The Gateworks Venice product family consists of several boards based on the i.MX 8M Mini SoC.
A challenge I've had with this is that the board model information is stored in an I2C based EEPROM that must be read to know what PMIC is on the board in order to adjust certain power rails before DRAM init is called. I found this to be a challenge in the SPL as the SPL does not free memory thus the conceprt of calling dm_uninit() followed by dm_init_and_scan() to change dt's live in the SPL runs out of memory. Therefore I can't rely on DT/DM within the SPL for things that may differ board to board.
Best Regards,
Tim --- v3: - drop already merged patches from series - add reference to Linux version files were pulled from in commits - fix accidental change to TARGET_IMX8MN_EVK - gsc.h: remove unused MAX6642 defines from - power_init_board: fix PMIC access by using dm_i2c
v2: - drop pmic patch that was already merged - add imx_tmu patch - update common/image patch as requested
