Hello,
this is v4 of patchset that adds support for U-Boot to parse MTD partitions from device-tree, and also improves support for SPI NOR access via the `mtd` command.
Small rebase was needed since last version.
Finally passing CI since LTO is now merged and can optimize away the code increase. CI at https://github.com/u-boot/u-boot/pull/55
Changes since v3: - rebased against current master (removed first patch, not needed anymore) - check for CONFIG_OF_CONTROL in addition to CONFIG_DM, since we are also using ofnode_* functions - match mtd's name in a separate function to make code more readable. Also add non-DM version of this name matching function, since #if macro must be used (otherwise CI will fail for configurations with disabled DM) - addressed Simon's comments about using IS_ENABLED instead of #ifdefs - added Miquel's Reviewed-by and Patrice's Tested-by to the whole series
Changes since v2: - addressed Pali's comments in patch that adds partition parsing (4/7 in this version): no check for whether the `compatible` property is present in a partition node and added comment explaining mask flags) - added 4 more patches: 1) adding ofnode_get_path() function 2) printing OF path in `mtd list` 3) in `mtd read <name> ...`, <name> can now also be DM's device name or OF path 4) the fact from 3) is added to `mtd help`
Changes since v1: - added tests of ofnode_get_addr_size_index() and ofnode_get_addr_size_index_notrans() as requested by Simon - the last patch now probes SPI NORs in both versions of mtd_probe_devices(), that is when MTDPARTS is enabled or disabled
