[PATCH v4 0/3] Add support for all variants of the phyCORE-i.MX93 SOM
The phyCORE-i.MX 93 is available in various variants (e.g. different ram sizes, eMMC HS400 yes/no). It's eeprom contains information which features the existing module supports.
Extend the existing board-code to support all the SOM variants. The spl/u-boot evaluates the eeprom information and enables supported features accordingly. The resulting spl and u-boot binary is able to boot each phyCORE-i.MX 93 SOM variant on each carrier board.
Changes in v4:
patch #1: - none changes
patch #2: - add missing pinctrls for eMMC 100mhz and 200mhz
patch #3: - none changes
Changes in v3:
patch #1: - none changes
patch #2: - remove unwanted dts node eepromid - correct typo in doc (PHYTEC_IMX93_VOLTAGE_3V3) - improve enum code-style (phytec_imx93_option_index)
patch #3: - add comment about SoM-scope to imx93-phyboard-segin-u-boot.dtsi - rebase to the latest master - adapt doc according to new defconfig
Changes in v2:
patch #1: - remove multiple blank lines - add update of 1GB ram timings to commit message
patch #2: - encapsulate handling of feature flag VOLTAGE into own function - move definition of enum phytec_imx93_ddr_eeprom_code into header file
patch #3: - just rename imx93-phyboard-segin_defconfig and add needed CONFIGs, instead of creating an entirely new second defconfig - remove wrong comment from imx93-phyboard-segin-u-boot.dtsi - improve commit message

The phyCORE-i.MX 93 is available with a 1GB ram chip or a 2GB ram chip. Add the ram timings for the 2GB chip, in form of a diff compared to the existing LPDDR4X 1GB timings. With that, the SPL can select the appropriate timings at startup. Update also the 1GB ram timings with new version of the DDR Tool.

The phyCORE-i.MX 93 is available in various variants. Relevant variant options for the spl/u-boot are: - with or without HS400 support for the eMMC - with 1GB ram chip, or 2GB ram chip
The phyCORE's eeprom contains all information about the existing variant options. Add evaluation of the eeprom data to the spl/u-boot to enable/disable HS400 and to select the appropriate ram configuration at startup.

The phyCORE-i.MX 93 is available in various variants. Relevant variant options for the spl/u-boot are:
- with or without HS400 support for the eMMC
- with 1GB ram chip, or 2GB ram chip
The phyCORE's eeprom contains all information about the existing variant options. Add evaluation of the eeprom data to the spl/u-boot to enable/disable HS400 and to select the appropriate ram configuration at startup.

Changes in v4:
- add missing pinctrls for eMMC 100mhz and 200mhz
Changes in v3:
- remove unwanted dts node eepromid
- correct typo in doc (PHYTEC_IMX93_VOLTAGE_3V3)
- improve enum code-style (phytec_imx93_option_index)
Changes in v2:
- encapsulate handling of feature flag VOLTAGE into own function
- move definition of enum phytec_imx93_ddr_eeprom_code into header file

Hi Christoph,

The phyCORE-i.MX 93 is available in various variants. Relevant variant options for the spl/u-boot are:
- with or without HS400 support for the eMMC
- with 1GB ram chip, or 2GB ram chip
The phyCORE's eeprom contains all information about the existing variant options. Add evaluation of the eeprom data to the spl/u-boot to enable/disable HS400 and to select the appropriate ram configuration at startup.

Changes in v4:
- add missing pinctrls for eMMC 100mhz and 200mhz
Changes in v3:
- remove unwanted dts node eepromid
- correct typo in doc (PHYTEC_IMX93_VOLTAGE_3V3)
- improve enum code-style (phytec_imx93_option_index)
Changes in v2:
encapsulate handling of feature flag VOLTAGE into own function
move definition of enum phytec_imx93_ddr_eeprom_code into header file

The difference in the values is due to different drive-strength settings per pin. The values are the result of measurements we did for the eMMC interface. There, we adjusted each pin's drive-strength to get it's best signal quality.

Thanks for the explanation. So you measured also the 200 MHz case? Because there are no differences between the data pins.

Could you please explain why the pin configuration for 100 MHz of DATA0 & DATA2 is different from the other data pins?
The difference in the values is due to different drive-strength settings per pin. The values are the result of measurements we did for the eMMC interface. There, we adjusted each pin's drive-strength to get it's best signal quality.
Thanks for the explanation. So you measured also the 200 MHz case? Because there are no differences between the data pins.
Yes, we measured also for 200 MHz. There the same value was perfect for all pins.

Great, I'm fine with the whole series.
The phyCORE-i.MX 93 is available in various variants (e.g. different ram sizes, eMMC HS400 yes/no). Enable hardware introspection for the imx93-phyboard-segin_defconfig, so that during startup the SOM module variant can be detected, and the hardware can be configured accordingly. The resulting SPL and u-boot binary shall able to boot each phyCORE-i.MX 93 module variant on each carrier board. Finally rename imx93-phyboard-segin_defconfig to imx93-phycore_defconfig, to highlight its SOM scope.

Extend the existing board-code to support all the SOM variants. The spl/u-boot evaluates the eeprom information and enables supported features accordingly. The resulting spl and u-boot binary is able to boot each phyCORE-i.MX 93 SOM variant on each carrier board.
Applied all for -next, thanks.
