From ee8274d8015148cb6e4dd836df107466635eeaa2 Mon Sep 17 00:00:00 2001 From: Stanimir Varbanov Date: Mon, 24 Feb 2025 10:35:58 +0200 Subject: [PATCH] PCI: brcmstb: Expand inbound window size up to 64GB MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit 25a98c727015638baffcfa236e3f37b70cedcf87 ] The BCM2712 memory map can support up to 64GB of system memory, thus expand the inbound window size in calculation helper function. The change is safe for the currently supported SoCs that have smaller inbound window sizes. Signed-off-by: Stanimir Varbanov Reviewed-by: Florian Fainelli Reviewed-by: Jim Quinlan Tested-by: Ivan T.
