2022-07-06common: spl: spl_spi: add support for dynamic override of sf busVaishnav Achath
Currently the SPI flash to load from is defined through the compile time config CONFIG_SF_DEFAULT_BUS and CONFIG_SF_DEFAULT_CS, this prevents the loading of binaries from different SPI flash using the same build.E.g. supporting QSPI flash boot and OSPI flash boot on J721E platform is not possible due to this limitation. This commit adds lookup functions spl_spi_boot_bus() and spl_spi_boot_cs for identifying the flash device based on the selected boot device, when not overridden the lookup functions are weakly defined in common/spl/spl_spi.c.

Some image types (e.g. kwbimage v1) store the offset to SPL binary and offset to U-Boot proper binary in their headers. To avoid reading SPL binary when loading U-Boot proper, add support for specifying offset in struct spl_image_info, which defines the offset from the beginning of the header and the beginning of the executable data.

2021-04-19Revert "spl: Drop bd_info in the data section"Alexandru Gagniuc
This reverts commit 38d6b7ebdaee3e0e8426ef1b9df88bdce8ae2e75. struct global_data contains a pointer to the bd_info structure. This pointer was populated spl_set_bd() to a pre-allocated bd_info in the ".data" section. The referenced commit replaced this mechanism to one that uses malloc(). That new mechanism is only used if SPL_ALLOC_BD=y. which very few boards do. The result is that (struct global_data)->bd is NULL in SPL on most platforms. This breaks falcon mode, since arch_fixup_fdt() tries to access (struct global_data)->bd and set the "/memory" node in the devicetree. The result is that the "/memory" node contains garbage values, causing linux to panic() as it sets up the page table. Instead of trying to fix the mess, potentially causing other issues, revert to the code that worked, while this change is reworked. Signed-off-by: Alexandru Gagniuc <[email protected]>
2021-03-12spl: test: Add a test for spl_load_simple_fit()Simon Glass
As an example of an SPL test, add a new test for loading a FIT within SPL. This runs on sandbox_spl. For this to work, the text base is adjusted so that there is plenty of space available. While we are here, document struct spl_load_info properly, since this is currently ambiguous. This test only verifies the logic path. It does not actually check that the image is loaded correctly. It is not possible for sandbox's SPL to actually run u-boot.img since it currently includes u-boot.bin rather than u-boot. Further work could expand the test in that direction.

It is useful to be able to figure out which phase we are loading next and which phase we came from. Add some functions to handle this as well as returning the name of a phase. This allows messages like "Booting to x" where x is the next phase. At present, TPL says 'Jumping to U-Boot' at the end, when in fact it is jumping to SPL.

This uses up space in the SPL binary but it always starts as zero. Also some boards cannot support data in TPL (e.g. Intel Apollo Lake). Use malloc() to allocate this structure instead, by moving the init a little later, after malloc() is inited. Make this function optional since it pulls in malloc().

2020-05-10imx: imx8qm/qxp: Recover SPL data section for partition rebootPeng Fan
When doing partition reboot, the boot image won't be reloaded by ROM, it is just CPU reset to boot entry. The SW has to keep the boot image inside the RAM unchanged. It includes both the TEXT section and DATA section. For SPL, the problem is DATA section will be updated at runtime, so in next partition reboot the data is not same as the initial value from cold boot. If any code depends on the initial value, then it will have problem. This patch introduces a mechanism to recover the data section for partition reboot. It adds a new section in image for saving data section. When from cold boot, the data section will be saved to that new section at SPL early phase. When from partition reboot, the data section will be restored from the new section. Signed-off-by: Ye Li <[email protected]> Signed-off-by: Peng Fan <[email protected]>

RISC-V OpenSBI is an open-source implementation of the RISC-V Supervisor Binary Interface (SBI) specification. It is required by Linux and U-Boot running in supervisor mode. This patch adds support for booting via the OpenSBI FW_DYNAMIC firmware. It supports OpenSBI version 0.4 and higher. In this configuration, U-Boot SPL starts in machine mode. After loading OpenSBI and U-Boot proper, it will start OpenSBI. All necessary parameters are generated by U-Boot SPL and are passed to OpenSBI. U-Boot proper is started in supervisor mode by OpenSBI. Support for OpenSBI is enabled with CONFIG_SPL_OPENSBI. An additional configuration entry, CONFIG_SPL_OPENSBI_LOAD_ADDR, is used to specify the load address of the OpenSBI firmware binary. It is not used directly in U-Boot and instead is intended to make the value available to scripts such as FIT configuration generators.

To address the need being able to use this infrastructure to load arbitrary image files go ahead and refactor it as follows: - Refactor existing spl_mmc_load_image function into superset function, accepting additional arguments such as filenames and media load offset (same concept can also be applied toother spl_XXX_load_image functions) - Extend the loader function to "remember" their peripheral initialization status so that the init is only done once during the boot process, - Extend the FIT image loading function to allow skipping the parsing/ processing of the FIT contents (so that this can be done separately in a more customized fashion) - Populate the SPL_LOAD_IMAGE_METHOD() list with a trampoline function, invoking the newly refactored superset functions in a way to maintain compatibility with the existing behavior This refactoring initially covers MMC/SD card loading (RAW and FS-based).
