efi_loader: update the timing of enabling and disabling EFI watchdog

2022-02-26T06:37:01+00:00

UEFI specification requires that 5 minutes watchdog timer is
armed before the firmware's boot manager invokes an EFI boot option.
This watchdog timer is updated as follows, according to the
UEFI specification.

 1) The EFI Image may reset or disable the watchdog timer as needed.
 2) If control is returned to the firmware's boot manager,
    the watchdog timer must be disabled.
 3) On successful completion of EFI_BOOT_SERVICES.ExitBootServices()
    the watchdog timer is disabled.

1) is up to the EFI image, and 3) is already implemented in U-Boot.
This patch implements 2), the watchdog is disabled when control is
returned to U-Boot.

In addition, current implementation arms the EFI watchdog at only
the first "bootefi" invocation. The EFI watchdog must be armed
in every EFI boot option invocation.

cmd: clk: replace clk_lookup by uclass_get_device_by_name

2022-02-25T06:41:04+00:00

The function clk_lookup can be replaced by a direct call
to uclass_get_device_by_name for UCLASS_CLK.

This patch removes duplicated codes by the generic DM API and avoids
issue in clk_lookup because result of uclass_get_device wasn't tested;
when ret < 0, dev = NULL and dev->name is invalid, the next function
call strcmp(name, dev->name) causes a crash.

cmd/dfu: Enable 'dfu list' command without DFU_OVER_USB

2022-02-11T16:29:23+00:00

Since dfu is not only used for USB, and some platform only
supports DFU_OVER_TFTP or EFI capsule update, dfu_alt_info
is defined on such platforms too.

For such platform, 'dfu list' command is useful to check
how the current dfu_alt_info setting is parsed.

cmd: wrong printf() code in do_test_stackprot_fail()

strlen() returns size_t. So we should use %zu to print it.
