[fedora-arm] Struggling to boot Novena (IMX6) board with Fedora ARM kernels

[Martin Langhoff]

Hi folks!

(explicit CC appreciated, I'm subscribed in "no-mail" mode, thanks!)

I've been struggling for a few evenings trying to boot a fedora debug
kernel on a Novena (imx6) board. This board does boot with a much
non-debug kernel (it boots into Debian).

I have a nice kernel RPM with all the pactches needed, but it's a
debug rawhide kernel so pretty bloated. One of my hurdles right now is
that compressed kernel+initramfs size not fitting the mem segment
available: the board locks up if I load anything past 18M

Is this a frequent problem with u-boot boards and debug kernels? (This
shows my OLPC-distortion-field, I'm used to OpenFirmware).

I wonder, where can I poke to find out what's at 18M and can I put the
kernel + initramfs ina safe spot past that? This board has 4GB...

I grepped around the uboot source used here. It has the
CONFIG_SYS_SKIP_ARM_RELOCATION patch but it does not make use of it,
so AIUI it should put itself at the end of whatever RAM it knows how
to map...

thanks,
