firmware: Remove FW_PAYLOAD_FDT_PATH compile-time option

2020-10-18T04:59:59Z

The FW_PAYLOAD_FDT_PATH compile-time option is replaced by FW_FDT_PATH compile-time option which is more flexible and common across all OpenSBI firmwares. This patch removes FW_PAYLOAD_FDT_PATH and updates related documentation to use FW_FDT_PATH. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

firmware: Add common FW_FDT_PATH compile-time option

2020-10-18T04:58:26Z

Currently, only FW_PAYLOAD has mechanism to embed external FDT using FW_PAYLOAD_FDT_PATH compile-time option. This patch adds a common FW_FDT_PATH compile-time option to embed external FDT for all OpenSBI firmwares (i.e FW_JUMP, FW_PAYLOAD, and FW_DYNAMIC). Signed-off-by: Anup Patel Reviewed-by: Atish Patra

firmware: Remove FW_PAYLOAD_FDT and related documentation

2020-06-05T03:33:05Z

Now that no platform is using FW_PAYLOAD_FDT mechanism, we remove related code from Makefile and related documentation. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

firmware: Add fw_dynamic firmware

2019-05-10T06:56:22Z

This patch provides first-cut implementation of fw_dynamic firmware. As compared to fw_jump and fw_payload, the fw_dynamic obtains next address, next mode and OpenSBI options from struct fw_dynamic_info. The previous booting stage can create struct fw_dynamic_info in memory and pass address of struct fw_dynamic_info in 'a2' register. Also, the struct fw_dynamic_info has versioning as well so changes to the struct fw_dynamic_info can be done in a backward compatible manner. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

TOP: Allow building platform out-of-tree

2019-04-09T03:44:09Z

This patch extends our current build-system for building platform sources which are not part of OpenSBI sources. For example: Let's say we have out-of-tree ABC platform sources. We place these sources under /ABC directory along with its config.mk and objects.mk. To build out-of-tree ABC platform from OpenSBI directory: $ make PLATFORM_DIR=/ABC OR $ make PLATFORM_DIR= PLATFORM=ABC To build out-of-tree ABC platform from /ABC directory: $ make PLATFORM_DIR=/ABC -C OR $ make PLATFORM_DIR= PLATFORM=ABC -C Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

Makefile: Add support for device tree compilation

2019-01-21T04:28:33Z

Add rules to compile dts files into dtb files using the device tree compiler (dtc). A platform can specify the DTS file to compile using the platform-dtb-y variable. The flattened device tree binary file to be used for building the final polatform firmware can be specified using the new FW_PAYLOAD_FDT firmware configuration option to point to the automatically compiled FDT file. Using the existing FW_PAYLOAD_FDT_PATH configuration option is still possible and will take precedence over the FW_PAYLOAD_FDT definition. Signed-off-by: Damien Le Moal
