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