Move libmaple/*.h to (new) libmaple/include/libmaple/. The new
accepted way to include a libmaple header foo.h is with:
#include <libmaple/foo.h>
This is more polite in terms of the include namespace. It also allows
us to e.g. implement the Arduino SPI library at all (which has header
SPI.h; providing it was previously impossible on case-insensitive
filesystems due to libmaple's spi.h).
Similarly for Wirish.
The old include style (#include "header.h") is now deprecated.
libmaple/*.h:
- Change include guard #defines from _FOO_H_ to _LIBMAPLE_FOO_H_.
- Add license headers where they're missing
- Add conditional extern "C" { ... } blocks where they're missing
(they aren't always necessary, but we might was well do it against
the future, while we're at it.).
- Change includes from #include "foo.h" to #include <libmaple/foo.h>.
- Move includes after extern "C".
- Remove extra trailing newlines
Note that this doesn't include the headers under libmaple/usb/ or
libmaple/usb/usb_lib. These will get fixed later.
libmaple/*.c:
- Change includes from #include "foo.h" to #include <libmaple/foo.h>.
Makefile:
- Add I$(LIBMAPLE_PATH)/include/libmaple to GLOBAL_FLAGS. This allows
for users (including Wirish) to migrate their code, but should go
away ASAP, since it slows down compilation.
Wirish:
- Move wirish/**/*.h to (new) wirish/include/wirish/. This ignores
the USB headers, which, as usual, are getting handled after
everything else.
- Similarly generify wirish/boards/ structure. For each supported
board "foo", move wirish/boards/foo.h and wirish/boards/foo.cpp to
wirish/boards/foo/include/board/board.h and
wirish/boards/foo/board.cpp, respectively. Also remove the #ifdef
hacks around the .cpp files.
- wirish/rules.mk: put wirish/boards/foo/include in the include path
(and add wirish/boards/foo/board.cpp to the list of sources to be
compiled). This allows saying:
#include <board/board.h>
instead of the hack currently in place. We can allow the user to
override this setting later to make adding custom board definitions
easier.
- Disable -Werror in libmaple/rules.mk, as the current USB warnings
don't let the olimex_stm32_h103 board compile. We can re-enable
-Werror once we've moved the board-specific bits out of libmaple
proper.
libraries, examples:
- Update includes accordingly.
- Miscellaneous cosmetic fixups.

Moving SPIn Doxygen comments to point of definition in keeping with

Still a polling driver, but the libmaple proper interface exposes
enough that users enable the various interrupts and define their own
IRQ handlers if they feel like it.
Wirish HardwareSPI interface was largely redone; it's more like the
Arduino implementation now, although there are some differences when I
didn't like their API. The old methods are still there, but are
deprecated and slated for deletion in 0.1.0.
New board-specific values: BOARD_NR_SPI, BOARD_SPIx_NSS_PIN,
BOARD_SPIx_MOSI_PIN, BOARD_SPIx_MISO_PIN, and BOARD_SPIx_SCK_PIN, for
x from 1 to BOARD_NR_SPI.
Documentation was updated appropriately.

Tested on wishield, would like some more testing if anybody has more
things that speak spi

-Read DR after each master send, return the response.
-Added a send function to allow you to pass buffers to the SPI peripheral instead of goin a byte at a time.

Initial commit of a polling-based SPI driver. The driver is limited to
synchronous, blocking sends and a 8-bit data frame format. Tested on
SPI1 and SPI2.
Other peripherals are temporarily disabled, and the rx function
is untested until I find a good peripheral to test everything on.
