Configures the
<link linkend='var-UBOOT_MACHINE'><filename>UBOOT_MACHINE</filename></link>

for individual cases.

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>

<filename>UBOOT_CONFIG</filename> is handled, see the
