[PATCH v2 00/29] test: spl: Test some load methods
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].

spl_image_info.name contains a reference to legacy_img_hdr. If we allocate the latter on the stack, it will be clobbered after we return. This was addressed for NAND back in 06377c5a1fc ("spl: spl_legacy: Fix NAND boot on OMAP3 BeagleBoard"), but that commit didn't fix NOR.

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.

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.
There are several places in the tree where conditions involving OF_PLATDATA or OF_REAL no longer function correctly when both of these options can be selected at the same time. Adjust these conditions accordingly.

Why do would you disable the sandbox file system in SPL for CONFIG_SANDBOX_SPL=y?
I cannot see that this is necessary to enable the unit tests you are striving for. Instead we should extend the SPL unit tests to sandbox_spl_defconfig in the long run.

Why do would you disable the sandbox file system in SPL for CONFIG_SANDBOX_SPL=y?
It was never enabled in the first place, since we never had fs.c compiled in SPL before. This just fixes linking.
I cannot see that this is necessary to enable the unit tests you are striving for. Instead we should extend the SPL unit tests to sandbox_spl_defconfig in the long run.
The purpose of the sandbox filesystem is to test routines which use the filesystem API in U-Boot. However, there are very few which do so in SPL. SPL_FS_LOADER is the only one I know of off the top of my head. However, FS_LOADER is tested in U-Boot proper. I don't think there is a pressing need to enable the sandbox filesystem in SPL.

We're just moving the code around for now, and this should get replaced by lwip in time.
If we sent a DHCP packet and get a BOOTP response from the server, we shouldn't try to send a DHCPREQUEST packet, since it won't be DHCPACKed. Transition straight to BIND. This is only enabled for UNIT_TEST to avoid bloat, since I suspect the number of BOOTP servers in the wild is vanishingly small.

While it is convenient for tests to implement a BOOTP server, there are effectively no BOOTP servers in the wild. However, BOOTP is commonly enabled in U-Boot. In an effort to avoid growing most U-Boots for testing purposes, I enabled this path just for unit tests. That said, only 6 boards enable SPL_ETH, so maybe it is not too bad.

And so long as this doesn't lead to overflowing them, OK. But size is not infinite there, am335x_evm and am43xx_hs_evm are both a bit constrained.
Several SPL functions try to avoid performing initialization twice by caching devices. This is fine for regular boot, but does not work with UNIT_TEST, since all devices are torn down after each test. Add some functions to invalidate the caches which can be called before testing these load methods.

All "physical" addresses in SPL must be converted to virtual addresses before access in order for sandbox to work. Add some calls to map_sysmem in appropriate places. We do not generally call unmap_sysmem, since we need the image memory to still be mapped when we jump to the image. This doesn't matter at the moment since unmap_sysmem is a no-op.

In order to make adding new spl unit tests easier, especially when they may have many dependencies, add some Kconfigs for the existing image test. Split it into the parts which are generic (such as callbacks) and the test-specific parts.

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. This is because the fname of SPL (and U-Boot) is generated with make_exec in os_jump_to_image. The original name of SPL is gone, and we can't determine the name of U-Boot from the generated name.

This add some basic functions to create images, and a test for said functions. This is not intended to be a test of the image parsing functions, but rather a framework for creating minimal images for testing load methods. That said, it does do an OK job at finding bugs in the image parsing directly.
Since we have two methods for loading/parsing FIT images, add LOAD_FIT_FULL as a separate CI run.

Add some functions for creating fat/ext2 filesystems with a single file and a test for them. Filesystems require block devices, and it is easiest to just use MMC for this. To get an MMC, we must also pull in the test device tree. SPL_TIMER is necessary for SPL_MMC, perhaps because it uses a timeout.

Changes in v2: - Explicitly invalidate FAT block device cache before testing - Remove unused dm.h include in spl_load.c - Add note about why we enable SPL_TIMER - Split off ext/-T changes into their own commits

Add some functions for creating fat/ext2 filesystems with a single file and a test for them. Filesystems require block devices, and it is easiest to just use MMC for this. To get an MMC, we must also pull in the test device tree. SPL_TIMER is necessary for SPL_MMC, perhaps because it uses a timeout.

Changes in v2:
- Explicitly invalidate FAT block device cache before testing
- Remove unused dm.h include in spl_load.c
- Add note about why we enable SPL_TIMER

Add a test for spl_blk_load_image, currently used only by NVMe. Because there is no sandbox NVMe driver, just use MMC instead. Avoid falling back to raw images to make failures more obvious.

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.

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. This data was generated through something like
generate_data(plain, plain_size, "lzma") cat plain.dat | lzma | hexdump -C
and was cleaned up further in my editor.

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. This doesn't include external data, so loading it will fail.

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].
