[PATCH v2 20/25] binman: Support splitting an ELF file into multiple nodes
Simon Glass
sjg at chromium.org
Thu Feb 24 00:00:35 CET 2022
Some boards need to load an ELF file using the 'loadables' property, but
the file has segments at different memory addresses. This means that it
cannot be supplied as a flat binary.
Allow generating a separate node in the FIT for each segment in the ELF,
with a different load address for each.
Also add checks that the fit,xxx directives are valid.
Signed-off-by: Simon Glass <sjg at chromium.org>
---
Changes in v2:
- Rewrite this to use the new FIT entry-type implementation
- Rename op-tee to tee-os

+ Split an ELF file into a separate node for each segment. This uses the

+
+ fit,load
+ Generates a `load = <...>` property with the load address of the

+ Generates a `entry = <...>` property with the entry address of the

+ Generates a `data = <...>` property with the contents of the segment
+
+ fit,loadables
+ Generates a `loadable = <...>` property with a list of the generated
+ nodes (including all nodes if this operation is used multiple times)
+
+
+Here is an example showing ATF, TEE and a device tree all combined::
+
+ fit {
+ description = "test-desc";
+ #address-cells = <1>;
+ fit,fdt-list = "of-list";
+
+ images {
+ u-boot {
+ description = "U-Boot (64-bit)";
+ type = "standalone";
+ os = "U-Boot";

+ @config-SEQ {
+ description = "conf-NAME.dtb";
+ fdt = "fdt-SEQ";
+ firmware = "u-boot";
+ fit,loadables;
+ };
+ };
+ };
+
+If ATF-BL31 is available, this generates a node for each segment in the
+ELF file, for example::
+
+ images {
+ atf-1 {
+ data = <...contents of first segment...>;
+ data-offset = <0x00000000>;
+ entry = <0x00040000>;
+ load = <0x00040000>;

+ os = "arm-trusted-firmware";
+ arch = "arm64";

+ description = "ARM Trusted Firmware";
+ };

+ data = <...contents of second segment...>;
+ load = <0xff3b0000>;
+ compression = "none";
+ os = "arm-trusted-firmware";
+ arch = "arm64";
+ type = "firmware";
+ description = "ARM Trusted Firmware";
+ };
+ };
+
+The same applies for OP-TEE if that is available.
+
+If each binary is not available, the relevant template node (@atf-SEQ or
+ at tee-SEQ) is removed from the output.
+
+This also generates a `config-xxx` node for each device tree in `of-list`.
+Note that the U-Boot build system uses `-a of-list=$(CONFIG_OF_LIST)`
+so you can use `CONFIG_OF_LIST` to define that list. In this example it is
+set up for `firefly-rk3399` with a single device tree and the default set
+with `-a default-dt=$(CONFIG_DEFAULT_DEVICE_TREE)`, so the resulting output
+is::
+
+ configurations {
+ default = "config-1";
+ config-1 {
+ loadables = "atf-1", "atf-2", "atf-3", "tee-1", "tee-2";
+ description = "rk3399-firefly.dtb";
+ fdt = "fdt-1";
+ firmware = "u-boot";
+ };
+ };
+
+U-Boot SPL can then load the firmware (U-Boot proper) and all the loadables
+(ATF and TEE), then proceed with the boot.
