Subject: [PATCH] bootstd: Scan all bootdevs in a boot_targets entry
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

|
When the boot_targets environment variable is used with the distro-boot
|
|
scripts, each device is included individually. For example, if there
|
|
are three mmc devices, then we will have something like:
|
|
|
|
boot_targets="mmc0 mmc1 mmc2"
|
|
|
|
In contrast, standard boot supports specifying just the uclass, i.e.:
|
|
|
|
boot_targets="mmc"
|
|
|
|
The intention is that this should scan all MMC devices, but in fact it
|
|
currently only scans the first.
|
|
|
|
Update the logic to handle this case, without required BOOTSTD_FULL to
|
|
be enabled.
|
|
|
|
I believe at least three people reported this, but I found two.
