|

*
|

* 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.
