Riku introduced three new patches:
* Add support for multiple chip selects. This allows you to
control multiple chips from the same clip, on systems with
dual flash setups, at least theoretically.
* Enable pull-up on unused chip selects - pull them high so
that chips you connect that to are deactivated while flashing
the target chip. This could be used on thinkpad W541 for
instance, where miso/mosi have 0ohm between them via the two
flash ICs. You could pull the other chip select high.
* Documentation for the above, in the pico-serprog readme.
This goes in tandem with a patch from Riku, present in the
recently integrated flashprog project, namely:
commit ddb6d926783d4f9cbee04c7392718ed8f89daa0e

serprog: Add support for multiple SPI chip selects
This functionality will therefore be present in the next
release of Libreboot.

riku committed a new patch, that fixes build errors
when PICO_DEFAULT_LED_PIN is not defined, on a given
board. in such cases, riku's new patch just disables
handling of the status LED, but LEDs continue to work
on boards where it is defined.

the new revision sets drive level to 12mA instead
of the default 4mA. 16-20mA is the maximum tolerated
level for data lines, on most flash ICs, so 12mA is
relatively safe.
riku did this a while ago, tested on pico pi.

notabug is unreliable, even as a backup.
why, just today, it was offline! all day.
i originally moved libreboot away from notabug,
to codeberg instead, but kept the notabug account
online, and i still push to it when it's online.
however, notabug seems to be in a terminal state
of neglect by its admins, so lbmk should not use it.
