From: Simon Glass <sjg@chromium.org> For a fake go, we should tell the event not to actually do anything irreversable, so pass the flag along. Move the enum into a separate event_decl.h header file since otherwise we must include bootm.h which causes a breakage with qemu-ppce500 We also don't want to pull event.h into the tools build, since it uses types like u8 which are not available outside U-Boot Signed-off-by: Simon Glass <sjg@chromium.org> --- boot/bootm_final.c | 13 ++++++++----- include/bootm.h | 13 +------------ include/event.h | 10 ++++++++++ include/event_decl.h | 27 +++++++++++++++++++++++++++ 4 files changed, 46 insertions(+), 17 deletions(-) create mode 100644 include/event_decl.h diff --git a/boot/bootm_final.c b/boot/bootm_final.c index 7594880399e..881d737ce67 100644 --- a/boot/bootm_final.c +++ b/boot/bootm_final.c @@ -17,6 +17,7 @@ __weak void board_quiesce_devices(void) void bootm_final(enum bootm_final_t flags) { + struct event_bootm_final final; int ret; printf("\nStarting kernel ...%s\n\n", flags & BOOTM_FINAL_FAKE ? @@ -43,15 +44,17 @@ void bootm_final(enum bootm_final_t flags) */ dm_remove_devices_active(); - ret = event_notify_null(EVT_BOOTM_FINAL); + final.flags = flags; + ret = event_notify(EVT_BOOTM_FINAL, &final, sizeof(final)); if (ret) { printf("Event handler failed to finalise (err %dE\n", ret); return; } + if (!(flags & BOOTM_FINAL_FAKE)) { + bootm_disable_interrupts(); - bootm_disable_interrupts(); - - if (!(flags & BOOTM_FINAL_NO_CLEANUP)) - cleanup_before_linux(); + if (!(flags & BOOTM_FINAL_NO_CLEANUP)) + cleanup_before_linux(); + } } diff --git a/include/bootm.h b/include/bootm.h index b026e1dd80d..392825841e9 100644 --- a/include/bootm.h +++ b/include/bootm.h @@ -7,6 +7,7 @@ #ifndef _BOOTM_H #define _BOOTM_H +#include <event_decl.h> #include <image.h> struct boot_params; @@ -16,18 +17,6 @@ struct cmd_tbl; #define BOOTM_ERR_OVERLAP (-2) #define BOOTM_ERR_UNIMPLEMENTED (-3) -/** - * enum bootm_final_t - flags to control bootm_final() - * - * @BOOTM_FINAL_FAKE: true to do everything except actually boot; it then - * returns to the caller - * @BOOTM_FINAL_NO_CLEANUP: true to skip calling cleanup_before_linux() - */ -enum bootm_final_t { - BOOTM_FINAL_FAKE = BIT(0), - BOOTM_FINAL_NO_CLEANUP = BIT(1), -}; - /** * struct bootm_info() - information used when processing images to boot * diff --git a/include/event.h b/include/event.h index a68be9fc1e8..5fecaa66e80 100644 --- a/include/event.h +++ b/include/event.h @@ -12,6 +12,7 @@ #include <dm/ofnode_decl.h> #include <linux/types.h> +#include <event_decl.h> /** * enum event_t - Types of events supported by U-Boot @@ -260,6 +261,15 @@ union event_data { struct event_ft_fixup_f { oftree tree; } ft_fixup_f; + + /** + * struct event_bootm_final - State information + * + * @flags: Flags passed to bootm_final() + */ + struct event_bootm_final { + enum bootm_final_t flags; + } bootm_final; }; /** diff --git a/include/event_decl.h b/include/event_decl.h new file mode 100644 index 00000000000..483ae687e5a --- /dev/null +++ b/include/event_decl.h @@ -0,0 +1,27 @@ +/* SPDX-License-Identifier: GPL-2.0+ */ +/* + * Declarations needed by events + * + * Copyright 2025 Simon Glass <sjg@chromium.org> + */ + +#ifndef __event_decl_h +#define __event_decl_h + +#include <linux/bitops.h> + +/** + * enum bootm_final_t - flags to control bootm_final() + * + * Note that this is defined in event.h since it is used by events + * + * @BOOTM_FINAL_FAKE: true to do everything except actually boot; it then + * returns to the caller + * @BOOTM_FINAL_NO_CLEANUP: true to skip calling cleanup_before_linux() + */ +enum bootm_final_t { + BOOTM_FINAL_FAKE = BIT(0), + BOOTM_FINAL_NO_CLEANUP = BIT(1), +}; + +#endif -- 2.43.0
