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