platform/x86: mlx-platform: Modify DMI matching order
Modify DMI matching order: perform matching based on DMI_BOARD_NAME before matching based on DMI_BOARD_VENDOR and DMI_PRODUCT_NAME in order to reduce the number of ‘dmi_table’ entries necessary for new systems support and keep matching order in logical way. For example, the existing check for DMI_PRODUCT_NAME with prefixes “MSN27", “MSN24”, "MSB” matches systems MSN2700-BXXXX, MSN2700-XXXX, MSN2410-BXXXX, MSB7800-XXXX, where ‘XXXX’ specifies some systems hardware flavors. At the same time these systems also matched by DMI_BOARD_NAME “VMOD0001”, because they all have the same platform configuration (LED, interrupt control, mux etcetera). New systems with different platform configuration, but with similar DMI_PRODUCT_NAME MSN2700-2XXXX, MSN2700-2XXXX, MSB7800-2XXXX are about to be added. These system have similar DMI_PRODUCT_NAME, since they have same ports configuration as their predecessors. All new systems will be matched by DMI_BOARD_NAME “VMOD0008”. With the change provided in the patch it is enough just to add “VMOD0008” match following natural after “VMOD0007”, otherwise “VMOD0008” or all “MSN2700-2XXXX”, “MSN2700-2XXXX”, “MSB7800-2XXXX” should be added on top of ‘mlxplat_dmi_table” in order to be matched before “MSN27", “MSN24”, "MSB”.
