Instead, derive -march and -mcpu from the target MCU in
target-config.mk. Also (on STM32F4) add the necessary floating point
flags. The CodeSourcery toolchains don't support these, so we'll need
to prepare alternative toolchains when F4 support is official.

Works with officially supported CodeSourcery toolchain. May need
tweaks for users with a more modern arm-none-eabi-g++.

Merge the long-lived (too long; future changes like these will need to
proceed more incrementally) development branch of libmaple, containing
experimental STM32F2 and STM32F1 value line support, into master.
This required many changes to the structure of the library. The most
important structural reorganizations occurred in:
- 954f9e5: moves public headers to include directories
- 3efa313: uses "series" instead of "family"
- c0d60e3: adds board files to the build system, to make it easier to
add new boards
- 096d86c: adds build logic for targeting different STM32 series
(e.g. STM32F1, STM32F2)
This last commit in particular (096d86c) is the basis for the
repartitioning of libmaple into portable sections, which work on all
supported MCUs, and nonportable sections, which are segregated into
separate directories and contain all series-specific code. Moving
existing STM32F1-only code into libmaple/stm32f1 and wirish/stm32f1,
along with adding equivalents under .../stm32f2 directories, was the
principal project of this branch.
Important API changes occur in several places. Existing code is still
expected to work on STM32F1 targets, but there have been many
deprecations. A detailed changelog explaining the situation needs to
be prepared.
F2 and F1 value line support is not complete; the merge is proceeding
prematurely in this respect. We've been getting more libmaple patches
from the community lately, and I'm worried that the merge conflicts
with the old tree structure will become painful to manage.
Conflicts:
Makefile
Resolved Makefile conflicts manually; this required propagating
-Xlinker usage into support/make/target-config.mk.

Having separate linker scripts for all the boards is a bad idea. Most
boards really only need to specify MEMORY and the appropriate
REGION_ALIASES() so that support/ld/common.inc can do its work. Not
having infrastructure for this leads to duplication -- viz. the Maple
Mini linker scripts are identical to the Maple's, and the
olimex_stm32_h103 linker directory is just a symlink to
Maple's. Clearly, the current structure is wrong.
To fix it, instead of having per-board subdirectories of support/ld/,
add per-MEMORY subdirectories of (new) support/ld/stm32/mem/. The
per-board .mk files under support/mk/board-includes/ now reference
these directly, and target-config.mk and the Makefile handle this
appropriately. We move some other stuff around in target-config.mk to
make this all more convenient, and even allow more overriding of the
libmaple defaults on a per-board basis. Custom board hacks will be
easier now.
Unfortunately, lots of duplication under support/ld/stm32/mem/ is
necessary, as the LENGTH attribute in a MEMORY region specification
doesn't support arithmetic expressions, and ld doesn't seem to have
any way to specify MEMORY at the command line (why?!). If we find a
better way than this, we should do it.
If a board (e.g. Maple Native) _does_ really need special
memory-related configuration, you can always put a per-board
subdirectory of support/ld/stm32/mem. We do this here to configure the
heap.

As the number of boards increases, it's less practical to keep a list
of them in the help target output (notice also that some have been
forgotten). This target can't get out of date unless we change how the
board-includes/ directory works.

The good news is that <libmaple/usb.h> and <libmaple/usb_cdcacm.h> did
turn out generic enough in what they specify to go on unchanged.
However, we can't just go on assuming that there's USB just because
we're on an F1. Now that there's value line in the tree, we need to be
more careful (value line F1s don't have USB peripherals). To that end,
make all the F1 board-includes/*.mk files specify what line their MCU
is with an MCU_F1_LINE variable. Use that to hack
libmaple/usb/rules.mk so we only try to build the USB module under
appropriate circumstances.
While we're at it, add a vector_symbols.inc for value line MCUs under
support/ld/. We need this to get the target-config.mk modifications
implied by the addition of MCU_F1_LINE. We'll fix up some other
performance-line-isms under libmaple/stm32f1 in a separate commit.
Also in libmaple/usb/:
- Move everything into a new stm32f1 directory. Due to aforementioned
rules.mk hacks, there is no immediate need for an stm32f2
directory (USB support doesn't exist there).
- Update the README for style and content.

Add STM32_HAVE_USB feature test macro requirement for
<series/stm32.h>. This will let us test if we've got a USB peripheral.
wirish/stm32f1/boards_setup.cpp is set up to use this when turning on
USB CDC ACM support at init() time.
Rework the STM32F1 <series/stm32.h> to make it easier to support the
various lines that subdivide that series. We don't really support
anything besides performance line yet, but there's been enough
enthusiasm for value and connectivity line support in the past that
these hooks seem worth adding. This means adding an STM32_F1_LINE
macro and STM32_F1_LINE_[PERFORMANCE,VALUE,ACCESS,CONNECTIVITY] macros
for values that STM32_F1_LINE can take, and generalizing the rest of
the file to begin taking this into account. Some TODOs remain, but
filling these in is the responsibility of future libmaple porting
efforts.
One pleasant consequence of the F1 stm32.h rework is that the build
system no longer has to tell us what density of F103 we're building
for, so remove that from the relevant support/make/board-includes/
files.
Add some tweaks to <libmaple/stm32.h> and the STM32F2 stm32.h header
to make sure this went through properly, and continues to go through
properly in the future.

Add an MCU_SERIES variable to each of the files under
support/make/board-includes, which declares the series as "stm32f1" in
each case.
Use this in target-config.mk when determining LD_SERIES_PATH (with a
hack since we only support performance line) and
LIBMAPLE_MODULE_SERIES. We must move support/ld/stm32/series/f1 to
.../series/stm32f1 as a side-effect.
Adding support for other series (e.g. "stm32f2") should now be a
matter of filling in the contents of libmaple/<series>/ and
support/ld/stm32/<series>/ appropriately (along with moving the rest
of the nonportable code out of the libmaple core and into the STM32F1
series submodule).

target-config.mk is getting a little long with all the boards in
it. Break out the board-specific bits into individual files under
support/make/board-includes.
This has the added benefit that adding a new board requires less
dirtying of the working tree, which is nice for jumping around
branches with an experimental board.

This is for greater consistency with the ST application notes, which
refer to migrating "across" series (e.g. F1 to F2), but compatibility
"within" a family (e.g. F1).
So:
- Move libmaple/stm32x/include/family to .../include/series/ and fix
up includes appropriately.
- Refer to "family" headers as "series" headers in comments.
- Make similar "find and replace"-style changes to build system
variable names and comments.
- Move support/ld/stm32/family to .../stm32/series.

Move into target-config.mk. Build it up bit-by-bit as the build goes
on. Repeat the DENSITY defines once per board in target-config.mk,
since they don't make sense on STM32F2.

Move
support/ld/stm32/f1/performance/vector_symbols.inc
to
support/ld/stm32/family/f1/performance/vector_symbols.inc
Creating directory "family" under support/ld/stm32 will allow parallel
directories (e.g. support/ld/stm32/mcu) to exist, which allows an
eventual linker script cleanup to go much more smoothly.

It's very annoying to have to build libmaple projects in-tree. Users
are just copying the repository everywhere. That's stupid. So I made this:
https://github.com/mbolivar/example-libmaple-project
It needs these patches to work.
Add a header and footer for rules.mk files, so we can change them
around and things will continue to work for the users, who just
include them.
In Makefile, add USER_MODULES to LIBMAPLE_MODULES if it's
nonempty. This is the hook you use to get your code compiled and
linked correctly.
Hack build-targets.mk for stupid reasons I hope to fix later. For now,
you'll need an empty main.cpp in BOTH the libmaple directory and your
directory if you want things to work the way you'd expect.

Remove libcs3-related bits from support/ld. Break them out into
libmaple proper and Wirish as appropriate: vector table definition and
ISR declarations go into libmaple proper, and startup code goes into
Wirish. Vector table symbols are included into common.inc from an
STM32 family-specific directory under support/ld/stm32.
This is a combination of 5 commits. Individual commit messages follow:
libcs3_stm32_src: Don't depend on cs3.h.
So we can use the existing toolchain.
Move ISR decls/vector table into libmaple proper.
This allows us to configure the vector table on a per-family basis.
- Move
support/ld/libcs3_stm32_src/stm32_isrs.S
stm32_vector_table.S
to
libmaple/stm32f1/isrs_performance.S
vector_table_performance.S,
respectively.
The directory libmaple/stm32f1/ is intended to hold all
STM32F1-specific code within libmaple. Obviously, there's a lot of
work to do before this becomes true.
- support/ld/libcs3_stm32_src/Makefile: Don't try to compile
stm32_isrs.S and stm32_vector_table.S anymore.
- Add libmaple/stm32f1/rules.mk to include these new files in the
standard libmaple build.
- support/make/target-config.mk: Add LIBMAPLE_MODULE_FAMILY, which
selects a directory to use as a family-specific libmaple
submodule.
- Makefile: Add LIBMAPLE_MODULE_FAMILY to LIBMAPLE_MODULES.
Remove support/ld/libcs3_stm32_src and derived object files.
From support/ld/libcs3_stm32_src, move start.S and start_c.c into
Wirish. Modify wirish/rules.mk accordingly.
Delete support/ld/libcs3_stm32_*_density.a. These are no longer
necessary, as the relevant objects are included in the standard Wirish
build. Remove the GROUP statements from the board linker scripts
accordingly.
Remove SEARCH_DIR(.) from common.inc; it's no longer necessary. Also
fix up some comments that are now out of date.
wirish/start_c.c: Don't use CS3-style memory initialization.
Switch memory initialization to a simpler style of initializing .data
if necessary, then zeroing .bss. Initializing .data is only necessary
during Flash builds, since during RAM builds, LOADADDR(.data) ==
ADDR(.data).
This makes libmaple completely incompatible with the CS3 startup
sequence. Subsequent commits will clean up the namespace to reflect
that fact.

- support/make/target-config.mk: add LD_FAMILY_PATH, the directory to
search for STM32 family-specific link configuration files. For now,
this is just a stub which points to support/ld/stm32/f1/performance,
since that's all we currently support. We can add the logic to
support different STM32 families here later.
- Makefile: Pass -L $(LD_FAMILY_PATH) to linker.
- Rename support/ld/names.inc to
support/ld/stm32/f1/performance/vector_symbols.inc.
- common.inc: INCLUDE vector_symbols.inc instead of names.inc.

Redirect thread-mode execution to a fail routine which throbs the LED to
indicate a hard fault. Because the fail routine runs in thread mode
with interrupts on, USB auto-reset should now work. Test by executing

that the auto-reset continues to work.

target was, regardless of the environment's value of MAPLE_TARGET.

Major build system rewrite. New and exciting:
1. Proper dependency tracking. All source files including header files
should be properly tracked and recompiled as necessary when they are
changed.
2. Build-type tracking. If the target changes from 'ram' to 'flash,'
for example, the build system will force a rebuild rather than
incorrectly link modules to a different address.
3. New targets:
The old 'ram,' 'flash,' and 'jtag' targets have been replaced with
the environment variable MAPLE_TARGET, which controls the link address.
Users can either export it to their environment, or pass MAPLE_TARGET on
the command-line. Once this is set, sketches can be compiled with 'make
sketch,' or simply 'make.'
Note: the default is MAPLE_TARGET='flash.'
The target 'install' now automagically uploads the sketch to the board
using the appropriate method.
The 'run' target has been renamed to 'debug.' It starts an openocd gdb
server.
4. Odds and ends:
-Verbose and 'quiet' modes. Set V=1 for verbose compilation, the default
is quiet.
-Object file sizes and disassembly information is generated and placed
in build/$(BOARD).sizes and build/$(BOARD).disas, respectively.
-Parallel make with -j should speed things up if you have multiple
cores.
