[PATCH 0/4] Add Gateworks Venice board support

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

  Respect that some compression algos can be enabled separately for SPL
