[PATCH v1 0/2] soc: add NPCM LPC BPC driver support

[Tomer Maimon <tmaimon77@gmail.com>]

This patch set adds LPC BIOS Post code (BPC) support for the
Nuvoton NPCM Baseboard Management Controller (BMC).

Nuvoton BMC NPCM LPC 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.

The NPCM7xx BPC driver tested on NPCM750 evaluation board.

NPCM BPC driver upstream process start few months ago on misc folder
http://lkml.iu.edu/hypermail/linux/kernel/1904.2/00412.html

The NPCM LPC BPC is similar to Aspeed LPC snoop, last 
kernel 5.0.2 Aspeed LPC snoop driver moved from misc folder to 
soc folder, so it seems NPCM BPC dirver should upstream to soc 
as well.

I have created common lpc-snoop documentation for both 
Nuvoton and Aspeed drivers as Andrew suggested.

I add Andrew and Rob reviewed signature because they already reviewed 
and signed  the lpc-snoop documentation in the misc folder
