Subject: [PATCH] ArmPlatformPkg: PrePeiCore: write early hello message to the
|
||
|
|
serial port (RH)
|
||
|
|
|
||
|
|
The FixedPcdGetSize() macro expands to an integer constant, therefore an
|
||
|
|
optimizing compiler can eliminate the new code, if the platform DSC
|
||
|
|
doesn't override the empty string (size=1) default of
|
||
|
|
PcdEarlyHelloMessage.
