[ANN] U-Boot v2020.04-rc4 released

Hey all,

So, I've gotten out of the habit of tagging rcs on cycle. This month I have been taking in changes sparingly and I'm not concerned that things have gone in that wouldn't have, if I had tagged -rc4/rc5 on schedule.

Things have been going to the -next branch as expected, and I think that will work out when things open up for v2020.07

So here now is -rc4 and I plan to make the final release on April 6th, as scheduled. Thanks all and stay safe out there!
