mtd: spi-nor: expose internal parameters via debugfs

2022-05-09T11:25:22Z

There is no way to gather all information to verify support for a new flash chip. Also if you want to convert an existing flash chip to the new SFDP parsing, there is not enough information to determine if the flash will work like before. To ease this development, expose internal parameters via the debugfs.

mtd: spi-nor: move spi_nor_write_ear() to winbond module

2022-05-02T09:12:00Z

The "Extended Address Register" is winbond specific. If the flash is larger than 16MiB and is used in 3 byte address mode, it is used to set the remaining address bits. Move the write_ear() function, the opcode macros and the spimem op template into the winbond module and rename them accordingly.

mtd: cfi_cmdset_0002: Use chip_ready() for write on S29GL064N

2022-04-28T08:17:10Z

Since commit dfeae1073583("mtd: cfi_cmdset_0002: Change write buffer to check correct value") buffered writes fail on S29GL064N. This is because, on S29GL064N, reads return 0xFF at the end of DQ polling for write completion, where as, chip_good() check expects actual data written to the last location to be returned post DQ polling completion. Fix is to revert to using chip_good() for S29GL064N which only checks for DQ lines to settle down to determine write completion.

mtd: fix 'part' field data corruption in mtd_info

2022-04-21T07:29:05Z

Commit 46b5889cc2c5 ("mtd: implement proper partition handling") started using "mtd_get_master_ofs()" in mtd callbacks to determine memory offsets by means of 'part' field from mtd_info, what previously was smashed accessing 'master' field in the mtd_set_dev_defaults() method. That provides wrong offset what causes hardware access errors. Just make 'part', 'master' as separate fields, rather than using union type to avoid 'part' data corruption when mtd_set_dev_defaults() is called.
