How to access sail's memory.

[animesh211]

Hi.
While trying to access a memory like 'f0000000' in the setup for atomics, I am seeing Exceptions being taken from sail model.
Seeing exceptions like these-

within_phys_mem: 0xF0000000 not within phys-mem:
plat_rom_base: 0x00001000
plat_rom_size: 0x00001000
plat_ram_base: 0x80000000
plat_ram_size: 0x04000000
trapping from M to M to handle store/amo-access-fault
handling exc#0x07 at priv M with tval 0xF0000000
CSR mstatus <- 0x00001800

How can I access this memory region?
