Inconsistent reset address

[NignetShark]

Bug Description

I noticed that reset address was moved from boot_addr + 0x80 to boot_addr + 0x0 but some files are still using the old address, such as :

• sw/simple_system/common/ctr0.S, line 100 :

// reset vector
.org 0x80
jal x0, reset_handler

• sw/simple_system/common/link.ld, line 22 :

_entry_point = _vectors_start + 0x80;

I don't know if it's a legacy from the Ibex documentation but doc/03_reference/exception_interrupts.rst and doc/02_user/integration.rst still refer to the old reset address which might be misleading.

hello @NignetShark , it's definitively legacy code, not sure yet what the cve2 team will do with those SW files, if removing them or fixing @christian-herber-nxp

Decision is that reset address will be 0. this should be fixed in the files pointed out.

I have no way to test the requested modification of the crt0.S as the current test environment is using bare-metal-programs using the bsp/crt0.S.
