6.2.1.2
SPI Register Decoding
All SPI accesses from the IPMC towards the FPGA with the SPI select signal BMC_SPI_S0_N
asserted are for the internal registers.
6.2.2
POST Code Register
The FPGA provides and 8-bit wide register to store POST codes to the LPC I/O address 0x80.
The IPMC may read the POST code using the SPI interface (with the signal BMC_SPI_S0_N
asserted) and the SPI address 0x7F.
