We do it in meta-fsl-arm as below:

ESCRIPTION = "U-boot bootloader mxsboot tool"
LICENSE = "GPLv2+"
LIC_FILES_CHKSUM = "file://Licenses/README;md5=c7383a594871c03da76b3707929d2919"
SECTION = "bootloader"
DEPENDS = "openssl"
PROVIDES = "u-boot-mxsboot"

PV = "v2014.10+git${SRCPV}"

SRCREV = "75ce95e627609c9b9e537e935e69c4ecef26c8f7"
SRCBRANCH = "patches-2014.10"
SRC_URI = "git://github.com/Freescale/u-boot-imx.git;branch=${SRCBRANCH}"

S = "${WORKDIR}/git"

inherit fsl-u-boot-localversion

EXTRA_OEMAKE = 'HOSTCC="${CC} ${CPPFLAGS}" HOSTLDFLAGS="-L${libdir}
-L${base_libdir}" HOSTSTRIP=true CONFIG_MX28=y'

do_configure () {
    oe_runmake sandbox_defconfig
}

do_compile () {
    oe_runmake tools-only
}

do_install () {
    install -d ${D}${bindir}
    install -m 0755 tools/mxsboot ${D}${bindir}/uboot-mxsboot
    ln -sf uboot-mxsboot ${D}${bindir}/mxsboot
}

BBCLASSEXTEND = "native nativesdk"
