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?

This is what the platforms without an MMU are doing. I don't think there
is anything platform specific to fix.

I confirm DEBUG_LL is not broken on SAMV7. The config used by lkp doen't
define DEBUG_AT91_SAMV7_USART1, it is not the culprit. Select it and the
problem is gone since DEBUG_AT91_SAMV7_USART1 selects DEBUG_AT91_UART
and DEBUG_LL_INCLUDE has:
default "debug/at91.S" if DEBUG_AT91_UART
Your issue is CONFIG_DEBUG_SEMIHOSTING

The last mach/debug-macro.S file was apparently removed in 2015,
in commit 0045c0dd2f64 ("ARM: debug-ll: rework footbridge handling").

Right, in particular, semihosting is not handled in
arch/arm/boot/compressed/head.S the way it is handled in
arch/arm/boot/compressed/debug.S, arch/arm/kernel/debug.S
and arch/arm/kernel/head.S.
I wonder if we should move the semihosting code into a separate
arch/arm/include/debug/semihosting.S to make the generic
code treat it the same as all the other options.
Alternatively, disabling CONFIG_DEBUG_UNCOMPRESS
when SEMIHOSTING is set would be the cheapest workaround
for the particular build failure.
