The differnece between SM8550 and QCS8550 is QCS8550 doesn't have modem RF system. QCS8550 is mainly used in IoT scenarios. QCS8550 firmware has different memory map with SM8550 firmware. 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. OS bootloader conveys the information by update device tree in 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 Each region has a specific node with specific label name for later phandle reference from other driver dt node. 3. PIL regions. PIL 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 +------------------+ | | | PIL Region | | | 0x8a800000 +------------------+ | | | Firmware Related | | | 0x80000000 +------------------+ Note that: 0xa7000000..0xA8000000 is used by bootloader, when kernel boot up, it is available for kernel usage. This region is not suggested to be used by kernel features like ramoops, suspend resume etc. Signed-off-by: Tengfei Fan --- arch/arm64/boot/dts/qcom/qcs8550.dtsi | 169 ++++++++++++++++++++++++++ 1 file changed, 169 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..a3ebf3d4e16d --- /dev/null +++ b/arch/arm64/boot/dts/qcom/qcs8550.dtsi @@ -0,0 +1,169 @@ +// SPDX-License-Identifier: BSD-3-Clause +/* + * Copyright (c) 2023-2024, Qualcomm Innovation Center, Inc.
