There are several problems with the above:

1) In my reply I mentioned that subpath is not the right option to use. Use
destsuffix instead.

2) You can't just do SRC_URI = twice, the second time it will just overwrite
the value from the first statement.

3) You'll need to specify name= for each item and then specify SRCREV for each
one ("${AUTOREV}" if you want to use the latest on the specified branch).

So you'll need something like:

SRC_URI = "git://ep-code.xtz.com/u-boot.git;branch=xxx-ep-20130823-3.0-alpha;protocol=ssh;name=uboot;destsuffix=git/uboot \
                     git://ep-code.xtz.com/x-load.git;branch=xxx-ep-20130823-3.0-alpha;protocol=ssh;name=xload;destsuffix=git/xload"
SRCREV_uboot = "${AUTOREV}"
SRCREV_xload = "${AUTOREV}"

Don't forget also to set S = "${WORKDIR}/git" as well.

Note that if you want to use ${SRCPV} in PV to get the source revision in
the version, you'll also need to set SRCREV_FORMAT to tell the system
how to compose SRCPV from the two SRCREV values e.g.

SRCREV_FORMAT = "uboot_xload"

Cheers,
Paul
