* armcm_boot: Add generic code for early board init on armcm machinesKevin O'Connor2019-08-221-0/+2
| | | | | | | | Add basic ARM Cortex-M C init code and build linker scripts to src/generic/ code. This can be used to simplify the various ARM board code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* armcm_timer: Improve comments on wrap_timer codeKevin O'Connor2019-07-271-3/+5

* armcm_timer: Support micro-controllers faster than 160MhzKevin O'Connor2019-07-241-0/+22

* armcm_timer: Unify udelay() implementationKevin O'Connor2019-06-091-0/+14
| | | | | | | Move the udelay() code from various arm board directories into the src/generic/armcm_timer.c code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* command: Always pass a string to the DECL_CONSTANT() macroKevin O'Connor2019-03-171-1/+1
| | | | | | | | Make it clear that the name of the constant being defined is a string. When the value being defined is also a string, use a new DECL_CONSTANT_STR() macro. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* armcm_timer: Add a generic timer mechanism for ARM CortexM3/M4 chipsKevin O'Connor2019-02-061-0/+136
The ARM CortexM3 (and later) chips almost always have a 32bit timer in the "Debug and Watch Trace" (DWT) unit which resides within the cpu core itself. This timer is generally faster to access than timers located on the chip's peripheral bus. When combined with the standard ARM SysTick timer it provides a (generally) portable mechanism to implement Klipper's software timer mechanism. It's generally also faster than using the vendor specific timers. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
