Two parts are considered variants here if one part name starts with the name
of the other, flash memory sizes are the same, flash page sizes are the same
and the number of interrupts are the same.
These assignments have been removed as they are redundant and only
imitate the single prog_modes = PM_... | PM_....; assignment. They
are still allowed in the grammar, and would still work.
flags now just hold parameters of the JTAG interface and some secondary
serial, parallel, pseudo parallel info. This separation brings clarity. It
used to be hard to augur whether a part has an ISP interface:
(part->flags & (AVRPART_HAS_PDI | AVRPART_AVR32 | AVRPART_HAS_TPI
| AVRPART_HAS_UPDI)) == 0 && (part->flags & AVRPART_SERIALOK) != 0
or had HVSP or HVPP capability, for that matter. Now it is just, eg,
part->prog_modes & PM_ISP
part->prog_modes & PM_HVPP
- Add prog_modes to part and programmer definitions; prog_mode is a bitwise
or of programming modes
+ PM_SPM: Bootloaders, self-programming with SPM/NVM Controllers
+ PM_TPI: t4, t5, t9, t10, t20, t40, t102, t104
+ PM_ISP: SPI programming for In-System Programming (typ classic parts)
+ PM_PDI: Program and Debug Interface (xmega parts)
+ PM_UPDI: Unified Program and Debug Interface
+ PM_HVSP: High Voltage Serial Programming (some classic parts)
+ PM_HVPP: High Voltage Parallel Programming (most non-HVSP classic parts)
+ PM_debugWIRE: Simpler alternative to JTAG (a subset of HVPP/HVSP parts)
+ PM_JTAG: some classic parts, some xmega
+ PM_aWire: AVR32 parts
- Add mcuid, a unique id in 0..2039, to part definition for urclock programmer
- Add n_interrupts, the number of interrupts, to part definition
- Add n_page_erase to part definition (# of pages erased during NVM erase)
- Implement a simple calculator in config_gram.y so numeric values can be
expressed as simple expressions such as PM_SPM | PM_UPDI
- Introduce a new method of assigning simple components to the grammar without
touching config_gram.y via an eligible-component list in config.c; numeric
expressions on the rhs of an assignment resolve to integer values
- Update documentation in avrdude.conf.in and avrdude.texi
