Teensy 4.1 Development Board

Generally a very nice addition to the lineup. I'm personally fascinated by the support for soldering on an additional RAM chip; depending on how painful it is to actually access that memory, the extra 8MB could finally be enough to run uclinux.

The ESP32 can do that too. Note that PSRAM is a lot slower than the embedded SRAM, so if you need to access that memory a lot, you're going to have a bad time.

Rest assured, when I'm trying to figure out whether I can coerce Linux into running on a board that was never meant to support such a thing, "slow" is a secondary concern:)

Apparently it's as simple as using a different offset in pointers when enabled!
