* IO port access primitives |
||||
* ------------------------- |
||||
* |
||||
* The NDS32 doesn't have special IO access instructions just like ARM; |
||||
* all IO is memory mapped. |
||||
* Note that these are defined to perform little endian accesses |
||||
* only. Their primary purpose is to access PCI and ISA peripherals. |
||||
* |
||||
* Note that for a big endian machine, this implies that the following |
||||
* big endian mode connectivity is in place, as described by numerious |
||||
* ARM documents: |
||||
* |
||||
* PCI: D0-D7 D8-D15 D16-D23 D24-D31 |
||||
* ARM: D24-D31 D16-D23 D8-D15 D0-D7 |
||||
* |
||||
* The machine specific io.h include defines __io to translate an "IO" |
||||
* address to a memory address. |
||||
* |
||||
* Note that we prevent GCC re-ordering or caching values in expressions |
||||
* by introducing sequence points into the in*() definitions. Note that |
||||
* __raw_* do not guarantee this behaviour. |
||||
* |
||||
* The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space. |
