Accessing nor when booting from nand

Hi,
I would like to know if the NOR flash is accessible when booting from NAND.
In other words, if I boot linux from NAND, is there a way to access the NOR
flash ?
When booting from NOR, the flash is accessible in nGCS0. Is it accessible
in another nGCS* ?
Thanks,
Cyprien

Yes. NOR and NAND using different access methods, so there is no problem to
still access the NOR if you boot from NAND and vice versa.

From what I've seen NOR is only connected using nGCS0, which seems disabled
(remapping stepping stone) when booting from NAND.
Do you know how to get back normal nGCS0 mapping ?
