BBB cape EEPROM and FDT overlays


There exists cape expansion EEPROM format [1]. However, currently only first 250 bytes are in use. The question is the following. Is it possible to extend this format to allow storing FDT overlay for the particular cape? Then u-boot could read the overlay and patch the main board FDT.

Alternatively, u-boot could recover the used peripheral via the “Pin usage” field and then enable devices using board_fix_fdt()
