2021-02-18core: add bit_transpose functionJeff Epler
.. this version can only handle exactly 8 bits "across". The restriction may be relaxed in a future revision.

2021-02-17raspberrypi: implement os.urandomJeff Epler
Since the datasheet cast some doubt on the strength of the "rosc_hw->randombit", I use the SHA256 hash function to create a high quality random seed from random values of uncertain entropy, as well as to generate a sequence of random values from that seed using SHA256 as a cryptographically-secure random number generator. In practice, it produces over 100kB/s of random data which does not have any gross problems according to _PractRand_.

2021-02-12Enable protomatter on RP2040 buildsJeff Epler
Also found a race condition between timer_disable and redraw, which would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable or put a delay or print inside it. That's what pausing inside reconstruct fixes. So that the "right timer" can be chosen, `timer_allocate` now gets the `self` pointer. It's guaranteed at this point that the pin information is accurate, so you can e.g., find a PWM unit related to the pins themselves. This required touching each port to add the parameter even though it's unused everywhere but raspberrypi.

2021-02-08rp2pio: Transfer up to 32 bytes before checking background tasksJeff Epler
@Jerryneedell noticed that this problem affected strips short enough to not use the DMA peripheral, thanks for the hot tip! Instead of checking for background tasks after every byte transfer, try up to 32 transfers before attending to background tasks. This fixes the problem I was seeing on my 5-pixel circuit. Closes #4135.

2021-02-05Add SMPS mode pin to Raspi Pico pins.cMark Omo
Add SMPS mode pin to Raspi Pico pins.c; see section "4.3. Using the ADC" of the Pico datasheet for discussion. Driving this pin high forces the onboard regulator into a lower noise PWM mode.

2021-02-04raspberrypi: implement reset, reset_to_bootloaderJeff Epler
This makes all the following work: * normal microcontroller.reset() * reset into safe mode or UF2 bootloader via microcontroller.on_next_reset() * reset into UF2 bootloader via the "1200 baud trick" The implementation of reset_cpu is from micropython.
