2023-10-19riscv: kconfig: introduce SPL_LOAD_FIT_OPENSBI_OS_BOOT symbolRandolph
Introduce common Kconfig symbol for riscv architecture. This symbol SPL_LOAD_FIT_OPENSBI_OS_BOOT is like falcon mode on ARM, the Falcon boot is a shortcut boot method for SD/eMMC targets. It skips the loading the RAM version U-Boot. Instead, it will loads the FIT image and boots directly to Linux. When SPL_OPENSBI_OS_BOOT is enabled, linux.itb is created after compilation instead of the default u-boot.itb. It initialises memory with the U-Boot SPL at the first stage, just as a normal boot process does at the beginning. Instead of jumping to the U-Boot proper from OpenSBI before booting the Linux kernel, the RISC-V falcon mode process jumps directly to the Linux kernel to gain shorter booting time.

2023-10-18Merge branch '2023-10-17-spl-test-some-load-methods'Tom Rini
To quote the author: This series adds some tests for various SPL load methods, with the intent of helping debug v6 of [1]. With that in mind, notable omissions include NAND and ROMAPI, which both lack sandbox implementations, and OS_BOOT, which I have deferred due to its complexity. Semihosting is also omitted, but I think we can test that with qemu. In order to test all of these methods, we must first generate suitable images, possibly on filesystems. While other tests have historically generated these images using external tools (e.g. mkimage, mkfs, etc.), I have chosen to generate them on the fly. This is for a few reasons: - By removing external dependencies on pytest to create certain files, the tests become self-contained. This makes them easier to iterate on and debug. - By generating tests at runtime, we can dynamically vary the content. This helps detect test failures, as even if tests are loaded to the same location, the expected content will be different. - We are not testing the image parsers themselves (e.g. spl_load_simple_fit or fs_read) but rather the load methods (e.g. spl_mmc_load_image). It is unnecessary to exercise full functionality or generate 100% correct images. - By reducing functionality to only what is necessary, the complexity of various formats can often be greatly reduced. This series depends on [2-3], which are small fixes identified through this patch set. The organization of patches in this series is as follows: - General fixes for bugs which are unlikely to be triggered outside of this series - Changes to IMX8 container images to facilitate testing - General prep. work, particularly regarding linker issues - The tests themselves Passing CI at [4].

Add test for the SPI load method. This one is pretty straightforward. We can't enable FIT_EXTERNAL with LOAD_FIT_FULL because spl_spi_load_image doesn't know the total image size and has to guess from fdt_totalsize.

Add a test for the NOR load method. Since NOR is memory-mapped we can substitute a buffer instead. The only major complication is testing LZMA decompression. It's too complex to implement LZMA compression in a test, and we have no in-tree compressor, so we just include some pre-compressed data.

2023-10-17test: spl: Add a test for the NET load methodSean Anderson
Add a test for loading U-Boot over TFTP. As with other sandbox net routines, we need to initialize our packets manually since things like net_set_ether and net_set_udp_header always use "our" addresses. We use BOOTP instead of DHCP, since DHCP has a tag/length-based format which is harder to parse. Our TFTP implementation doesn't define as many constants as I'd like, so I create some here. Note that the TFTP block size is one-based, but offsets are zero-based. In order to avoid address errors, we need to set up/define some additional address information settings. dram_init_banksize would be a good candidate for settig up bi_dram, but it gets called too late in board_init_r.

Returning a negative value from a unit test doesn't automatically fail the test. We have to fail an assertion. Modify the test to do so. This now causes the test to count as a failure on VPL.

Sandbox unit tests in U-Boot proper load a test device tree to have some devices to work with. In order to do the same in SPL, we must enable SPL_OF_REAL. However, we already have SPL_OF_PLATDATA enabled. When generating platdata from a devicetree, it is expected that we will not need devicetree access functions (even though SPL_OF_CONTROL is enabled). This expectation does not hold for sandbox, so allow user control of SPL_OF_REAL.

2023-10-17arm: imx: Check header before calling spl_load_imx_containerSean Anderson
Make sure we have an IMX header before calling spl_load_imx_container, since if we don't it will fail with -ENOENT. This allows us to fall back to legacy/raw images if they are also enabled. This is a functional change, one which likely should have been in place from the start, but a functional change nonetheless. Previously, all non-IMX8 images (except FITs without FIT_FULL) would be optimized out if the only image load method enabled supported IMX8 images. With this change, support for other image types now has an effect. There are seven boards with SPL_LOAD_IMX_CONTAINER enabled: three with SPL_BOOTROM_SUPPORT: imx93_11x11_evk_ld imx93_11x11_evk imx8ulp_evk and four with SPL_MMC: deneb imx8qxp_mek giedi imx8qm_mek All of these boards also have SPL_RAW_IMAGE_SUPPORT and SPL_LEGACY_IMAGE_FORMAT enabled as well. However, none have FIT support enabled. Of the six load methods affected by this patch, only SPL_MMC and SPL_BOOTROM_SUPPORT are enabled with SPL_LOAD_IMX_CONTAINER. spl_romapi_load_image_seekable does not support legacy or raw images, so there is no growth. However, mmc_load_image_raw_sector does support loading legacy/raw images. Since these images could not have been booted before, I have disabled support for legacy/raw images on these four boards. This reduces bloat from around 800 bytes to around 200. There are no in-tree boards with SPL_LOAD_IMX_CONTAINER and AHAB_BOOT both enabled, so we do not need to worry about potentially falling back to legacy images in a secure boot scenario. Future work could include merging imx_container.h with imx8image.h, since they appear to define mostly the same structures. Signed-off-by: Sean Anderson <[email protected]>

2023-10-17Revert "fs: ext4: check the minimal partition size to mount"Sean Anderson
This check breaks small partitions (under 1024 blocks) because part_length is in units of part.blksz and not bytes. Given the purpose of this function, we really want to make sure the partition is SUPERBLOCK_START + SUPERBLOCK_SIZE (2048) bytes so we can call ext4_read_superblock without error. The obvious solution is to convert callers from things like ext4fs_mount(part_info.size) to ext4fs_mount(part_info.size * part_info.blksz); However, I'm not really a fan of the bloat that would cause, especially since the error is now suppressed.

This way, architecture code can define a default architecture specific implementation of arch_spl_mmc_get_uboot_raw_sector(), while the board code can override that using board_spl_mmc_get_uboot_raw_sector() which takes precedence over the architecture code. In some sort of unlikely special case where code has to take precedence over board code too, the spl_mmc_get_uboot_raw_sector() is still left out to be a weak function, but it should be unlikely that this is ever needed to be overridden.
