2.2.2.1 QSPI Interface

The TMDS273GMEVM board has a 64 Mbit QSPI memory device (GD25B64CWAG from GigaDevice), which is connected to the MSS_QSPI interface of the AM273x SoC. This flash device is primarily meant to store the boot image, but can also serve as storage for other data if another boot mode is used.
