treewide: Kconfig: use bool instead of tristate

2026-07-10T21:45:57Z

U-Boot does not support modules, so having tristate options is useless. Therefore this patch does a blind replace of all tristate options to bool tree-wide.

usb: cdns3: use VBUS Valid to determine role for dr_mode OTG

2026-02-16T14:08:43Z

The cdns3_bind() function is responsible for identifying the appropriate driver to bind to the USB Controller's device-tree node. If the device-tree node has the 'dr_mode' property set to 'otg', the existing approach fails to bind a driver, leading to loss of functionality. To address this, use the VBUS Valid field of the OTG Status register to determine the role as follows: - If VBUS Valid field is set, it indicates that a USB Host is supplying power and the Controller should assume the Peripheral role. - If VBUS Valid field is clear, it indicates the absence of a USB Host and the Controller should assume the Host role. Additionally, when 'dr_mode' happens to be 'otg' and the STRAP settings are not specified, use VBUS Valid to determine the role in cdns3_drd_init() and assign it to cdns->dr_mode.

dm: core: Default to using DEVRES outside of xPL

2026-01-09T15:08:14Z

The devm alloc functions that we have may follow the Linux kernel model where allocations are (almost always) automatically free()'d. However, quite often we don't enable, in full U-Boot, the tracking and free()'ing functionality. This in turn leads to memory leaks because the driver author expects that since the functions have the same name as in the Linux Kernel they have the same behavior. In turn we then get functionally correct commits such as commit 00e1fed93c8c ("firmware: ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually add these calls. Rather than manually tracking allocations and implementing free()s, rework things so that we follow expectations by enabling the DEVRES functionality (outside of xPL phases). This turns DEVRES from a prompted symbol to a symbol that must be select'd, and we now remove our non-managed alloc/free functions from outside of xPL builds.

usb: cdns3: Do not access memory after free

2025-08-29T11:12:41Z

The call to cdns3_gadget_ep_free_request will free priv_req so do the call to list_del_init which accesses the memory pointed to by priv_req before the free. This issue was found by Smatch. Signed-off-by: Andrew Goodbody Reviewed-by: Siddharth Vadapalli

Kbuild: Always use $(PHASE_)

2025-04-11T18:16:44Z

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in. For consistency, bring this down to a single macro and use "$(PHASE_)" only. Signed-off-by: Tom Rini
