but in case of

bitbake fsl-image-mfgtool-initramfs

i will face with following error:

ERROR: Nothing PROVIDES 'u-boot-mfgtool' (but /media/mohsen/Board/fsl-community-bsp-w/sources/meta-freescale/recipes-fsl/images/fsl-image-mfgtool-initramfs.bb DEPENDS on or otherwise requires it)
u-boot-imx-mfgtool PROVIDES u-boot-mfgtool but was skipped: You cannot use UBOOT_MACHINE and UBOOT_CONFIG at the same time.
ERROR: Required build target 'fsl-image-mfgtool-initramfs' has no buildable providers.
