Add input support, examples, SIO/PADS ownership Sorry this is a large commit :( This adds support for input pins, including pulling them high or low. It also adds two examples: the start of a classic blinky LED example, and an example for reading input. 2021-04-24 16:18:57 -05:00			`MEMORY {`

Make BSPs provide boot2 as a default feature (#153) * Add boot2 feature. Add boot2 linkage into each BSP optional on feature * Enable boot2 feature in BSPs by default. Remove boot2 decl from all BSP examples * Add EXTERN in memory.x for BOOT2_FIRMWARE, rename bootloader static slice to BOOT2_FIRMWARE * Update new examples and itsy_bitsy BSP to use boot2 feature * Remove boot2 as a dev-dependency for the BSPs, no longer needed * Add no_mangle BOOT2_FIRMWARE to adafruit_macropad * Fix itsy-bitsy blinky - it wasn't using the BSP, so it didn't get BOOT2_FIRMWARE linked in 2021-12-05 01:00:09 +11:00			`EXTERN(BOOT2_FIRMWARE)`
