2024-12-20common: memtop: Fix the return type for find_ram_topVenkatesh Yadav Abbarapu
As the return type is "int" for find_ram_top() function and returning the "base" which is of phys_addr_t is breaking when the "base" address is 64-bit. So fix this by updating the return type as phys_addr_t.

2024-11-15common: memtop: add logic to detect ram_topSughosh Ganu
Add generic logic to determine the ram_top value for boards. Earlier, this was achieved in an indirect manner through a set of LMB API's. That has since changed so that the LMB code is available only after relocation. Replace those LMB calls with a single call to get_mem_top() to determine the value of ram_top.
