I am probably not the best person to answer the question, but see commit 3bf38548 (CBMEM: Tag chipsets with LATE_CBMEM_INIT) [1]: > In preparation to remove the static CBMEM allocator, tag the chipsets > that still do not implement get_top_of_ram() for romstage. So you need to implement that function for your chipset, remove the Kconfig selection, and if I remember correctly, everything else should then start working nicely. If I am not mistaken, Kyösti did a lot of the work during Google Summer of Code some years back. Maybe you find some information in the corresponding blog posts [2]. The next step is then to also add time-stamps to CBMEM, that you can read out with `cbmem -t`. > I just checked out the master from git in case they are part of the readings. Did you also test the latest code with your board? Could you please upload the *current* status to the board status repository [3]? Then it will also automatically be correctly tagged on the Wiki page *Supported Motherboards* [4].
