Change in flashrom[master]: ft2232_spi.c: Generalize GPIOL pin control

The existing arg "csgpiol", is intended to function as an additional "cs" signal, allowing pins to be set high but not low. This patch preserves the csgpiol arg for backward compatibility.

Change in flashrom[master]: ft2232_spi.c: release I/Os on shutdown
by Edward O'Callaghan (Code Review) 24 Jan '21

Edward O'Callaghan has submitted this change. ( https://review.coreboot.org/c/flashrom/+/49632 ) Change subject: ft2232_spi.c: release I/Os on shutdown ...................................................................... ft2232_spi.c: release I/Os on shutdown Reset FTDI I/O pins to high-Z (input) when shutting down. This allows other devices to use the SPI bus without having to disconnect the programmer. This change will introduce a backward incompatibility in the case where a user is relying on the state of FTDI outputs post-programming (eg. to disallow another device from driving CS low). However, there are likely more cases where releasing the SPI bus is the correct thing to do.
