* tree/: Rename 'internal_delay()' to 'default_delay()'Edward O'Callaghan2022-12-121-1/+1
| | | | | | | | | | | | | | | 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'Callaghan2022-12-121-1/+1
| | | | | | | | | | | | | | 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.

* tree: provide flashrom context into programmer_delay()Alexander Goncharov2022-10-171-1/+1
| | | | | | | | | | | | | | | | | Modify the `programmer_delay` function signature to allow passing the flashrom context. Programmers that depend on internal delay should provide NULL as a context. The use of this function parameter will be introduced in CB:67393.

* drivers/: Make 'fallback_{un}map' the default unless definedEdward O'Callaghan2022-10-081-2/+0
| | | | | | | | | | | | | | | | | | | Drop the explicit need to specify the default 'fallback_{un}map' callback function pointer from the 'programmer_entry' struct. This is a reasonable default for every other driver in the tree with only a select few exceptions [atavia, serprog, dummyflasher and internal]. Thus this simplifies driver development and paves way to remove the 'programmer' global handle.
