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.
