HI Heinrich
I test on my Raspberry Pi Zero W
You can see raw log :

In GCC 9 support for the Armv5 and Armv5E architectures (which have no known implementations) has been removed, cf. https://gcc.gnu.org/gcc-9/changes.html
Commit 16540d07fd62 ("arm: fix -march for ARM11") changed the value of the compiler flag from -march=armv5 and -march=armv5t into -march=armv6 for ARM11.
The values prior to this patch were:
arch-$(CONFIG_CPU_ARM1136) =-march=armv5 arch-$(CONFIG_CPU_ARM1176) =-march=armv5tThe change lead to a regression with the Raspberry Pi Zero W not booting anymore.
Use -march=armv5t both for ARM1136 and ARM1176.

I do not possess an ARM1136 board for testing. It would be great, if anybody could test on real hardware.
