2025-03-30spl: return header size to spl_load in os bootAnshul Dalal
During linux build process the header size is computed including the BSS whereas it's removed when creating the uncompressed image. Therefore the size of the uncompressed image on filesystem will be smaller than the size specified in the header. This causes issues when loading the kernel image from the SPL (as in falcon boot) with spl_load since it compares the read file size from the FS to the header size form the image. Which leads to the following check in `include/spl_load.h` failing to -EIO when loading kernel image: return read < spl_image->size ? -EIO : 0; Therefore we should return the header size back to spl_load instead of the file size in falcon boot when not loading a FIT image.

2025-02-14Merge patch series "Introduce K3 remoteproc driver for M4 subsystem"Tom Rini
Judith Mendez <[email protected]> says: Some K3 devices like am62x and am64x have a M4 processor in the MCU voltage domain. This patch series introduces remoteproc M4 driver which will be used to load firmware into and start the M4 remote core. This series also adds support for R5F cores on am64x SoCs in patch 2 and sets up environment to load FW in remote cores in patch 3,4,5. This patch series also enables remoteproc drivers by default as per what remoteproc sybsystem is supported per SoC, thus all remoteproc options are now deleted in configs/* since they are no longer required. This patch series was tested on am64x EVM, am62x SK, am62ax SK, am62px SK boards. Any additional tested by's are welcome since I was not able to test any additional boards.

2025-01-22Merge patch series "vbe: Series part F"Tom Rini
Simon Glass <[email protected]> says: This includes various patches towards implementing the VBE abrec bootmeth in U-Boot. It mostly focuses on introducing a relocating SPL-loader so that VBE can run in the limited amount of SRAM available on many devices. Another minor new feature is support in VBE for specifying the image phase when loading from a FIT. This allows a single FIT to include images for several boot phases, thus simplifying image-creation. One lingering niggle in this series is that it has a different code path for sandbox, since it does not support the relocating jump. It should be possible to resolve this with additional work, but I have not attempted this so far. For v2, I have split the first patch into 5 pieces, to make it easier to see the code-size impact, plus added a few tweaks to reduce code size. Again, only MMC is supported so far. Looking ahead, series G will have some more plumbing and H some rk3399 pieces. That should be enough to complete these feature. Here is a run in my lab, with the VBE ABrec bootmeth. You can see that VPL runs before memory is set up.

2025-01-22spl: Plumb in the relocating loaderSimon Glass
This is fairly easy to use. The SPL loader sets up some fields in the spl_image_info struct and calls spl_reloc_prepare(). When SPL is ready to do the jump it must call spl_reloc_jump() instead of jump_to_image(). Add this logic. Signed-off-by: Simon Glass <[email protected]>
2025-01-22spl: Add support for a relocating jump to the next phaseSimon Glass
When one xPL phase wants to jump to the next, the next phase must be loaded into its required address. This means that the TEXT_BASE for the two phases must be different and there cannot be any memory overlap between the code used by the two phases. It also can mean that phases need to be moved around to accommodate any size growth. Having two xPL phases in SRAM at the same time can be tricky if SRAM is limited, which it often is. It would be better if the second phase could be loaded somewhere else, then decompressed into place over the top of the first phase. Introduce a relocating jump for xPL to support this. This selects a suitable place to load the (typically compressed) next phase, copies some decompression code out of the first phase, then jumps to this code to decompress and start the next phase. This feature makes it much easier to support Verified Boot for Embedded (VBE) on RK3399 boards, which have 192KB of SRAM. Signed-off-by: Simon Glass <[email protected]>

2025-01-14common: Move autoprobe out to board initSimon Glass
Rather than doing autoprobe within the driver model code, move it out to the board-init code. This makes it clear that it is a separate step from binding devices. For now this is always done twice, before and after relocation, but we should discuss whether it might be possible to drop the post-relocation probe. For boards with SPL, the autoprobe is still done there as well. Note that with this change, autoprobe happens after the EVT_DM_POST_INIT_R/F events are sent, rather than before.

2024-10-16net: introduce alternative implementation as net/lwip/Jerome Forissier
Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by adding a new net/lwip/ directory and the NET_LWIP symbol. Network support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent commits will introduce the lwIP code, re-work the NETDEVICE integration and port some of the NET commands and features to lwIP. SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols that are part of NET (such as arp_init(), arp_timeout_check(), arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be added later. Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP because of dependencies on net_loop(), tftp_timeout_ms, tftp_timeout_count_max and other NET things. Let's add a dependency on !NET_LWIP for now. SANDBOX can select NET_LWIP but doing so will currently disable the eth dm tests as well as the wget tests which have strong dependencies on the NET code. Other adjustments to Kconfig files are made to fix "unmet direct dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when the default networking stack is set to NET_LWIP ("default NET_LWIP" instead of "default NET" in Kconfig). The networking stack is now a choice between NO_NET, NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be 'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.

2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <[email protected]> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.
