Damien George 278f3592d4 extmod/modmachine: Use uintptr_t instead of mp_uint_t for address type. 2015-11-29 14:25:04 +00:00
Paul Sokolovsky 2a6660ba59 extmod/modmachine: Avoid conflicts with system PAGE_SIZE define, if any. 2015-08-18 00:31:31 +03:00
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.

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.
