TNETV107X is a Texas Instruments SoC based on an ARM1176 core, and with a bunch on on-chip integrated peripherals. This patch adds support for the TNETV107X EVM board.

Do you really need board specific linker scripts? Or would one common linker script for all (or at least for most of the) boards be sufficient?

Is "davinci" correct here?
