[edk2-devel] [PATCH] BaseTools/LzmaCompress: Fix the option "d" dictionary size

Posted by Zhang, Shenglei 2 weeks ago
The range of dictionary size is set from [0,30] to [0,27].
And update the help information for this.
The previous logic for processing the parameter dict size is incorrect.
Now fix the logic.
The option "d" is added at 6b80310f34199d1f62e45e40fa902734735091fa.
