* 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.

* 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.

* drivers/: Make 'internal_delay' the default unless definedEdward O'Callaghan2022-09-271-1/+0
| | | | | | | | | | | | | | | | | | | Drop the explicit need to specify the default 'internal_delay' callback function pointer in the programmer_entry struct. This is a reasonable default for every other driver in the tree with only the two exceptions of ch341a_spi.c and serprog.c. Thus this simplifies driver development.

* mediatek_i2c_spi.c: Add allow_brick=yes programmer paramEdward O'Callaghan2022-07-301-0/+37
| | | | | | | | | | | | | | | | | | | Currently i2c programmers do not have a safe allow listing mechanism via board_enable to facilitate fully qualified chip detection. Since i2c addresses alone can overlap a user may make the mistake of using the wrong programmer. Although unlikely, it is within the realm of possibility that a user could accidently somehow program another chip on their board.

* mediatek_i2c_spi: Use new API to register shutdown functionAlexander Goncharov2022-07-151-4/+2
| | | | | | | | | | | | | | | | | | | This allows programmer to register shutdown function in spi_master struct, which means there is no need to call register_shutdown in init function, since this call is now a part of register_spi_master. As a consequence of using new API, this patch also fixes resource leakage in case register_shutdown() would fail.

* spi: Add function to probe erase command opcode for all spi_masterAarya Chaumal2022-07-111-0/+1
| | | | | | | | | | | | | | | | | | | | Add a field, probe_opcode, to struct spi_master which points to a function returning a bool by checking if a given command is supported by the programmer in use. This is used for getting a whitelist of commands supported by the programmer, as some programmers like ichspi don't support all opcodes. Most programmers use the default function, which just returns true. ICHSPI and dummyflasher use their specialized function.
