Hi
You are right. I used a different bootloader for the newer kernels, because of
another build system and did not think about it. The u-boot from github/gumstix
sets the memory timings different than the u-boot directly from denx.de.
I switched to the gumstix-uboot and i can now allocate all the memory in the system
with all peripherals enabled, and i just get killed by the OOM a some point.
But thanks for the help so far, even though it was not a kernel issue :-)
Med venlig hilsen/Best regards
Casper Mogensen

We should have v3.15 working fine, but PM features are not merged
in util for v3.16.
I would try dding calls to omap_sdrc_init to pdata-quirks.c
the same way board-over.c is doing:
omap_sdrc_init(mt46h32m32lf6_sdrc_params,
mt46h32m32lf6_sdrc_params);
If the memory timings are not correctly set by the bootloader
that could explain the issues.
Regards,
Tony
