From b2acf59baf917c3b4002c1b2094ddb46c03ab02e Mon Sep 17 00:00:00 2001 From: Alexey Romanov Date: Thu, 18 Apr 2024 13:01:29 +0300 Subject: fastboot: introduce 'oem board' subcommand Currently, fastboot protocol in U-Boot has no opportunity to execute vendor custom code with verifed boot. This patch introduce new fastboot subcommand fastboot oem board:, which allow to run custom oem_board function. Default implementation is __weak. Vendor must redefine it in board/ folder with his own logic. For example, some vendors have their custom nand/emmc partition flashing or erasing. Here some typical command for such use cases: - flashing: $ fastboot stage bootloader.img $ fastboot oem board:write_bootloader - erasing: $ fastboot oem board:erase_env Signed-off-by: Alexey Romanov Reviewed-by: Mattijs Korpershoek Reviewed-by: Quentin Schulz Link: https://lore.kernel.org/r/20240418100129.1691822-2-avromanov@salutedevices.com Signed-off-by: Mattijs Korpershoek --- drivers/fastboot/fb_command.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) (limited to 'drivers/fastboot/fb_command.c') diff --git a/drivers/fastboot/fb_command.c b/drivers/fastboot/fb_command.c index b8782bfa7fa..e6d58485817 100644 --- a/drivers/fastboot/fb_command.c +++ b/drivers/fastboot/fb_command.c @@ -43,6 +43,7 @@ static void oem_format(char *, char *); static void oem_partconf(char *, char *); static void oem_bootbus(char *, char *); static void oem_console(char *, char *); +static void oem_board(char *, char *); static void run_ucmd(char *, char *); static void run_acmd(char *, char *); @@ -114,6 +115,10 @@ static const struct { .command = "oem console", .dispatch = CONFIG_IS_ENABLED(FASTBOOT_CMD_OEM_CONSOLE, (oem_console), (NULL)) }, + [FASTBOOT_COMMAND_OEM_BOARD] = { + .command = "oem board", + .dispatch = CONFIG_IS_ENABLED(FASTBOOT_OEM_BOARD, (oem_board), (NULL)) + }, [FASTBOOT_COMMAND_UCMD] = { .command = "UCmd", .dispatch = CONFIG_IS_ENABLED(FASTBOOT_UUU_SUPPORT, (run_ucmd), (NULL)) @@ -549,3 +554,28 @@ static void __maybe_unused oem_console(char *cmd_parameter, char *response) else fastboot_response(FASTBOOT_MULTIRESPONSE_START, response, NULL); } + +/** + * fastboot_oem_board() - Execute the OEM board command.
