33 * hymod configuration data - passed by boot code via the board information
34 * structure (only U-Boot has support for this at the moment)
36 * there are three types of data passed up from the boot monitor. the first
37 * (type hymod_eeprom_t) is the eeprom data that was read off both the main
38 * (or mother) board and the mezzanine board (if any). this data defines how
39 * many Xilinx fpgas are on each board, and their types (among other things).
40 * the second type of data (type xlx_mmap_t, one per Xilinx fpga) defines where
41 * in the physical address space the various Xilinx fpga access regions have
42 * been mapped by the boot rom. the third type of data (type xlx_iopins_t,
43 * one per Xilinx fpga) defines which io port pins are connected to the various
44 * signals required to program a Xilinx fpga.
46 * A ram/flash "bank" refers to memory controlled by the same chip select.
48 * the eeprom contents are defined as in technical note #2 - basically,
49 * a header, zero or more records in no particular order, and a 32 bit crc
50 * a record is 1 or more type bytes, a length byte and "length" bytes.
