samples per message block. This improves bandwidth efficiency.

Query the adxl345 message counter every 100ms so that accurate timing
can be obtained during measurements. This allows the adxl345 data to
be exported with timestamps while captures are running.

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.

The atmega328pb supports PORTE, but the current avr-libc toolchain
doesn't support the atmega328pb. So, for now, add support for PORTE
to atmega328p.

The atmega328pb has officially named these pins as PE2 and PE3, so use
that naming scheme instead of the previous Klipper invented names.

This implements SPI for the rp2040 target. All output groupings of both
SPI blocks are available for use.

This implements hardware PWM support for the rp2040. The maximum
value(100% duty) is set to 255 to match the other controllers. Cycle
time is clamped automatically, and uses the full 8.4 fractional range of
the rp2040 PWM block. This allows a maximum PWM frequency of 490kHz and
a minimum frequency of 1915 Hz.

The rp2040 doesn't have a chip ID, but the flash chip connected does. We
can get this ID by asking the flash chip directly, but doing so requires
disengaging the XIP layer, performing the interrogation of the flash
chip, and then re-enabling the XIP layer. This gives us a 64-bit unique
ID that we can use as our USB serial number.

In binutils 2.36 and above the -nostartfiles option is no longer
ignored. -nostartfiles is actually a gcc option, and so isn't supported
by ld. Earlier versions of binutils however had less error checking, and
thus just ignored the option.

adds basic uart, timer, gpio, and watchdog support.

Commit 6a3c357a incorrectly disabled support for USART3 on stm32f1 and

These commands were never used by the main code and are not
particularly helpful for debugging. Remove them to reduce code size -
in particular on the pru architecture.

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.
