Marek Vasut [Sun, 10 Apr 2022 04:46:52 +0000 (06:46 +0200)]
Revert "env: Load env when ENV_IS_NOWHERE is only location selected"

This reverts commit 8d61237edbf6314a701cf78da2c5893a73ff5438.

This commit broke environment on literally every board I have access
to, with this revert in place, environment works as it should again.
The problem I observe with this patch is that saved environment in
either SPI NOR or eMMC is never used, the system always falls back
to default environment. The 'saveenv' command does succeed, but then
after reset, the default env is again used.

Furthermore, the commit introduced duplicate code in env_init(), this:
"
if (!prio) {
gd->env_addr = (ulong)&default_environment[0];
gd->env_valid = ENV_INVALID;

return 0;
}

if (ret == -ENOENT) {
gd->env_addr = (ulong)&default_environment[0];
gd->env_valid = ENV_INVALID;

return 0;
}
"

Furthermore, the commit is missing DCO SoB line.

Also note that upstream does not support UltraZed EG board, so
this might have been a patch pulled from downstream which did
depend on some other downstream behavior.

AKASHI Takahiro [Tue, 8 Mar 2022 11:36:45 +0000 (20:36 +0900)]
virtio: call device_probe() in scanning

virtio_init() enumerates all the peripherals that are to be materialised
with udevices(UCLASS_VIRIO) and creates particular device instances
(UCLASS_BlK or whatever else) as children.
On the other hand, device_probe() won't be invoked against those resultant
udevices unlike other ordinary device drivers do in the driver model.

This is particularly inconvenient when we want to add "event notification"
callback so that we will be able to automatically create all efi_disk
objects in a later patch.

With this patch applied, "virtio scan" will work in a similar way
to "scsi rescan", "usb start" or others in term of 'probe' semantics.

I didn't add this change to virtio_init() itself because this function
may be called in board_init_r() (indirectly in board_late_init())
before UEFI subsustem is initialized.

abuf: Correct a corner case with abuf_realloc()

If the buffer is empty and not allocated, then abuf_realloc() tries to
copy invalid data. This happens because an incorrect change to use
memdup() was added after the original code was written.
