* ARM: i.MX6: TQMa6ulx: add OP-TEE supportSascha Hauer2024-03-132-0/+6
| | | | | | | | | | | This adds OP-TEE support for the TQMa6ulx board. The OP-TEE binary is loaded from PBL. Later on in barebox proper the OP-TEE provided overlay node is applied to the barebox live tree for barebox to probe OP-TEE and also to reserve the memory used by OP-TEE. The overlay is also registered as a fixup to be applied on the Linux device tree.

| * | ARM: i.MX93: Add OP-TEE supportSascha Hauer2024-01-222-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables OP-TEE support for i.MX93. This is done in a way very similar to how it's done on i.MX8M. One major difference is that the i.MX93 needs a RAM firmware for the EdgeLock secure enclave. Without it OP-TEE doesn't work properly. The firmware can be integrated into the i.MX93 image where the ROM picks it up automatically. The firmware image is SoC revision specific though, so we load the firmware during runtime to avoid having to create a barebox image for each SoC revision.

* | firmware: fix missing firmware handling for external firmwareMarco Felsch2024-01-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we depend on the external firmware file since we need it for the sha256sum. But this dependency break the 'optional missing firmware' feature. Fix this by dropping the firmware file prerequisite and instead evaluate the FWNAME_EXISTS variable. If the firmware file does not exist a dummy file is created and the build continues till the linking process (like we do for the other firmware).

|/ | | | | | | | | | | | | | | | | | | | A pbl is not rebuilt when the firmware file specified in fw-external-y changes. $(patsubst %.gen.o,$(obj)/%.extgen.pbl.o, $(pbl-y)) is executed before pbl-y actually contains the contents of fw-external-y. Also we want to do the subsitution only for the external firmware files, not for pbl-y. To fix this use a intermediate variable pbl-fwext-y instead of pbl-y and initialize it before usage. Also, use $$(wildcard $(fwdir)/%) instead of $(fwdir)/% to successfully compile when the external firmware file is missing.

* firmware: fix dependency tracking for PBL firmware filesAhmad Fatoum2023-09-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | $(wildcard $(fwdir)/%) was added to allow for optional firmware, but in return it broke dependency tracking, because it was evaluated before the static pattern rule it's a part of. Fix the dependency tracking by only evaluating it in a secondary expansion. That this works as expected can be verified with: make -p | grep 'imx8mn-bl31.bin.gen.pbl.o:.*imx8mn-bl31.bin ' Which will return no result before this patch, but with it applied, it will correctly show the dependency.

| | | | | | | | | | | | | | | | | | | We want to print `\n' literally into the *.gen.S file, so gas turns it into a literal new line character.

* firmware: don't hardcode firmware paths in srctree for existence checkAhmad Fatoum2023-06-281-39/+0
| | | | | | | | | | | | | | | | | | | Now that PBL firmware can be made optional, we can drop the existence checks in the Kconfig. These were flawed anyway, because they didn't take CONFIG_EXTRA_FIRMWARE_DIR into account and they led to issues with build system recipes that didn't expect firmware to be required before compilation step at oldconfig/menuconfig time.

In any case, barebox images which contain firmware in their PBL that's not available will be marked specially to reduce the risk of accidentally putting them to use: * They're truncated to zero size * The final "images built:" section marks them as having firmware missing * They are omitted from the listing in the barebox-flash-images file * Each barebox-broken.img is accompanied with a barebox-broken.img.missing-firmware containing a newline delimited list of missing firmware images Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20230627055239.3908872-5-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* firmware: turn missing firmware into linker errorAhmad Fatoum2023-06-281-1/+6
| | | | | | | | | | | | | | | | Appending to firmware-y results in an assembly file being generated that defines a section embedding the firmware in question verbatim via .incbin. To update the assembly file as required, the target has a dependency on the firmware. When the firmware is missing, the build will abort there. In preparation for deferring missing PBL firmware errors till the very end, let's remove the firmware dependency if the missing firmware file is built into PBL and replace the .incbin with a reference to an ultimately undefined variable.

This commit replaced the usage of $(fw-external-y) by $(obj-pbl-y) and added the '.gen.o' suffix directly but didn't adapted the patsubst logic for tracking the binary firmware files. As result a firmware binary file update is not recognized by make and and won't make into the final binary.

* firmware: add external firmware PBL supportAhmad Fatoum2022-08-221-4/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, barebox embds firmware into the binary referencing it, which means that device tree blobs, RAM training code and e.g. TF-A for i.MX8M end up in the prebootloader, while, e.g. Freescale FMan microcode ends up in barebox proper. The only exception so far was barebox proper: When only the PBL fits in on-chip SRAM, barebox proper is chainloaded from the boot medium. To avoid TOCTOU attack, it's read fully into DRAM after setup and then a SHA256 is calculated and compared against the hash embedded in barebox PBL, which in a secure boot system would be trusted by virtue of the PBL as a whole being verified beforehand by the BootROM. Reuse this mechanism to support arbitrary firmware, which is now termed external firmware. Such firmware is placed beyond the piggydata (barebox proper) and only offset and hash are included in the prebootloader image. The new get_builtin_firmware_ext() is used to retrieve this external firmware after integrity verification with SHA256. This enables referencing firmware blobs from PBL that would bloat the size of the PBL beyond what can fit into on-chip SRAM, e.g. very big OP-TEE binaries. As users of get_builtin_firmware() didn't have to worry about TOCTOU so far, we panic when a firmware verification fails to ensure that we never load an OP-TEE that has been modified in-transit We can't include the OP-TEE binary in barebox proper, because we need to install it in EL3, but barebox proper on the i.MX8M runs as BL33 in a lower exception level.

The dependency from the pbl-*.gen.o to the firmware files are missing, add them. Reported-by: Rouven Czerwinski <r.czerwinski@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ARM: i.MX8M: Add TF-A loading support for i.MX8MMSascha Hauer2020-02-192-0/+4
|/ | | | | | | Basically the same as for i.MX8MQ, just some function split up needed to account for different base addresses for the TF-A on both SoCs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * firmware: add gitignore file for *.binRouven Czerwinski2019-06-071-0/+1
| | | | | | | | | | | | | | | | There is no intention to commit static firmware to this directory. If there is a use case, gitignore can be overridden explicitly. Signed-off-by: Rouven Czerwinski <r.czerwinski@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ARM: Layerscape: Add PPA firmware supportSascha Hauer2019-05-131-0/+2
|/ | | | | | | | | | | The "Primary Protected Application" (PPA) is a PSCI compliant firmware distributed by NXP. It is needed to start the secondary cores on Layerscape SoCs. Without it Linux will be started in EL3 and doesn't work properly. The precompiled firmware images can be found on https://github.com/NXP/qoriq-ppa-binary and are not included in barebox.

* net: Add Freescale FMan ethernet supportSascha Hauer2019-03-131-0/+2
| | | | | | | | | | | | | | | | | | | This adds ethernet support for the Freecale Layerscape SoCs. The architecture in these SoCs is called "Data Path Acceleration Architecture" (DPAA). It is comprised of: - The Queue Manager (QMan) - Buffer Manager (BMan) - Frame Manager (FMan) - Multirate Ethernet Media Access Controller (mEMAC) The code is based on the corresponding U-Boot driver enriched with device tree parsing and proper device driver support. Tested on LS1046a, should work on other SoCs aswell with some minor quirks. SerDes support has been removed for now. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* firmware: drop the imx subdirLucas Stach2019-02-011-5/+5
| | | | | | | | | | We don't intend to ship any files in this directory, so there is no risk of the directory getting too crowded over time. Drop the subdir as this makes it easier for a outer build system to drop all the needed firmwares into the correct directory.

* firmware: add a note about license implicationsLucas Stach2019-02-011-0/+7
| | | | | | | | | Building additional firmware into the boot image has some license implications, which should be considered by the user, so add a short note about this. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* firmware: imx: remove prebuilt ATF binaryLucas Stach2019-02-011-0/+0
| | | | | | | | | | | | | | | | | | | | The prebuilt ATF binary is in fact a license compliance issue. While the used BSD-3-clause license allows aggregation with the Barebox binary, the chosen license requires us to ship the license text itself for the source distribution and also for the binary form if the built boot image contains the ATF binary. As this is a restriction that only applies to some boot images, depending on the Barebox configuration, it's non-trivial to do proper license compliance from within the Barebox source. Remove the prebuilt binary and rely on the external build system or user to provide the correct binary. Most system build systems already provide a proper way to handle the license dependency issue.
