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.
