| 3 | # This script is used for generating callout lists from the MRW for devices |
| 4 | # that can be accessed from the BMC. The callouts have a location code, the |
| 5 | # target name (for debug), a priority, and in some cases a MRU. The script |
| 6 | # supports I2C, FSI, SPI, FSI-I2C, and FSI-SPI devices. The output is a JSON |
| 7 | # file organized into sections for each callout type, with keys based on the |
| 8 | # type. I2c uses a bus and address, FSI uses a link, and SPI uses a bus |
| 9 | # number. If FSI is combined with I2C or SPI, then the link plus the I2C/SPI |
| 10 | # keys is used. Multi-hop FSI links are indicated by a dash in between the |
| 11 | # links, eg "0-1". |
| 12 | # |
| 13 | # An example section is: |
| 14 | # "FSI": |
| 15 | # { |
| 16 | # "5": |
| 17 | # { |
| 18 | # "Callouts":[ |
