* tree: provide flashrom context into programmer_delay()Alexander Goncharov2022-10-171-6/+6
| | | | | | | | | | | | | | | | | 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.

* s25f.c: Fix undefined behaviour on shiftEvan Benn2022-10-081-4/+4
| | | | | | | | | | | | | | | | | dev_id, a uint8_t, was shifted left by 24 bits. After promotion to int, this results in shifting into the sign bit, which is undefined behaviour. Cast to uint32_t to prevent the promotion to signed int.

* spi25_statusreg: delete spi_read_status_register()Nikolai Artemiev2022-04-051-3/+7
| | | | | | | | | | | | | | | | | | | | | | | Delete the spi_read_status_register() function because the generic spi_read_register() function can be used instead. This patch also converts all call sites over to spi_read_register(). A side effect is that error codes are now properly propagated and checked.

* writeprotect, cli_classic: delete old writeprotect codeNikolai Artemiev2022-02-281-1/+0
| | | | | | | | | | | | | | | | | | | | | Delete writeprotect code that was previously extracted from the cros tree. This is the first of a series of commits adding writeprotect support. Following commits incrementally implement writeprotect operations, culminating in writeprotect support for three example chips: GD25LQ128, GD25Q32, and GD25Q256.

* s25f.c: Fix mismatched function definitionsAngel Pons2021-04-241-4/+2
| | | | | | | | | | | | | This was missed because `uint32_t` is `unsigned int` in most cases. However, it is not the case for DJGPP 6.1.0 for some reason. Tested with manibuilder, solves some build errors on the DJGPP target.

* s25f.c: implement probing and block erasers for SpansionNikolai Artemiev2020-12-031-0/+391
This adds support for Spansion 25Fxxxxx chips. These chips require their own probing logic because the first 6 bytes returned by RDID must be examined to identify the chip. New erase functions are required as the chips support multiple sector layouts, and the default layout must be changed to be able to erase the entire flash. Adapted from cros flashrom at `9c4c9a56b6a0370b383df9c75d71b3bd469e672d`.
