Add support for platforms based on the Meerkat COM module. Includes support for the minimal reference platform called Kein Baseboard, which in fact is sufficient to run most existing Meerkat carriers.

There's an unnecessary blank line at the top of the file.

That should be pinmux_clear_tristate_input_clamping();

Most/all of these are related to not using the latest tegra-pinmux-scripts to generate the pin config table; see the comments on that below.

Can you please also add support for this board to tegra-pinmux-scripts, so that anyone can generate this file? That will also allow you to re-generate the file using the latest version of tegra-pinmux-scripts which will add (a) the missing "this file is auto-generated" notice, (b) the GPIO initialization table, (c) the MIPI padctl initialization table.

+CONFIG_CMD_EXT4=y
Relative to Jetson TK1, CONFIG_CMD_EXT4_WRITE is missing. Was that deliberate? I'd rather keep all the Tegra configs as similar as possible, at least in the upstream code.
+CONFIG_DM_I2C_COMPAT=y
That's not required on any Tegra board these days. Is it necessary?
+CONFIG_E1000=y
I notice that CONFIG_CMD_MII isn't present, yet Ethernet is. For consistency with other Tegra boards, does it make sense to add CONFIG_CMD_MII?
+CONFIG_USB_STORAGE=y
For Jetson TK1, this is defined in include/configs/jetson-tk1.h. I'd expect the two board configs to work the same way.
CONFIG_USE_PRIVATE_LIBGCC=y is missing.
