2025-03-26blkmap: pass information on ISO image to the OSSughosh Ganu
The EFI HTTP boot puts the ISO installer image at some location in memory. Information about this image has to be passed on to the OS kernel, which is done by adding a persistent memory(pmem) node to the devicetree(DT) that is passed to the OS. The OS kernel then gets information about the presence of this ISO image and proceeds with the installation. In U-Boot, this ISO image gets mounted as a memory mapped blkmap device slice, with the 'preserve' attribute. Add a helper function which iterates through all such slices, and invokes a callback. The callback adds the pmem node to the DT and removes the corresponding memory region from the EFI memory map. Invoke this helper function as part of the DT fixup which happens before booting the OS.

2025-03-26blkmap: add an attribute to preserve the mem mappingSughosh Ganu
Some blkmap memory mapped devices might have to be relevant even after U-Boot passes control to the next image as part of the platform boot. An example of such a mapping would be an OS installer ISO image, information for which has to be provided to the OS kernel. Use the 'preserve' attribute for such mappings. The code for adding a pmem node to the device-tree then checks if this attribute is set, and adds a node only for mappings which have this attribute.

2025-03-26blkmap: store type of blkmap slice in corresponding structureSughosh Ganu
Add information about the type of blkmap slices as an attribute in the corresponding slice structure. Put information in the blkmap slice structure to identify if it is associated with a memory or linear mapped device. Which can then be used to take specific action based on the type of the blkmap slice.

2025-01-20blk: Make block subsystems select BLKTom Rini
The BLK symbol has a few meanings, one of which is that it controls the driver model portion of a "block device". Rather than having this hidden symbol be "default y if ..." it should be select'd by the various block subsystems. Symbols such as PVBLOCK which already select'd BLK are unchanged".

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.

2024-08-09sandbox: Return error code from read/write/seekSimon Glass
The existing API for these functions is different from the rest of U-Boot, in that any error code must be obtained from the errno variable on failure. This variable is part of the C library, so accessing it outside of the special 'sandbox' shim-functions is not ideal. Adjust the API to return an error code, to avoid this.

2024-08-08drivers: introduce UBI block abstractionAlexey Romanov
UBI block is an virtual device, that runs on top of the MTD layer. The blocks are UBI volumes. Intended to be used in combination with other MTD drivers. Despite the fact that it, like mtdblock abstraction, it used with UCLASS_MTD, they can be used together on the system without conflicting. For example, using bcb command: # Trying to load bcb via mtdblock: $ bcb load mtd 0 mtd_partition_name # Trying to load bcb via UBI block: $ bcb load ubi 1 ubi_volume_name User always must attach UBI layer (for example, using ubi_part()) before using UBI block device.
