On aarch64 physBase is the constant that points to the bottom of physical memory (RAM). Prior to this change the kernel window was mapped directly to physBase, which is usually not a 0 paddr. As a consequence the kernel could not access any memory below physBase. This change fixes this issue by mapping the start of the kernel window to 0 in the physical address space. - add new constant PADDR_LOAD, the location of the kernel image in the physical address space. - add new constant PADDR_BASE, the start of the physical address space (0). - add new constant KERNEL_ELF_BASE, the location of the kernel image in kernel virtual memory. A consequence of this change is that on aarch64, the kernelBase constant now points to the start of the kernel window in virtual memory, but *not* to the start of the kernel image as these are now different. |
