For ARMv8 Layerscape SoCs, secure memory and MC memorey are reserved at the end of DDR. DDR is spit into two or three banks. This patch reverts commit aabd7ddb and simplifies the calculation of reserved memory, and moves the code into common SoC file. Secure memory is carved out first. DDR bank size is reduced. Reserved memory is then allocated on the top of available memory. U-Boot still has access to reserved memory as data transferring is needed. Device tree is fixed with reduced memory size to hide the reserved memory from OS.
I haven't looked in detail, but could you please ensure that you also reserve those regions in the efi_loader memory map?
I missed efi reserved memory map. Will add in v2 patch.
Alex,
Is the misc_init_r() the best place to add such reservation under your code dealing with DP_DDR? It is per board code. As of now, we only have ls2080ardb with efi boot.
