[edk2-devel] [PATCH] CryptoPkg/BaseCryptLib: remove unused code for IPF
Posted by Wang, Jian J 4 years, 11 months ago 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1805

CryptRandItc.c is only for IPF arch, which has not been supported any
more in edk2. And no module actually reference this file. This patch
just removes it from tree.

I see no module consumes this source file. 

The change is good. Reviewed-by: Liming Gao <liming.gao@intel.com>
