This is an interesting one!
It happens when CONFIG_DEBUG_LL_INCLUDE does not have a custom debug header for the platform under arch/arm/include/debug and the KConfig falls through to the default value, which is <mach/debug-macro.S>.
Only that the majority is not using <mach/*> anymore.
I feel a bit like setting the default to debug/8250.S or something.
Suggestions?
Then the actual bug exposed:
The config tested by the robot is using CONFIG_ARCH_AT91=y CONFIG_SOC_SAMV7=y
When I look into Kconfig.debug it seems that this will define DEBUG_AT91_SAMV7_USART1 but only a physical address, no virtual address and and actually no debug header. It seems LL_DEBUG is broken on SAMV7 and never really worked so now that crops up.
Nicolas, something that should be fixed, I think?
Yours, Linus Walleij
