ArmPlatformPkg: PL011 Dynamic clock freq Support Some platform support dynamic clocking, which is controlled by some jumper setting or hardware registers. Result of that is that PCD PL011UartClkInHz would need to be updated for frequency change. This patch implements support for dynamic frequency for PL011 uart. This patch implements default lib, which is using Pcd. Platform which needs dynamic clocking needs implement PL011UartClockLib Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Udit Kumar <udit.kumar@nxp.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>

ArmPlatformPkg: Fix Ecc error 8001 This patch fixes the following Ecc reported error: File header doesn't exist File header comment missing the ""Copyright"" Even though a copyright is present in the header file, the leading '*' char prevents the Ecc tool from detecting it. According to the edk2 coding specifcation, section 5.2.3 "File Heading", there should not be leading '*' char.
