[db410c] 10 Second delay

[jwinarske]

I'm finding some odd interactions with timing. I suspect it's related to the programmer (target flash stub) used. Meaning it will vary depending on SoC target.

Once the flash stub is pushed via sahara it jumps into it's entry point. Depending on the flash stub used it may need to train the DDR, etc. So completion time varies on flash stub implementation (target implementation).

The current timeout/delay: https://github.com/andersson/qdl/blob/master/firehose.c#L617
I find dropping this timeout to 500 ms works reliably. This delay corresponds to the first entry of the listed log.

Then a default configuration is sent with a big default value. In the case of the apq8016 emmc flash stub it causes a timeout after re-config. Seems it might be better to read then modify, which would eliminate this additional timeout/delay.

Delay is ~10 seconds

Putting on my factory hat - that's really expensive :)

I'll look at this a bit more later.
