This patch set adds BIOS Post code (BPC) support for the Nuvoton NPCM Baseboard Management Controller (BMC). Nuvoton BMC NPCM BIOS Post Code (BPC) monitoring two configurable I/O addresses written by the host on the Low Pin Count (LPC) bus, the capture data stored in 128-word FIFO. NPCM BPC can support capture double words. I have created common lpc-snoop documentation for both Nuvoton and Aspeed drivers as Andrew suggested. Andrew Jeffery: https://patchwork.kernel.org/patch/10506269/ I prefer to add the lpc-dnoop documentation to misc folder instead of creating new /devicetree/binding folder that named BMC as been done in the last lpc-snoop patchset because I am not sure is something that should be done for only one module for now. https://patchwork.kernel.org/patch/10506269/ The NPCM7xx BPC driver tested on NPCM750 evaluation board.
