Depends on the definition of essential.
Serial and mmc works.
I said it was an easter egg since it was... well... quite a bit of surprise
that the same kernel started to fail for example in all audio operation when I
updated the u-boot, which I tend to do every now and then to see if there are
no regression.
So it was a nice surprise. Even the commit message agreed that it is going to
break the drivers:
Note that this is going to break the kernel drivers. But this
is the only way to get things fixed in the kernel.
Usually if I know I will going to break something intentionally I tend to send
warnings and give some grace periods for the interested guys to adopt.
And this is why people are not testing u-boot. We tend to have one working
binary moving from SD card to other and update it only, __only__ when it can
not be avoided.
If we work together, we should work together...
Do not take it personal. I just had tough days...
