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: gadget: f_mass_storage: Disable eps during disconnect

2026-06-26T09:05:21Z

When trying two ums commands in a row, the second one no longer enumerates properly from the host. This happens since commit 59310d1ecb9f ("usb: gadget: introduce 'enabled' flag in struct usb_ep") causing usb_ep_enable() to return early when ep->enabled is already set. Gadget function drivers (such as f_fastboot or f_mass_storage) implement a disable() function which is called whenever we are done using the gadget. Because f_mass_storage driver does not disable the endpoints, ep->enabled will never be set to false again. This can be reproduced on the STM32MP157C-DK2 or the Khadas VIM3 boards. Add calls to usb_ep_disable() as done in linux [1] to fix this.

usb: f_sdp: handle the spl load function failure

2026-06-26T09:01:42Z

Current implementation does not check the return value of spl load function. If the spl load is failed, SPL may meet crash due to spl_image variable is not initialized. Add the failure check, so SPL can print and stop with error.

treewide: move bi_dram[] from bd to gd

2026-06-25T00:13:24Z

Currently, the bi_dram[] information is stored in the board info structure (bd). Because bd is only valid after reserve_board(), dram_init_banksize() must be called late in the initialization process. This limitation is problematic, as it forces us to rely on a variety of bespoke functions to determine board RAM, bank memory sizes, and other early setup requirements. By moving bi_dram[] into the global data (gd), we can run it earlier. This is particularly convenient since boards define their own dram_init_banksize() routines, which do not always rely on parsing Device Tree (DT) memory nodes. Additionally, U-Boot defaults to relocating to the top of the first memory bank. While boards currently use custom functions to override this behavior, having the DRAM bank information available earlier in gd makes relocating to a different bank trivial and standardizes the process.

usb: tcpm: fix inverted poll condition in tcpm_pd_transmit()

2026-06-18T14:48:16Z

The read_poll_timeout() macro breaks out of its loop when the condition evaluates to true. The current code uses "!tx_complete" as the condition, which means it exits immediately when tx_complete is false (i.e., transmission has NOT completed yet), rather than waiting for completion. Fix the condition to "tx_complete" so that the poll loop waits until the TCPC signals transmission success/failure/discard before proceeding. Without this fix, tcpm_pd_transmit() returns before the TCPC has finished transmitting, causing the PD state machine to proceed with stale tx_status values.

usb: gadget: atmel: use calloc() to allocate endpoint list

2026-06-15T07:15:25Z

malloc() doesn't zero out memory, leaving ep->ep.enabled uninitiated, which could make this flag falsely true. In next usb_ep_enable() call since this flag is true, ep->ops->enable() will be skipped. Then usb_ep_queue() will fail on uninitialized endpoint.

treewide: prefer func over FUNCTION and __PRETTY_FUNCTION__

2026-06-10T20:49:46Z

__FUNCTION__ and __PRETTY_FUNCTION__ are gcc extensions that predate the C99 __func__ identifier. scripts/checkpatch.pl emits a warning for any new use of __FUNCTION__ and recommends __func__ instead. In C (unlike C++) __PRETTY_FUNCTION__ is identical to __func__ because C function names do not carry signature information, so the distinction has no behavioural effect here. The majority of the tree already uses __func__, but a handful of older files in arch/, board/, boot/, drivers/, examples/ and include/ still carry the gcc spellings (55 occurrences of __FUNCTION__ across 19 files plus one __PRETTY_FUNCTION__ in drivers/usb/musb-new/omap2430.c). Convert them all to the C99 form so the tree is consistent and new patches in these areas do not have to follow an outdated local style. Ten "Unnecessary ftrace-like logging - prefer using ftrace" warnings remain on the printf("%s\n", __func__) and dbg("%s\n", __func__) function-entry traces in drivers/net/rtl8169.c (behind DEBUG_RTL8169* preprocessor guards) and drivers/usb/host/ohci-hcd.c. checkpatch matches the literal "%s\n", __func__ shape regardless of the wrapper, so silencing those warnings would require changing the debug message text or removing the traces entirely.
