    xtensa: cleanup MMU setup and kernel layout macros · a9f2fc62
    Max Filippov authored
    Make kernel load address explicit, independent of the selected MMU
    configuration and configurable from Kconfig. Do not restrict it to the
    first 512MB of the physical address space.
    
    Cleanup kernel memory layout macros:
    
    - rename VECBASE_RESET_VADDR to VECBASE_VADDR, XC_VADDR to VECTOR_VADDR;
    - drop VIRTUAL_MEMORY_ADDRESS and LOAD_MEMORY_ADDRESS;
    - introduce PHYS_OFFSET and use it in __va and __pa definitions;
    - synchronize MMU/noMMU vectors, drop unused NMI vector;
    - replace hardcoded vectors offset of 0x3000 with Kconfig symbol.
