[AVR32] Add support for AT32AP7001 and AT32AP7002

2008-01-25T07:31:41+00:00

These are derivatives of the AT32AP7000 chip, which means that most of
the code stays the same. Rename a few files, functions, definitions
and config symbols to reflect that they apply to all AP700x chips, and
exclude some platform devices from chips where they aren't present.

[AVR32] Make I/O access macros work with external devices

2007-04-27T11:44:14+00:00

Fix the I/O access macros so that they work with externally connected
devices accessed in little-endian mode over any bus width:

* Use a set of macros to define I/O port- and memory operations
  borrowed from MIPS.
* Allow subarchitecture to specify address- and data-mangling
* Implement at32ap-specific port mangling (with build-time
  configurable bus width. Only one bus width at a time supported
  for now.)
* Rewrite iowriteN and friends to use write[bwl] and friends
  (not the __raw counterparts.)

This has been tested using pata_pcmcia to access a CompactFlash card
connected to the EBI (16-bit bus width.)

[AVR32] Add mach-specific Kconfig

2007-04-27T11:43:27+00:00

Include at32ap-specific Kconfig file from top-level Kconfig file. The
at32ap Kconfig is currently empty, but it will grow some machine-
specific options soon.
