* spi: Make 'default_spi_write_aai' the default unless definedEdward O'Callaghan2022-12-211-1/+0
| | | | | | | | | | | | | | | | | | | A NULL func pointer is necessary and sufficient for the condition `NULL func pointer => default_spi_write_aai' as to not need this explicit specification of 'default'. Therefore Drop the explicit need to specify the 'default_spi_write_aai' callback function pointer in the spi_master struct. This is a reasonable default for every other driver in the tree with only a few exceptions. This simplifies the code and driver development.

* tree/: Rename 'internal_delay()' to 'default_delay()'Edward O'Callaghan2022-12-121-7/+7
| | | | | | | | | | | | | | | The non-custom driver programmer delay implementation 'internal_delay()' is unrelated specifically to the 'internal' programmer. The delay implementation is simply a platform-agnostic host delay implementation. Therefore, rename to simply default_delay().

* tree/: Replace NULL-case of programmer_delay() with internal_delayEdward O'Callaghan2022-12-121-7/+7
| | | | | | | | | | | | | | Replace `programmer_delay(NULL, [..])` calls with direct `internal_delay([..])` dispatches explicitly. Custom driver delays remain hooked as well as core flashrom logic. The NULL base case of 'programmer_delay()' then becomes a condition to validate for layering violations or invalid flash contexts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the USB SPI V2 protocol and its documentation. The protocol version number uses the bInterfaceProtocol field in USB to identify which device to use, this enables us to support both V1 and V2 with the same host. The USB SPI V2 protocol adds the ability to perform multi-packet USB SPI transfers. This results in fewer USB messages exchanged, larger SPI transfers, and faster flashing speeds.

This process repeats 3 times before we return the last error code. Intermediary problems are reported in the status code.
