Add basic support for SBC-T43: a CM-T43 based single board computer.
CM-T43 is an AM437x based System-on-Module designed to serve as a building
block in embedded applications. SBC-T43 is composed of CM-T43 module on
top of the SB-SOM-T43 baseboard.
Basic support includes UART, GPIO, and I2C.

Please get rid of the extra line at the end of the file.. It will cause
whitespace warnings when applying and will also cause issues applying
other changes at the end of the file if they rely on the extra line.
And check the whole series, thanks :) It will make my life a bit easier.
And the Subject line should start with "ARM: dts: ..." for the unified
look.
Regards,
Tony

CM-T43 has an on-board EEPROM on i2c bus 0. Add it to the device tree.

Add PMIC support for CompuLab cm-t43 module. For now we keep all regulators
enabled until this could be refined with power management support.

CM-T43 has an on-board 2MB SPI-flash which stores U-Boot and the U-Boot
environment. Add it to the device tree.

One of the CompuLab cm-t43 configurations comes with on-board NAND flash as
primary storage. It is partitioned into kernel, dtb, and rootfs partitions.
Add it to the device tree.

CM-T43 comes with 2 ethernet ports connected to the cpsw subsystem, which
has 2 modes of operation: switch mode and dual emac mode.
Add the relevant muxing and set it up to work in dual emac mode by
default.

CompuLab SB-SOM baseboard is a carrier board for multiple arm-based SoMs.
It currently supports (with minor adjustments to assembly) CM-T43, CM-T54,
and CM-QS600 modules. It is a building block in the SBC-T43 single board
computer, which consists of cm-t43 on top of sb-som-t43.

You're correct about it being optional though.

On SBC-T43 the mmc1 interface is connected to an SD-Card slot.
Add the necessary muxing and configuration to the device tree.
