Freescale is using the 1.0.0 branch to host all patches done on top of
the initial 3.10.17-1.0.0 GA release.

As you can see on the log below, the top commit (the one referenced on
the SRCREV) is also the one used for the tag

commit 33597e348b2d60dd5c71890ef7b7d3d3fd6e4e97 (tag:
rel_imx_3.10.17_1.0.2_ga, freescale/imx_3.10.17_1.0.0_ga)

    crypto: testmgr - avoid DMA mapping from text, rodata, stack

    With DMA_API_DEBUG set, following warnings are emitted
    (tested on CAAM accelerator):
    DMA-API: device driver maps memory from kernel text or rodata
    DMA-API: device driver maps memory from stack
    and the culprits are:
    -key in __test_aead and __test_hash
    -result in __test_hash

    MAX_KEYLEN is changed to accommodate maximum key length from
    existing test vectors in crypto/testmgr.h (131 bytes) and rounded.

So what Lauren did was to adjust the branch name (for BitBake's
fetcher to be able to validate the hash existence) and bump the

In future, if a 3.10.17-1.0.3 is released, the only change will be the
SRCREV bump.
