4mb flash boards of ESPs disable alarm and bleio in favor of dual bank and OTA. Let's switch this for 10. To do so, we need to remove all CIRCUITPY_LEGACY_4MB_FLASH_LAYOUT. This will move all boards to a non-ota partition scheme. We can do all non-S2 and S3 boards because they require a TinyUF2 update.

circuitpython/ports/espressif/mpconfigport.mk

Lines 280 to 294 in ea91e38

# We used to default to OTA partition layout but are moving away from it so that
# BLE and alarm can be included. This setting prevents the partition layout from
# changing.
ifeq ($(CIRCUITPY_LEGACY_4MB_FLASH_LAYOUT), 1)
ifeq ($(IDF_TARGET_ARCH), xtensa)
CIRCUITPY_ALARM ?= 1
else
CIRCUITPY_ALARM = 0
endif
CIRCUITPY_DUALBANK = 1
CIRCUITPY_BLEIO ?= 0
CIRCUITPY_SETTABLE_PROCESSOR_FREQUENCY = 0
else
CIRCUITPY_SETTABLE_PROCESSOR_FREQUENCY = 1
endif
