| 4 | Subject: [PATCH] Increase SMM gateway UEFI variable macro value |
| 5 | |
| 6 | The maximum number of UEFI variables that be supported by SMM |
| 7 | gateway is currently 40. When more than 40 variables are written, |
| 8 | or read SMM gateway returns error code. Currently this value is |
| 9 | increased to 100 to support more UEFI variables. |
