Revert "dm: core: Simplify dm_probe_devices()"

2025-03-04T14:22:10Z

Unfortunately this change was not safe as some devices are bound before relocation, but we don't want to probe them. It causes 'raise: Signal # 8 caught' on jerry. Move the bootstage timer to after autoprobe in initf_dm() since the trace test does not tolerate any variance. This reverts commit 21dd873572a01d74bfdfceb7a30b056f8ccba187.

miiphy: define mii_devs with LIST_HEAD()

2025-03-04T14:03:47Z

When enabling net console and console multiplexing, a boot crash was observed using mtk_eth driver with stdin/stdout set to "serial,nc" in persistent environment: > CPU: MediaTek MT7981 > Model: OpenWrt One > DRAM: 1 GiB > Core: 35 devices, 15 uclasses, devicetree: separate > spi-nand: spi_nand spi_nand@0: Winbond SPI NAND was found. > spi-nand: spi_nand spi_nand@0: 128 MiB, block size: 128 KiB, page size: 2048, OOB size: 64 > Loading Environment from UBI...

During the mtk_eth driver initialization, mdio_register() will be called, and miiphy_get_dev_by_name() will then be called. The miiphy_get_dev_by_name() will check the list "mii_devs" to see if the passed device name exists. However the mii_devs is defined without initialization: > static struct list_head mii_devs; and the actual initialization is done in the following chain: initr_net -> eth_initialize -> eth_common_init -> miiphy_init Since initr_net() hasn't be called, iterating over the mii_devs will access to physical address 0 (mii_devs.next == NULL) and will cause the crash. The fix is to define mii_devs using: > static LIST_HEAD(mii_devs); As the "current_mii" is defined as a static variable, it will always be NULL in board_r stage and initializing it will NULL is unnecessary. So the entire miiphy_init() can be remove. Signed-off-by: Weijie Gao

vbe: Allow VBE to disable adding loadables to the FDT

2025-02-03T22:01:36Z

When VBE operates within VPL it does not want the FDT to be changed. Provide a way to disable this feature. Move the FIT_IMAGE_TINY condition out of spl_fit_record_loadable() so that both conditions are together. This makes the code easier to understand. Replace the existing fit_loaded member, which is no-longer used. Signed-off-by: Simon Glass

vbe: Provide VPL binman-symbols for the next phase

2025-02-03T22:01:36Z

Add support for moving from TPL->VPL->SPL so that the VPL build can fit properly into the boot flow. Use #ifdefs to avoid creating unwanted symbols which Binman would then try (and perhaps fail) to provide. Add debugging to indicate the next phase. Signed-off-by: Simon Glass

vbe: Support providing a linker script

Allow a linker script to be provided for VPL as it is for other U-Boot phases. Signed-off-by: Simon Glass

spl: Support selecting images based on phase in simple FIT

2025-02-03T22:01:36Z

At present the simple FIT-loader always loads images, ignoring whether they are intended for the next phase or not. VBE packages up several images in the same FIT, some destined for VPL and some for SPL. Add logic to check the phase before loading the image. Return -EPERM in that case and handle it gracefully. Fix a unnecessary re-computation of read_offset while here. Signed-off-by: Simon Glass

spl: Adjust debugging and xPL symbols

2025-02-03T22:00:42Z

The size of some malloc() fields has reduced on 64-bit machines, but the spl_reloc code was not updated. Fix this to avoid a compiler warning. Also update for the new xPL naming. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

lib: Allow crc16 code to be dropped

2025-02-03T22:00:42Z

This code is not necessarily needed in VPL, even if SPL uses it, so adjust the rules to allow it to be dropped. Do the same for the hash API. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

bloblist: add api to get blob with size

2025-01-28T06:59:21Z

bloblist_find function only returns the pointer of blob data, which is fine for those self-describing data like FDT. But as a common scenario, an interface is needed to retrieve both the pointer and the size of the blob data. Add a few ut test cases for the new api.

log: enable filtering on functions

Up to now we could only use log level, category, and file for filtering. Allow filtering on a list of functions. Signed-off-by: Heinrich Schuchardt
