Hello Fabio,
Thanks for the review!
It would also be helpful to add doc/board/variscite/imx93_var_som.rst that explains how to build U-Boot for this board, how to get the firmware, ATF, binaries, etc, and how to flash it to the boot medium.
For now, I am testing the bootloaders I produce using those instructions: https://variwiki.com/index.php?title=Yocto_Build_U-Boot&release=mx93-yoc...
I understand that it would be nice to have u-boot do the image construction with the firmware, ATF and so on, like implemented on imx8.
Do you think that it could be done in a follow-up patch, once imx93-var-som support is merged?
Please also submit the imx93-var-som-symphony.dts support to Linux so that it can get reviewed by the DT folks.
Done here: https://lore.kernel.org/linux-devicetree/20231227170919.8771-1-othacehe@gnu....
To not block the board support, I suggest sending a v2 without PTN5150 support for now.
OK.
+/* Using ULP WDOG for reset */ +#define WDOG_BASE_ADDR WDG3_BASE_ADDR
Is this needed now that we use DM?
That specific define is needed as the ulp_wdog driver seems to require it. I removed all the other unneeded defines in v2.
Thanks,
Mathieu
