- Linux kernel booting: Look at the doc in the Kernel source :
- Documentation/arm64/booting.txt
- The kernel image must be placed at the start of the memory to be used by the
- kernel (2MB aligned) + 0x80000.
-
- The Device tree blob is expected to be under 2MB and be within the first 512MB
- of kernel memory and be 2MB aligned.
-
- A Flattened Device Tree (FDT) used to boot linux needs to be updated before
- the kernel is started. It needs to indicate how secondary cores are brought up
- and where they are waiting before loading Linux. The FDT also needs to hold
- the correct kernel command line and filesystem RAM-disk information.
- At the moment we do not fully support generating this FDT information at
- runtime. A prepared FDT should be provided at boot. FDT is the only supported
- method for booting the AArch64 Linux kernel.
-
- Linux does not use any runtime services at this time, so we can let it
- overwrite UEFI.
