* mtd: spi-nor: fix format specifier in debug messageAhmad Fatoum2024-02-011-2/+2
| | | | | | | | | | | | | The type size_t is to be printed with the %zu modifier as it's not necessarily typedef'ed as unsigned long, even if for barebox purposes, the sizeof(size_t) is always equal to sizeof(ulong). Building the dw-ospi-nor driver for 32-bit warns about this, so fix that.

* treewide: add MODULE_DEVICE_TABLE markersAhmad Fatoum2023-06-131-0/+1
| | | | | | | | | | | | | | | | Syncing device trees with Linux upstream can lead to breakage, when the device trees are switched to newer bindings, which are not yet supported in barebox. To make it easier to spot such issues, we want to start applying some heuristics to flag possibly problematic DT changes. One step towards being able to do that is to know what nodes barebox actually consumes. Most of the nodes have a compatible entry, which is matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE point at it for future extraction.

Thus retval is incremented in each loop cycle for each spi_nor_write() call without ever resetting it.

This becomes apparant only if the calling function actually compares len and retlen (e.g. mtd_peb_write() ). Otherwise wrong data is written: $ memcpy -s /dev/prng -d prng_data 0 0 10k $ erase /dev/mtd0.mypart $ cp prng_data /dev/mtd0.mypart $ memcmp -s prng_data -d /dev/mtd0.mypart 0 0 memcmp returned "files differ" before, with this patch it returns "OK".

Besides, this patch also introduces a new 'struct spi_nor_flash_parameter' telling the spi-nor framework about the hardware capabilities supported by the SPI flash memory and the associated settings required to use those hardware caps. Then, to improve the readability of spi_nor_scan(), the discovery of the memory settings and the memory initialization are now split into two dedicated functions. 1 - spi_nor_init_params() The spi_nor_init_params() function is responsible for initializing the 'struct spi_nor_flash_parameter'. Currently this structure is filled with legacy values but further patches will allow to override some parameter values dynamically, for instance by reading the JESD216 Serial Flash Discoverable Parameter (SFDP) tables from the SPI memory. The spi_nor_init_params() function only deals with the hardware capabilities of the SPI flash memory: especially it doesn't care about the hardware capabilities supported by the SPI controller. 2 - spi_nor_setup() The second function is called once the 'struct spi_nor_flash_parameter' has been initialized by spi_nor_init_params(). With both 'struct spi_nor_flash_parameter' and 'struct spi_nor_hwcaps', the new argument of spi_nor_scan(), spi_nor_setup() computes the best match between hardware caps supported by both the (Q)SPI memory and controller hence selecting the relevant settings for (Fast) Read and Page Program operations.

Unfortunately they do not fit in the current spi_controller model and usually have drivers placed in drivers/mtd/spi-nor which are only supporting SPI NORs and not SPI memories in general. This is an attempt at defining a SPI memory interface which works for all kinds of SPI memories (NORs, NANDs, SRAMs).

| | | | | | | | | | | | | | | | | | | | | | | | | | Sync up the driver with the original linux v4.7 driver version. As only Quad-SPI mode is/was supported, the function was not ported in the initial move to barebox. To make future synchronizations with the kernel driver easier, add this function and reorder the functions in the driver accordingly.
