From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Peter Robinson Date: Thu, 20 Jun 2019 16:21:48 +0100 Subject: [PATCH] linux, efi, arm*, fdt: break FDT extra allocation space out into a #define A certain amount of dynamic space is required for the handover from GRUB/Linux-EFI-stub. This entails things like initrd addresses, address-cells entries and associated strings. But move this into a proper centralised #define rather than live-code it in the loader.
