhos2013-06-081-13/+13
| | | | | | | | | | | | | | 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>

* Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser2010-04-131-0/+492
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>
