SecurityPkg/SecurityPkg.dec: Move PcdCpuRngSupportedAlgorithm to MdePkg
|
||
|
|
|
||
|
|
In order to use PcdCpuRngSupportedAlgorithm in the MdePkg in a
|
||
|
|
following patch and to avoid making the MdePkg dependent on another
|
||
|
|
package, move PcdCpuRngSupportedAlgorithm to the MdePkg.
|
||
|
|
|
||
|
|
As the Pcd is only used for AARCH64, place it in an AARCH64
|
||
|
|
specific sections.
