+Summary
+=======
+
+This document covers various features of the 'BAV335x' board build.
+For more information about this board, visit http://birdland.com/oem
+
+
+Hardware
+========
+
+The binary produced supports the bav335x Rev.A with 10/100 MB PHY
+and Rev.B (default) with GB ethernet PHY.
+If the BAV335x EEPROM is populated and programmed, the board will
+automatically detect the version and extract proper serial# and
+mac address from the EE.
+
+
+Customization
+=============
+
+The following blocks are required:
+- I2C, to talk with the PMIC and ensure that we do not run afoul of
+  errata 1.0.24.
+
+When removing options as part of customization,
+CONFIG_EXTRA_ENV_SETTINGS will need additional care to update for your
+needs and to remove no longer relevant options as in some cases we
+define additional text blocks (such as for NAND or DFU strings).  Also
+note that all of the SPL options are grouped together, rather than with
+the IP blocks, so both areas will need their choices updated to reflect
+the custom design.
