Paul Sokolovsky	354d17523f	modmachine: Implement physical memory access using /dev/mem (Linux, etc). This requires root access. And on recent Linux kernels, with CONFIG_STRICT_DEVMEM option enabled, only address ranges listed in /proc/iomem can be accessed. The above compiled-time option can be however overriden with boot-time option "iomem=relaxed". This also removed separate read/write paths - there unlikely would be a case when they're different.	2015-07-08 11:37:23 +03:00
Paul Sokolovsky	0116218fa8	modmachine: Add new module to access hardware, starting with physical memory. Refactored from "stm" module, provides mem8, mem16, mem32 objects with array subscript syntax.	2015-05-04 13:05:12 +03:00

modmachine: Implement physical memory access using /dev/mem (Linux, etc).

This requires root access. And on recent Linux kernels, with
CONFIG_STRICT_DEVMEM option enabled, only address ranges listed in
/proc/iomem can be accessed. The above compiled-time option can be
however overriden with boot-time option "iomem=relaxed".

This also removed separate read/write paths - there unlikely would
be a case when they're different.
