If anyone has any objections, please let me know. ------------------ [ Upstream commit bb4add2ce991e4ec891b5a0287fd1ab77b631979 ] This patch adds new ports-implemented mask, which is required to get achi working on the mainline. Without this patch value read from PORTS_IMPL register which is zero would not enable any ports for software to use.
