Sandbox Bootmeth
|
|
================
|
|
|
|
The sandbox bootmeth is only used for testing. It does not provide any facility
|
|
for booting an OS. While sandbox can do all the processing before the actual
|
|
boot, it is not connected in this bootmeth.
|
|
|
|
When invoked on a bootdev, this bootmeth pretends to find a bootflow and creates
|
|
the associated structure.
|
|
|
|
When the bootflow is booted, the bootmeth returns `-ENOTSUPP` indicating that it
|
|
is not supported.
|
|
|
|
The compatible string "u-boot,sandbox-bootmeth" is used for the driver. It is present
|
|
if `CONFIG_BOOTMETH_SANDBOX` is enabled.
