The difference between SM8550 and QCS8550 is QCS8550 doesn't have modem RF system. QCS8550 is mainly used in IoT products. QCS8550 firmware has different memory map compared to SM8550. The memory map will be runtime added through bootloader. There are 3 types of reserved memory regions here: 1. Firmware related regions which aren't shared with kernel. The device tree source in kernel doesn't need to have node to indicate the firmware related reserved information. Bootloader converys the information by updating devicetree at runtime. This will be described as: UEFI saves the physical address of the UEFI System Table to dts file's chosen node. Kernel read this table and add reserved memory regions to efi config table. Current reserved memory region may have reserved region which was not yet used, release note of the firmware have such kind of information. 2. Firmware related memory regions which are shared with Kernel The device tree source in the kernel needs to include nodes that indicate fimware-related shared information. A label name is suggested because this type of shared information needs to be referenced by specific drivers for handling purposes. 3. Remoteproc regions. Remoteproc regions will be reserved and then assigned to subsystem firmware later. Here is a reserved memory map for this platform: 0x100000000 +-------------------+ | | | Firmware Related | | | 0xd4d00000 +-------------------+ | | | Kernel Available | | | 0xa7000000 +-------------------+ | | | Remoteproc Region | | | 0x8a800000 +-------------------+ | | | Firmware Related | | | 0x80000000 +-------------------+ Reviewed-by: Dmitry Baryshkov Signed-off-by: Tengfei Fan --- arch/arm64/boot/dts/qcom/qcs8550.dtsi | 167 ++++++++++++++++++++++++++ 1 file changed, 167 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/qcs8550.dtsi diff --git a/arch/arm64/boot/dts/qcom/qcs8550.dtsi b/arch/arm64/boot/dts/qcom/qcs8550.dtsi new file mode 100644 index 000000000000..685668c6ad14 --- /dev/null +++ b/arch/arm64/boot/dts/qcom/qcs8550.dtsi @@ -0,0 +1,167 @@ +// SPDX-License-Identifier: BSD-3-Clause +/* + * Copyright (c) 2023-2024, Qualcomm Innovation Center, Inc.
