Commit 41623c91 moved exception handling to arch/arm/lib/vectors.S, breaking CONFIG_USE_IRQ feature.
If CONFIG_USE_IRQ is enabled, undefined reference error occurs.
arch/arm/lib/built-in.o: In function `interrupt_init': arch/arm/lib/interrupts.c:37: undefined reference to `IRQ_STACK_START' arch/arm/lib/interrupts.c:37: undefined reference to `FIQ_STACK_START' make: *** [u-boot] Error 1
Because arch/arm/lib/vectors.S includes references to CONFIG_SYS_DV_NOR_BOOT_CFG and CONFIG_USE_IRQ, it must include <config.h>.
I routinely build all of ARM (32-bit) and AARCH64 (64-bit) targets and make sure all of them build properly, and concerning CONFIG_USE_IRQ, I even have a branch set to remove this option since a
git grep CONFIG_USE_IRQ | grep -vE \ '(#define|#ifdef|#ifndef|#if.*defined|#undef|#endif)'
shows that it is defined nowhere in our code.
Which source code are you using?
Out-of-tree board support code, maintained locally.
Then I'm afraid you'll have to keep this patch local too -- and note that I am considering overhauling, and possibly removing entirely, CONFIG_USE_IRQ (my grep command comes from my WIP on this).
You are not understanding at all what is the problem.
You changed the behaviour of three boards, "enbw_cmc", "da850evm_direct_nor", "calimain"! Probably they are broken.
These boards expects "0x00000011" (=CONFIG_SYS_DV_NOR_BOOT_CFG) at the beginning of the image. But since commit 41623c91, that is missing.
If you still don't understand, you should checkout 41623c91^ and 41623c91 and compare u-boot.dis.
