Hi all,
Here are the patches for MAX 10 BMC core/SPI interface split and
addition of the PMCI interface. There are a few supporting rearrangement
patches prior to the actual split. In this version, the indirect register
access became part of the BMC PMCI module.
The current downside of the split is that there's not that much code
remaining in the core part when all the type specific definitions are
moved to the file with the relevant interface.
The patch set is based on top of the "fpga: m10bmc-sec: Fix probe
rollback" and commit dfd10332596e ("fpga: m10bmc-sec: Fix kconfig
dependencies") to avoid triggering conflicts.
v3:
- Move regmap indirect into BMC PMCI module
- Get rid of "generalization" of cmd offsets and values, back to v1 #defines
- Tweak Kconfig & Makefile
- Rename intel-m10-bmc-pmci to intel-m10-bmc-pmci-main
- Rework sec update read/write paths
- Sec update driver code effectively uses the SPI side code from v2
- Rename m10bmc_sec_write() to m10bmc_sec_fw_write()
- Rename flash_ops to flash_bulk_ops and make them optional
- Move flash MUX and flash_mutex handling into sec update driver
- Prevent simultaneous flash bulk write & read using flash_mutex
- Keep M10BMC_STAGING_BASE in header (now used in the sec update code)
- Rebased on top of leak fix "fpga: m10bmc-sec: Fix probe rollback"
v2:
- Drop type from mfd side, the platform info takes care of differentation
- Explain introducing ->info to struct m10bmc in commit message (belongs logically there)
- Intro PMCI better
- Improve naming
- Rename M10BMC_PMCI_FLASH_CTRL to M10BMC_PMCI_FLASH_MUX_CTRL
- Use m10bmc_pmci/M10BMC_PMCI prefix consistently
- Use M10BMC_SPI prefix for SPI related defines
- Newly added stuff gets m10bmc_spi prefix
- Removed dev from struct m10bmc_pmci_device
- Rename "n_offset" variable to "offset" in PMCI flash ops
- Always issue idle command in regmap indirect to clear RD/WR/ACK bits
- Handle stride misaligned sizes in flash read/write ops
