Aaron, please visit CB:34805 patchset #6 comments and how you wish to address the alignment requirement about parameters passed to postcar_frame_setup_top_of_dram_usage(), if it will be extended to call set_var_mtrr().
Ya. I'm not sure we're in agreement on the best option forward there. Thanks for the pointer.
Subrata, can we have cbmem -t for this commit posted as well. My concern is that after all this work, POSTCAR_STAGE=y is still the better performing solution, winning POSTCAR_STAGE=n by some 7 ms.
I'm thinking that might be true as well. Anyway, we can have the discussion on that commit.
