23 address from DTS, in which case RAM will be identity-mapped. Some
24 architectures may require RAM to be mapped in this way; they may have
25 just one RAM region and doing this makes linking much simpler, as
26 at least when the kernel boots all virtual RAM addresses are the same
30 Otherwise, if RAM isn't identity-mapped:
35 the kernel's address space, such as not overlapping physical RAM
36 regions if RAM is not identity-mapped, or the virtual and physical
50 if this is not the same offset from the beginning of RAM.
74 for mapping driver MMIO regions, as well as special RAM mapping use-cases
81 RAM size larger than the defined bounds of the virtual address space.
