Newly Ported to libv2

• MemoryExt, PIO, Bootrom
• Library modules

MCU2

• Add bus performance measurement codes.
• Simplify (shorten) names of exceptions (IRQ and system exceptions).
• Add definitions of exception priorities.

MemoryExt

• Read procedure end address from meta data in the resource block, in lieu of scanning the memory.

PIO

• Update Init to work with two or three (or more) PIO devices (same concept as used for UARTs, SPIs, and timers)

Bootrom

• Only ported for RP2040 for now.
• Changes in RP2350 need a closer look first.

Example Programs

Additional example programs have been ported to run on both MCUs:

• CodeLoading
• StackUsage
• PIOsquare

BootromAccess.mod has been ported, too, but only for the RP2040; see above.
