2024-02-29Merge patch series "Handoff bloblist from previous boot stage"Tom Rini
Raymond Mao <raymond.mao@linaro.org> says: This patch set adds/adapts a few bloblist APIs and implements Arm arch custom function to retrieve the bloblist (aka. Transfer List) from previous loader via boot arguments when BLOBLIST option is enabled and all boot arguments are compliant to the register conventions defined in the Firmware Handoff spec v0.9. If an arch wishes to have different behaviors for loading bloblist from the previous boot stage, it is required to implement the custom function xferlist_from_boot_arg().
2024-02-29dts: OF_HAS_PRIOR_STAGE should depend on !BLOBLISTRaymond Mao
When BLOBLIST is enabled, FDT is expected to be from bloblist carried from previous stage, instead of from OF_BOARD, therefore only enable OF_HAS_PRIOR_STAGE when BLOBLIST is disabled. Signed-off-by: Raymond Mao <raymond.mao@linaro.org>
2024-02-29bloblist: Load the bloblist from the previous loaderRaymond Mao
During bloblist initialization, load the bloblist via boot arguments from the previous loader. If a valid bloblist exists in boot arguments, relocate it into the fixed bloblist memory region. If not, fallback to support BLOBLIST_ADDR or BLOBLIST_ALLOC. Signed-off-by: Raymond Mao <raymond.mao@linaro.org>

2024-02-29bloblist: refactor of bloblist_reloc()Raymond Mao
The current bloblist pointer and size can be retrieved from global data, so we don't need to pass them from the function arguments. This change also help to remove all external access of gd->bloblist outside of bloblist module.

2024-02-29bloblist: check bloblist with specified buffer sizeRaymond Mao
Instead of expecting the bloblist total size to be the same as the pre-allocated buffer size, practically we are more interested in whether the pre-allocated buffer size is bigger than the bloblist total size.

2024-02-29bloblist: add API to check the register conventionsRaymond Mao

2024-02-28Merge patch series "mux: Drop usage of "u-boot,mux-autoprobe""Tom Rini
Roger Quadros <rogerq@kernel.org> says: MUX driver should autoprobe if the device tree has "idle-states" property. Drop using the custom "u-boot,mux-autoprobe" property in TI device trees.

2024-02-28mux: autoprobe if "idle-states" present in device treeRoger Quadros
Some platforms need the MUX state to be auto initialized at boot time even if there are no explicit users for the MUX. In these cases, the MUX device tree has "idle-states" property which specifies what state the MUX should be initialized to. So far we were relying on custom u-boot property "u-boot,mux-autoprobe" to autoprobe such MUXes. This patch causes the MUX to autoprobe if it has "idle-states" property in device tree. This should allow us to stop using the custom "u-boot,mux-autoprobe" property. Signed-off-by: Roger Quadros <rogerq@kernel.org>

2024-02-28arm: separate .data and .text sections of EFI binariesHeinrich Schuchardt
EFI binaries should not contain sections that are both writable and executable. Separate the RX .text section from the RW .data section. We currently don't created relocation sections (.rel.*) for our EFI binaries. Anyway these would have to be converted to PE/COFF relocations. Enumerate them under DISCARD and add a comment. Correct the characteristics of the sections. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com> Acked-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>

2024-02-28efi_loader: set IMAGE_DLLCHARACTERISTICS_NX_COMPATHeinrich Schuchardt
The IMAGE_DLLCHARACTERISTICS_NX_COMPAT flag marks an EFI binary where the following conditions are met [1]: * Executable and writable sections are separated. * The application does not run self-modifying code. * The application uses the EFI_MEMORY_ATTRIBUTE_PROTOCOL when loading executable code. * The application does not assume that all memory ranges are usable. * The stack is not expected to be executable. The only EFI binaries U-Boot provides that do not fulfill these requirements are the EFI app and the EFI payload. Once we have implemented separation of writable and executable memory in U-Boot we can use the IMAGE_DLLCHARACTERISTICS_NX_COMPAT flag to decide if we will load an EFI binary.

2024-02-27Merge patch series "kbuild: Allow for CONFIG_SYS_CONFIG_NAME to be unset"Tom Rini
Perform a little re-organization of Kconfig so that we can have CONFIG_SYS_CONFIG_NAME be unset and so not require a "board.h" file. Then go and remove a number of now not required header files.
2024-02-27Kconfig: Centralize prompting for SYS_CONFIG_NAMETom Rini
Generally speaking, we do not prompt for this value and define it in the board specific Kconfig file. There are some valid use cases however today where we do prompt for this value, so instead of having this be done in a number of locations, do this at the top-level location only. This removes the question from a number of other locations and makes it consistent that when we do set the value directly, we always do it the same way. We don't need to specify the type, it's always string. Signed-off-by: Tom Rini <trini@konsulko.com>
