Intel BMC 에서 MCTP over PCIe VDM 통신 경로 분석

• Intel BMC GitHub : https://github.com/orgs/Intel-BMC/repositories?type=all
• libmctp
• astpcie.h 에서 선언된 참조 device file
• /* driver device file */
  #define AST_DRV_FILE "/dev/aspeed-mctp"
• https://github.com/Intel-BMC/libmctp/blob/master/astpcie.h
• astpcie.c 
• 위 file 을 open 하여 ioctl(), write, read 하여 통신.
  
• https://github.com/Intel-BMC/libmctp/blob/master/astpcie.c
• kernel 의 aspeed-mctp device driver
• drivers/soc/aspeed/aspeed-mctp.c
• AST2600 의 MCTP controller HW 에 access 하여 PCIe VDM MCTP 통신 수행
• https://github.com/Intel-BMC/linux/blob/dev-5.15-intel/drivers/soc/aspeed/aspeed-mctp.c
• AST2600 datasheet 에서 내용 확인 필요.
