    armv8: layerscape: Rewrite memory reservation · 36cc0de0
    York Sun authored
    
    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.
    The same region is reserved for efi_loader.
