- CRITICAL: initialize Fine Pulse Generator prior to DDS (see comments in the code)
- temporarily disable gain scheduling in SoftPLL to speed up locking during development
- migrate printfs() to debug calls

dev/spi_flash: fixed incorrect read/write address (regression added while adding support for 4-byte address mode)

boards/ertm14: skeleton work on DDS sync to RF trigger. Decided we need a simple event system though, so this will be likely changed

dev/storage: temporarily disable SDB preformatted image (needs to be reworked to avoid binary linker sections)

dev/ep-pfilter: removed another special linker section and changed for an autogenerated header. Makefile needs to be fixed, though!

dev: replace eRTM14's dds_sync_unit with a more generic version from general-cores (fine_pulse_generator)
