Implementation of the task module, a proto-os capable of running multiple tasks concurrently, with cooperative scheduling, stack-less tasks, internal timing management and power management. This implementation includes :

the task module itself, responsible for the tasks and the power management
the stk module responsible for configuring the systick of the cortex M3
the scb module responsible for managing the cortex m3 and in this case its sleep state
the pwr module responsible for managing the sleep state of the microcontroller except the cortex M3, and configuring access to the backup domain for the bkp module
the bkp module responsible for configuring the RTC

Remaining work on this implementation include calibrating the RTC when using the LSI wich will be done later since it would require the use of timers for which the driver is yet to be created

Write first API macros fb1c11132f

Define systick's registers 7ba9063d02

Implement systick module ddd05da6eb

Document systick module 7e69bfd89c

Implement task module 432310a52d

For now, most code is temporary to validate that the system can work as
envisionned. Optimisations and cleaning will be done shortly

Make stk_read function usable 34fb4dac76

This function used to return the raw current value, but that exposes the
prescaling used internaly

Remove priority parameter from tasks c09d2cda67

In the end, priorities are only usefull in preemptive systems. Here, it would
only garentee the execution order, which we don't care about most of the time

Create new delay module 7cb33f65a5

Simplify task module b7951f2211

Add back task features in a simplified way 173e16eb2e

Fix typo in task macros dd1756221d

Add API to access task's system time 93b383be49

Document the task module d5c70a3a04

Fix major reg bitfield issue 5e4d87474a

A while back, macros had to be put in place to avoid letting the
compiler directly use the bitfields. This was necessary because the
compiler used strb instruction which only write bytes. On the AHB bus,
byte writes are transformed into word writes by repeating the byte,
which caused mayhem in the registers. After a lot of research, turns out
the packed attribute stops the compiler from does optimal (word) writes
and isn't needed anyway. Removing them fixes the issue

Define PWR module's registers 9681755168

Define SCB module's registers 97dad53621

Implement SCB module 1741d47546

Fix typo in PWR registers 5c89df4324

Implement sleep modes 3e97d4fe7e

Add LSI configuration function to RCC 699569ec99

Implement RTC module's registers a02bcecaec

Ensure PWR is enabled before configuration 0b483c535b

Add RTC configuration to RCC module b37eb1dd6e

Implement RTC module's basic functionnalities 3e3d4d2bff

FUnctions need a cleanup and some details need be ironned, like the
clock management since the whole backup domain must be reset to
configure them

Move rtc control to new BKP module 507f1e6863

RCC's BCDR register has been moved to the BKP module since it is part of
the backup circuit and thus also aboeys some restrictions access-wise

Temporarily fix warning b1d25561b4

Document BKP module 80c027370b

Add missing file documentation 947df53ecb

Add openocd configuration ba9bc57a49

The target's debug would sometime get stuck while in low-power, making
it difficult to resume communications, even after hardware resets. Some
peripherals were also kept running when halted. This config should fix
these issues

Rework exti module to use a simpler API 7ab6622908

The "specific" lines configuration would not work due to index error in
the callback configuration. While fixing the error, simplifying the API
by moving the afio calls to the calling context seemed a cleaner way to
do things

Implement bkp's rtc alarm configuration 24e412446d

Since the alarm must be set each time it is to be used, a separated
function is a better fit

Integrate the RTC to the task module 89c81b8c42

Force the use of system's reset in openocd a4ca0d30c3

Using the system's reset avoids the debug getting stuck when the chip
enters low power. Hopefully this works all the time

Fix include issue in afio module bc4bab4704

Fix compilation warning in task module ebc7ad4235
