We need to do a few things differently if we are to support a virtual memory map, i.e. CONFIG_MMU where CONFIG_KERNEL_VM_BASE is not the same as CONFIG_SRAM_BASE_ADDRESS. - All sections must be specified with a VMA and LMA, where VMA is the virtual address and LMA is the physical memory location. - All sections must be specified with ALIGN_WITH_INPUT to keep VMAs and LMAs synchronized To do this, the existing linker macros need some adjustment: - GROUP_LINK_IN undefined when CONFIG_KERNEL_VM_BASE is not the same as CONFIG_SRAM_BASE_ADDRESS. - New macro GROUP_ROM_LINK_IN for text/rodata sections - New macro GROUP_NOLOAD_LINK_IN for bss/noinit sections - Implicit ALIGN_WITH_INPUT for all sections GROUP_FOLLOWS_AT is unused anywhere in the kernel for years now and has been removed.
