with the help of xvilka, idwer and roysjosh i did my first board enable
today. it was a standard awdflash RE job; the disassembly is on
xvilka's gobby server, if you are interested.
we have identified two parts. the first is equivalent to the
enable_flash_sb400 chipset enable, the second one sets a gpio line of
the sb400 to one.
this was confirmed by the sb7xx datasheet (thanks roysjosh for the
hint!); see amd document 43009
i have attached the patch, which is not for inclusion yet (still
the main reason i am posting now it the question if i should generalize
this. i was thinking about something like intel_ich_gpio_set.
because the gpio registers of the sb400 and sb7xx are spread out quite
randomly we would need a mapping including:
- gpio# (can be array index but i would include it for a sanity check)
- output enable register address
- output enable register bit
- output register address
- output register bit
since this is the first time we need a board enable for this
southbridge family i am wondering if it is worth it at all... but i
would work on it if you wish.
Kind regards/Mit freundlichen Grüßen, Stefan Tauner
