To: u-boot, upstream; +Cc: Christoph Stoidner
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 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

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.

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.

It doesn't look right to me. When you have to modify soc.c to add your own board config, then either there is a problem with the file and it should be fixed properly here or there is a problem with your board and it should be fixed in your board code. > #ifndef CONFIG_XPL_BUILD > int board_fix_fdt(void *fdt) > { > diff --git a/board/phytec/common/Kconfig b/board/phytec/common/Kconfig > index f394ace786..bc5511707a 100644 > --- a/board/phytec/common/Kconfig > +++ b/board/phytec/common/Kconfig > @@ -19,6 +19,14 @@ config PHYTEC_IMX8M_SOM_DETECTION > Support of I2C EEPROM based SoM detection.

The function board_fix_fdt() is an u-boot callback, that can be implemented by the board-code. It enables the board-code to modify the Device Tree. The modified device tree is then subsequently used by U-Boot. We need that in our board-code to enable or disable HS400 for the eMMC, depending of what module variant we detected from the information in the eeprom. Unfortunately, NXP has already implemented that function in their SOC-code, so it is no more available for the board-code. From my opinion, the best solution would be to move board_fix_fdt() from soc.c to all imx9 board codes that need it. Then that function is again available for the board code. My proposal: To avoid loosig the focus of that patchset we accept it now as it is here. After that, I will then take care to send another patchset to move board_fix_fdt() for all boards accordingly.

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.

That imx93-phycore_defconfig has no more dependency to the carrier board. Thats why I renamed it. The intention for the defconfig is that the resulting SPL and u-boot binary can to boot each phyCORE-i.MX 93 module variant on each carrier board.

That is why I am asking. This approach has served us well for a while. Most of our u-boot "boards" are designed from a SoM perspective. Also, customers typically use the initial carrier board as a reference, often following its interface configurations. So in most cases we are good to go. I'm not sure why you want to bring this up again. ^ permalink raw reply [flat|nested] 24+ messages in thread
