So, yes, grabbing the series from the above link and applying it on top
of master, and making builds work with fake binaries would be very
helpful.  As best I can tell there's still something missing with making
fake blobs link and not fail.  For example, imx8mm_venice is part of the
series above but still fails with 'make BINMAN_FAKE_EXT_BLOBS=1 ...':
Image 'main-section:u-boot-spl-ddr' has faked external blobs and is non-functional: lpddr4_pmu_train_1d_imem.bin lpddr4_pmu_train_1d_dmem.bin lpddr4_pmu_train_2d_imem.bin lpddr4_pmu_train_2d_dmem.bin
Image 'main-section' is missing external blobs and is non-functional: atf_blob blob-ext
Wrote map file './imx-boot.map' to show errors
binman: Node '/binman/imx-boot/blob-ext at 1': Offset 0x0 (0) overlaps with previous entry '/binman/imx-boot/uboot' ending at 0x1aee08 (1764872)

And that last error is the real problem.
