This question is most probably about pin-configurations registers. I mean since QSPI is the same as SPI with more data bus-width (correct me if I'm wrong on this first assumption), then doesn't it mean that some pins can be configured to act as a QSPI peripheral?

It seems like a simple(?) DIY tweak to be able to implement QSPI communication by allocating/configuring a few more pins, and of course make/change things in the code, based on what a proper QSPI communication demands.

right?

Probably not, if it supports only spi then you could bit-bang quad-spi, but you won't have the speed of hardware controlled quad spi and dma. This could limit the bandwidth so if you need quad spi that is fast, then get a micro with hardware quad spi.

    \$\begingroup\$ thanks. I didn't know I was actually asking a question about the "bit-bang" procedure. \$\endgroup\$
