[PATCH 0/4] Use subdir-ccflags-* to inherit debug flag

[Yicong Yang]

Few drivers use ccflags-* in their top directory to enable
-DDEBUG, but don't have config options to enable debug
in the sub-directories. They should want the subdirectories
inherit the debug flag from the top.

Use subdir-ccflags-* instead of ccflags-* to inherit the debug
settings from Kconfig when traversing subdirectories.

We primarily find this issue when debugging PCIe and other
drivers may also have this issues. Previous discussion can
be find at
