Also reduce heap has it does not fit in SRAM anymore (not with current compiler).
(that's ok since if there is more space available, it will be reclaimed).

The initial baud rates of each interface are now forced in the
board init code.
Any modules using USARTs should have fields added to
their settings object to allow the user to change the
baud rate from the default by using the COM layer APIs.
Developers requiring custom baud rates before the settings
objects are in place should locally edit the cfg structs
to specify the desired baud rates.
This should mark an end to the compile-time selection of HW
configurations.
Minor changes in board initialization for all platforms:
- Most config structs are marked static to prevent badly written
drivers from directly referring to config data.
- Adapt to changes in .irq fields in config data.
- Adapt to changes in USART IRQ handling.
Major changes in board initialization for CC:
- Use HwSettings UAVObj to decide which drivers to attach to
the "main" port and the flexi port, and select the appropriate
device configuration data.
- HwSettings allows choosing between Disabled, Telemetry, SBUS,
Spektrum,GPS, and I2C for each of the two ports.
- Use ManualControlSettings.InputMode to init/configure the
appropriate receiver module, and register its available rx channels
with the PIOS_RCVR layer. Can choose between PWM, Spektrum and PPM
at board init time. PPM driver is broken, and SBUS will work once
it is added to this UAVObj as an option.
- CC build now includes code for SBUS, Spektrum and PWM receivers in
every firmware image.
PIOS_USART driver:
- Now handles its own low-level IRQs internally
- If NULL upper-level IRQ handler is bound in at board init time
then rx/tx is satisfied by internal PIOS_USART buffered IO routines
which are (typically) attached to the COM layer.
- If an alternate upper-level IRQ handler is bound in at board init
then that handler is called and expected to clear down the USART
IRQ sources. This is used by Spektrum and SBUS drivers.
PIOS_SBUS and PIOS_SPEKTRUM drivers:
- Improved data/API hiding
- No longer assume they know where their config data is stored which
allows for boot-time alternate configurations for the driver.
- Now registers an upper-level IRQ handlerwith the USART layer to
decouple the driver from which USART it is actually attached to.
This separates the RTC device and interrupt handling
from the devices that rely on the tick notifications.
Drivers can now register tick notification functions
that will be called on each RTC tick event.
All receivers now fall under the same driver API provided
by pios_rcvr.c.
This is part of a larger sequence of commits that will
switch the receiver selection over to boot time dynamic
configuration via UAVObjects.
Also implement some ordering (quite ugly still) in the module init and task creation order so we can decide which module to start/init first
and which module to start/init last.
This will be replaced/adapter with the uavobject list later (once it's implemented).
reserving some space for module init and task create parameters to customize module/task creation (this will be usefull once we get the list and customization from customer).
Changes have been made for OP and CC. Tested comped with CC,OP, sim_posix.
Only ran on bench with CC for couple of minutes (code increase expected but no dropping of stack which is good).
This gives task creation at the time wherethe all heap is available.
heap reamining is low (about 500) but stacks can be ajusted (specially the 200 bytes from system) to give the level close to 1Ko if needed.

- create linker section for those <module>Initialize()
- later this list will incorporate parameters as well. (this probably will be more a OP feature to swap/remove/delete module on the fly.
- this is not done at compile time anymore by Makefile.
- this will allow us to have control on the module start at run-time (not implemented but build the ground for it).
- this simplify the startup (Part of code re-org).
- this change does not affect sim_posix and win32 (since they don't need that)
- ensure it's compiling for PiOS.posix
- port to PiOS.win32 but not tested (not compiled)
- tested on CC
- compile on OP.
- this free ~200 bytes.
- current avalable bytes (is we keep the same remaining bytes on the stack than before) is easily passed the 1.2Ko mark on CC with new gcc (4.5.2)
- this does not include init-reorg for each module (I still think more can be freed)
I managed to test CC with heap2 changes and the init stack claimed back to heap once scheduler starts.
the changes of this commit are OP related (just cleanup on CC side):
Arch specific stuff (in reset vector) to hide this from portable code:
- switch back to MSP stack before starting the scheduler so that the sheduler can use the IRQ stack (when/if needed).
- call the C portable function in heap2 to claim some stack back (the number to claim is taken from linker file).
- start the scheduler from reset vector (I move this here from main because it make sense to not go back to C (so that I don't need to copy the rolled stack in case the sheduler returns). This make it more clean.
- Also I have added the call to the mem manager if sheduler return. that way, we don't reset indefinitely if memory runs out. We will go to this handler and figure things out (right now, it's just looping but at least not rebooting. Probably trap NMI would be better (later improvement).
Macros for JTAG program and wipe for each target are now
provided in firmware-defs.mk.
The _wipe target for each firmware and bootloader image will
erase either the bootloader (bl_*_wipe) or firmware (fw_*_wipe)
bank.
The USE_BOOTLOADER compile flag was only being used
to determine where the ISR vector table was located.
Provide this explicitly from the linker since it knows
exactly where it is putting the ISR vector table.
- New macros for fw, bl and bu rules in top-level make
- Per-board info factored into make/board/*/board-info.mk
- Per-board info now shared btw. fw, bl and blupd for each board
- BOARD_TYPE, BOARD_REVISION, BOOTLOADER_VERSION, HW_TYPE
- MCU, CHIP, BOARD, MODEL, MODEL_SUFFIX
- START_OF_BL_CODE, START_OF_FW_CODE
- blupd_* goals renamed to bu_*
- all_blupd goal renamed to all_bu
- firmware goals renamed to fw_*, board name goals are preserved
- bu_*_program now writes updater to correct address for all boards
- BL updater firmware builds now produce .opf format including
version info blob.
- BL updater firmware name now includes board name.
- INS makefile brought up to date w.r.t. linker scripts
This is done by separating PyMite-dependent sources and making them
dependent on autogenerated python code. This was tested with make -j
on Windows and worked fine. It failed with errors otherwise:
In file included from ../Libraries/PyMite/vm/class.c:28:
../Libraries/PyMite/vm/pm.h:198: fatal error: pmfeatures.h: No such file or directory
This change is made up of a number of tightly coupled
changes:
- Deprecate the use of the USE_BOOTLOADER command-line
option. It is now hard-coded in each Makefile.
Overriding it on the command line is not allowed.
- Split apart the memory declaration and the section
declaration in all linker files (*_memory.ld and
*_sections.ld).
- Describe the split between bootloader and app sections
of flash in each board's _memory.ld file.
- Change program target to selectively erase flash so
that the installed bootloader is preserved across even
JTAG programming operations.
- All elf files are built with debug symbols and are not
stripped. This should help debugging with gdb. The
images programmed on the boards are all .bin files now
which do not include symbols.
The .bin.o rule places the contents of a raw .bin file
into an .o file wrapped within fixed symbols for start
and end. This can be used to embed a binary file inside
of an executable.
The symbols for the embedded binary blob are:
_binary_start
_binary_end
_binary_size
NOTE: The way the .bin.o rule is currently written, you
can only embed one binary blob in an executable since the
symbol names will collide if you add multiple blobs. This
limitation is easily removed later if necessary.
Also change AttitudeActual to update at 10Hz rather than 2 Hz. The increased bandwidth is minimal and the resulting "polish" that it adds to the look-and-feel of the GCS is signifcant.
firmware include and delete all the extra foss-jtag config files. There is now
a legacy file for the revA board a second for AHRS that changes the port
Warning: The memory utilization when importing objects is unacceptably high making it unusable in the flight code at this point. It can be however used with the SITL simulator. Some more investigation is needed to understand why several kb of memory are used each time a module is imported (even before any functions are called or objects from the module are created).
