Enabling CONFIG_ISR_TABLES_LOCAL_DECLARATION for nrf54l15 flpr CPU outputs non-working image #97846
Description
Describe the bug
This option can be selected, indicating that it should be supported, but seemingly it does not appear to be. Partial output of map file with this Kconfig disabled (this is being tested with the hello_world sample application, the vpr_launcher image is included to allow it to boot):

I'm not a RISCV architectural person but to me the __start vector looks to be placed at a wholly garbage address for some reason when it should be right at the start?
Regression
- This is a regression.
Steps to reproduce
Build hello_world for nrf54l15dk/nrf54l15/cpuflpr with CONFIG_ISR_TABLES_LOCAL_DECLARATION enabled
Relevant log output
Impact
Major – Severely degrades functionality; workaround is difficult or unavailable.
