2025-04-22Merge patch series "Enable UNIT_TEST for all qemu* generic targets"Tom Rini
Jerome Forissier <jerome.forissier@linaro.org> says: Enable CONFIG_UNIT_TEST in most of the configs/qemu*_defconfig files to increase test coverage in CI, and fix what needs to be fixed. Link: https://lore.kernel.org/r/20250416135744.1995084-1-jerome.forissier@linaro.org
2025-04-22Merge patch series "ut: fix print_guid() and enable UNIT_TEST for qemu_arm64"Tom Rini
Jerome Forissier <jerome.forissier@linaro.org> says: There is a bug in the print_guid() unit test in test/common/print.c when PARTITION_TYPE_GUID is not enabled but either CMD_EFIDEBUG or EFI are. The first patch fixes the issue and the second one enables UNIT_TEST in the qemu_arm64 defconfig so that the unit tests are run in CI (this platform has CMD_EFIDEBUG so the bug applies).

2025-04-22lib/uuid.c: use unique name for PARTITION_SYSTEM_GUIDJerome Forissier
The name defined for PARTITION_SYSTEM_GUID in list_guid[] depends on configuration options. It is "system" if CONFIG_PARTITION_TYPE_GUID is enabled or "System Partition" if CONFIG_CMD_EFIDEBUG or CONFIG_EFI are enabled. In addition, the unit test in test/common/print.c is incorrect because it expects only "system" (or a hex GUID). Make things more consistent by using a clear and unique name: "EFI System Partition" whatever the configuration, and update the unit test accordingly.

2025-04-22configs: enable CONFIG_UNIT_TEST for all qemu* generic targetsJerome Forissier
The qemu* "generic" targets (i.e. not those emulating a particular board) are typically used for testing as many features as possible, especially in CI so it makes sense to have UNIT_TEST enabled for all of the defconfigs for these targets. Not enabling UNIT_TEST in qemu-x86_defconfig due to: LD u-boot ld.bfd: section .rel.dyn VMA wraps around address space ld.bfd: section .start16 LMA [fffff800,fffff86f] overlaps section .rel.dyn LMA [ffffb77c,0002ac93] make: *** [Makefile:1824: u-boot] Error 1 Suggested-by: Tom Rini <trini@konsulko.com> Signed-off-by: Jerome Forissier <jerome.forissier@linaro.org>

2025-04-22i2c: omap24xx_i2c: support CONFIG for repeated start in DM_I2C xferAniket Limaye
Repeated Start Condition (Sr) can be used to transfer multiple i2c msgs without sending a Stop condition (P). So far, the driver default was to always send a Stop condition after every i2c msg. Add support for a config option (CONFIG_SYS_I2C_OMAP24XX_REPEATED_START) to disable sending the Stop condition by default. If this config is enabled, Stop condition will be sent only if explicitly requested in the msg flags OR if it is the last msg in the transfer. Consequently, handle the Repeated Start condition (Sr) in the next msg by not calling the wait_for_bb() check since it will simply timeout in the absence of a stop condition (BB will be 1 until Stop is programmed) Signed-off-by: Aniket Limaye <a-limaye@ti.com> Reviewed-by: Heiko Schocher <hs@denx.de>
2025-04-22i2c: omap24xx_i2c: Use new function __omap24_i2c_xfer_msg()Aniket Limaye
Remove __omap24_i2c_read/write() usage from omap_i2c_xfer() in favour of the more flexible __omap24_i2c_xfer_msg(). Consequently, these are also no longer needed when DM_I2C is enabled. New function __omap24_i2c_xfer_msg() will take care of individual read OR write transfers with a target device. It goes through below sequence: - Program the provided Target Chip address (OMAP_I2C_SA_REG) - Program the provided Data len (OMAP_I2C_CNT_REG) - Program the provided Control register flags (OMAP_I2C_CON_REG) - Read from or Write to the provided Data buffer (OMAP_I2C_DATA_REG) For a detailed programming guide, refer to the TRM[0] (12.1.3.4 I2C Programming Guide). This patch by itself should be a transparent change. However this is needed for implementing a proper Repeated Start (Sr) functionality for i2c_msgs. Previous implementation for omap_i2c_xfer called __omap24_i2c_read/write functions, with hardcoded addr=0 and alen=0 for each i2c_msg. Each of these calls would program the registers always with a Stop bit set, not allowing for a repeated start between i2c_msgs in the same xfer().

2025-04-21fs: exfat: Rework exfat_fs_readdir() to behave like exfat_fs_ls()Marek Vasut
The exfat_fs_readdir() depends on state created in exfat_fs_opendir(), but that state may be disrupted by fs_close() called by the FS layer in fs_opendir(), because exfat porting layer unmounts the filesystem in ->close() callback. To avoid this disruption, avoid creating state in exfat_fs_opendir(), cache only the directory name to list there, and rework exfat_fs_readdir() to work in a similar way to exfat_fs_ls(). That is, make exfat_fs_readdir() open the directory, look up specific entry, extract its properties to be reported to FS layer, and close the directory. This is slow, but avoids the disruption. The slowness does not affect regular 'ls' command, which uses exfat_fs_ls() fast path. Fixes: b86a651b646c ("fs: exfat: Add U-Boot porting layer") Signed-off-by: Marek Vasut <marex@denx.de>
2025-04-21fs: exfat: Inhibit "impossible" print on write to bogus fileMarek Vasut
