.. all the necessary steps to transform it into a padded, checksummed file are now done by the build system.

Since it is assigned by "?=", it should be the case that individual builds can override it.

I did not "test" this per se, but it gives the same content and checksum (except for the identifying comment with a path) as #4302.

Thanks! Want to switch the pico back to the qspi version?

That would be a good test, will do

Presumably, switching it to generic hurt performance a bit.

I verified that the build-raspberry_pi_pico/boot2_padded_checksummed.S
built file has the same checksum as the old
bs2_default_padded_checksummed.S
