ARM: i.MX8MN: add i.MX8MN-EVK support
With driver support in place, we can now build and run barebox in the
i.MX8MN. Following tested working:
- Setting up DDR4 SDRAM
- Booting from SD-Card
- Booting from eMMC
- Updating barebox in SD-Card/eMMC boot partition
- USB Fastboot, ACM gadgets
- UART
- Early I2C with bd71837
- Ethernet
- Loading and communicating with TF-A
The resulting image supports both DDR4 and LPDDR4. They use different
PMICs, so probing the i2c addresses of them indicates what DRAM type
to setup. I have only tested this on a DDR4 EVK, but the LPDDR4 code
is equivalent to what's already used in barebox with i.MX8M Mini
and Plus, so it should work(tm).
Notably missing:
- boot from USB SDP doesn't work. early debug_ll doesn't indicate
that barebox PBL was actually entered.
This can follow later though.
