Configures the

<link linkend='var-IMAGE_FSTYPES'><filename>IMAGE_FSTYPES</filename></link>

Following is an example from the
|
||||
<filename>meta-fsl-arm</filename> layer.
|
||||
<literallayout class='monospaced'>
|
||||
UBOOT_CONFIG ??= "sd"
|
||||
UBOOT_CONFIG[sd] = "mx6qsabreauto_config,sdcard"
|
||||
UBOOT_CONFIG[eimnor] = "mx6qsabreauto_eimnor_config"
|
||||
UBOOT_CONFIG[nand] = "mx6qsabreauto_nand_config,ubifs"
|
||||
UBOOT_CONFIG[spinor] = "mx6qsabreauto_spinor_config"
|
||||
</literallayout>
|
||||
In this example, "sd" is selected as the configuration
|
||||
of the possible four for the
|
||||
<filename>UBOOT_MACHINE</filename>.
|
||||
The "sd" configuration defines "mx6qsabreauto_congif"
|
||||
as the value for <filename>UBOOT_MACHINE</filename>, while
|
||||
the "sdcard" specifies the
|
||||
<filename>IMAGE_FSTYPES</filename> to use for the U-boot
|
||||
image.
|
||||
</para>
