[U-Boot] Regression in U-boot v2019-07-rcX

[Andy Shevchenko]

Hi!

I have noticed today the regression in newer U-Boot.
For now I'm not sure which version is affected first. At least v2019.07-rc4
behaves badly.

Under badly I mean the following. Consider the output at the boot time:

U-Boot 2019.07-rc4-00012-gcea7942d57 (Jun 12 2019 - 16:08:09 +0300)

CPU:   Intel(R) Atom(TM) CPU  U1000  @  500MHz
DRAM:  980.6 MiB
MMC:   mmc at ff3fc000: 0, mmc at ff3fa000: 1
Loading Environment from MMC... OK
In:    serial
Out:   serial
Err:   serial
Net:   No ethernet found.
Hit any key to stop autoboot:  0 

Note lines started with DRAM: and MMC:. Now the 4 seconds (!) time is passed
between them.

On top of that DFU seems twice slower (on the glance, I haven't measure with
`time` yet).

Any ideas, while I'll try to allocate some time to investigate myself?

P.S. The board I'm testing with is Intel Edison. I think no need to tell that
nothing has been changed except the base (I'm rebased my stuff on top of latest
and greatest U-Boot releases).
