+Given that all of the above boards are reference platforms (and the
+Beaglebone platforms are OSHA), it is likely that this platform code and
+configuration will be used as the basis of a custom platform. It is
+worth noting that aside from things such as NAND or MMC only being
+required if a custom platform makes use of these blocks, the following
+are required, depending on design:
+- GPIO is only required if DDR3 power is controlled in a way similar to
+ EVM SK
+- SPI is only required for SPI flash, or exposing the SPI bus.
+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.
