[platform] Amiga port (m68k)#511
Conversation
Tested on real hardware and under emulation; combinations of accelerated
and stock A500, A600, and A1200. All CPU models are supported, although
060 requires being built with 'M68K_CPU = 68060'. Current default target
is 68000, for greatest compatibility.
Features and hardware support:
- Basic 1bpp display driver
- Keyboard driver
- Serial console support
- Timer hardware driver
- Custom bootloader
- Heap arena size is based on detected chip RAM size
Current limitations:
- Floppy boot only, no IDE/ATA (tested with Gotek, should work with real disk)
- Only chip RAM supported. Boots with Fast Mem present, but doesn't
utilise it.
- Basic graphical abilities, room for improvements in acceleration
and colour depth.
- Early kernel boot output only present on serial console, though I
believe this is due to the nature of the current gfxconsole design.

Updated force push is from a few files that were missed. |

Looks pretty good! Will need to figure out what to do about xdftool though. I dunno how it passed the CI since it seems like it should have failed when building the m68k targets... |

Oh interesting, with script/buildall it'll simply skip it because of the $(error) in the platform file. An unintended consequence, but actually accomplishes the task but only when selecting an architecture. If regular buildall it will still fail. |

I've put together some code that can generate a valid ADF header and checksum. I'll update the PR once I've tested some more and integrated it in to the build process. This way we don't have to mess around with potentially pulling in Python and things in the CI runners. |
