I've tested the current dwc2 FIFO configuration and found that USB device mode breaks in ECM mode when transmitting frames larger than 128 bytes. For example, large ICMP packets or iperf3 traffic cause the USB link to hang and eventually disconnect without any messages in dmesg. After switching to more conservative FIFO sizes, ECM becomes stable and no longer drops the connection. iperf3 now shows ~130 Mbit/s RX and ~100 Mbit/s TX on SG2002 (MilkV Duo 256M). Fix the FIFO sizes accordingly. Signed-off-by: Anton D.

2025-12-24mhi: host: Add support for loading dual ELF image formatQiang Yu
Currently, the FBC image contains a single ELF header followed by segments for both SBL and WLAN FW. However, TME-L (Trust Management Engine Lite) supported devices (e.g., QCC2072) require separate ELF headers for SBL and WLAN FW segments due to TME-L image authentication requirements. Current image format contains two sections in a single binary: - First 512KB: ELF header + SBL segments - Remaining: WLAN FW segments (raw data) The TME-L supported image format contains two complete ELF files in a single binary: - First 512KB: Complete SBL ELF file (ELF header + SBL segments) - Remaining: Complete WLAN FW ELF file (ELF header + WLAN FW segments) Download behavior: - Legacy: 1. First 512KB via BHI (ELF header + SBL) 2. Full image via BHIe - TME-L: 1. First 512KB via BHI (SBL ELF file) 2. Remaining via BHIe (WLAN FW ELF file only) Add runtime detection to automatically identify the image format by checking for the presence of a second ELF header at the 512KB boundary. When detected, MHI skips the first 512KB during WLAN FW download over BHIe as it is loaded in BHI phase.

2025-12-23PCI: Use resource_set_range() that correctly sets ->endIlpo Järvinen
__pci_read_base() sets resource start and end addresses when resource is larger than 4G but pci_bus_addr_t or resource_size_t are not capable of representing 64-bit PCI addresses. This creates a problematic resource that has non-zero flags but the start and end addresses do not yield to resource size of 0 but 1. Replace custom resource addresses setup with resource_set_range() that correctly sets end address as -1 which results in resource_size() returning 0. For consistency, also use resource_set_range() in the other branch that does size based resource setup.

2025-12-23PCI: endpoint: Avoid creating sub-groups asynchronouslyLiu Song
The asynchronous creation of sub-groups by a delayed work could lead to a NULL pointer dereference when the driver directory is removed before the work completes. The crash can be easily reproduced with the following commands: # cd /sys/kernel/config/pci_ep/functions/pci_epf_test # for i in {1..20}; do mkdir test && rmdir test; done BUG: kernel NULL pointer dereference, address: 0000000000000088 ...
