[yocto] [meta-raspberrypi] morty release ?

[Mirza Krak]

Hi.

I have some questions and remarks and hopefully someone here can answer them.

The meta-raspberrpi layer is missing a morty release? Any time frame
of when this will be added?

There is currently a issue when using U-boot due to some updates in
RPi boot firmware. See [1] and [2]. Which should be noted/resolved
before a morty release?

To provide some more information about above mentioned problem. If you
use the current firmware files (20161030 in meta-raspberrypi) together
with U-boot (2016.03) you lose the console on U-boot and on Linux
kernel. This is due to the fact that "newer" firmware sets a default
uart clock to 48 MHz, but U-boot has a hard-coded value of 3 MHz, and
since we yet do not support to "forward" the patched DTB provided by
the firmware from U-boot to Linux we also break console on Linux.

The "default" values has been updated in Linux, see [2]. But if you
use that updated Linux kernel there is a mismatch between u-boot and
Linux. Should be noted that U-boot 2016.11 does not have this problem
since it does not try to initialize the UART port at all and only
relies on firmware to set it up correctly (see [3]).

Hope I made sense here :).
