Subject: [PATCH] Fix include guards for older kernel/u-boot sources
|
||||
|
||||
Linux kernels before 4.17 and U-Boot versions before 2018.07 use libfdt
|
||||
include guards with leading underscores.
|
||||
|
||||
Those have been removed in dtc-1.4.7.
|
||||
|
||||
This patch handles both include guard types and allows the compilation
|
||||
of older Linux kernel and u-boot sources.
