| 4 | Subject: [PATCH] Change UID of variable index in SMM |
| 5 | |
| 6 | This patch fixes the os_indications setVariable() failure. The variable |
| 7 | index UID in SMM gateway which was 1 is changed in this patch. TFM has a |
| 8 | special usage for variable with UID 1, which makes it write once only. |
| 9 | This is not required for SMM variable index. |
