So previously the PSW mask was zero and hence we had 24-bit addressing, no? Now, we have bits 31 and 32 one and hence 64 bit addressing.
Yes
Also the linker script patch will exchange the mask for an invalid one
so we need to replace both the mask and the address.
I guess 24-bit addressing is not appropriate here (or at least doesn't matter too much), so I guess this is intended, isn't it?
Claudio complained about the addressing change so I moved it over to
full 64 bit.
