Kevin O'Connor 3f3713ee97 Kconfig: Move SERIAL, USBSERIAL, and CANSERIAL definitions to src/Kconfig
There is no need to define these options in every board Kconfig file.

Kevin O'Connor 689231df3a stepper: Add support for stepping on both edges of a step pulse
Add an optimized step function for drivers that support stepping on
both rising and falling edges of the step pin.  Enable this
optimization on 32bit ARM micro-controllers.  Automatically detect
this capability in the host code and enable on TMC drivers running in
SPI/UART mode.

Michael Kurz efbb704522 lpc176x: Fix wrong inital value at PWM setup
This fixes a PWM going to full scale output when a initial value != 0 was
given. The output was on 100% until another update occurred.

This change enables the PWM counter before setting the channel values.

Fixes KevinOConnor/klipper#4559

Kevin O'Connor 45cd3543e3 lpc176x: Use full peripheral clock speed; fix UART interface
Commit ae89a659 caused a regression in the lpc176x UART handling.
After that commit the UART clock divisor would need to be 6.25 on
lpc1768 or 7.5 on lpc1769, but the code only supports whole numbers.

Set the PCLKSELx registers at startup and return to using full speed
peripheral clocks.

speed (25Mhz or 30Mhz) so that this register does not need to be

Kevin O'Connor faeaa54925 armcm_boot: Use armcm_main() instead of main() to start board code
The main() function has a special meaning to gcc and using it can
result in different code generation.  Use armcm_main() to avoid that.

Also, invoke SystemInit() from the board specific armcm_main() code.
This gives the board code more control over board initialization.

Kevin O'Connor e26d1a3567 i2ccmds: Pass the i2c address as a 7-bit number (0-127)
The sam3 i2c code and the linux code use a 7-bit i2c address, while
the avr, lpc176x, and samd21 i2c code uses an 8-bit address with the
least significant bit always zero.  A similar issue occurred in the
host code (sx1509.py and replicape.py use 7-bit addresses while
uc1701.py and mcp4451.py use 8-bit addresses).

Consistently use 7-bit addresses in all the code.  This breaks
compatibility between host and mcu software, so make a change to the
config_i2c command to force users to synchronize software updates.
This also breaks common Smoothieboard configs, so update the mcp4451
code to validate the i2c_address.
