Using Storage with the W25 flash chips

Ah, looks like it's like this on the RAK5010

# Use this for the 8mb external flash if chip is installed in board
#    'address' : 0x60000000, # put this in external spiflash (see below)
#    'page_size' : 4096,
#    'pages' : 2048, # Entire 8MB of external flash
#    'flash_available' : 512 - ((31 + 8 + 2)*4) # Softdevice uses 31 pages of flash, bootloader 8, FS 2. Each page is 4 kb.
  },
};

devices = {
  'LED1' : { 'pin' : 'D12' },
  # IS25WP064A QSPI flash
#  'SPIFLASH' : { # Chip is not installed in board
#            'pin_cs' : 'D42',  #  cs    P1.10
#            'pin_sck' : 'D43', #  clk   P1.11
#            'pin_mosi' : 'D3', #  d0    P0.03
#            'pin_miso' : 'D47', #  d1    P1.15
#            'pin_wp' : 'D46', #  d2    P1.14 
#            'pin_rst' : 'D45', #  d3    P1.13
#            'size' : 8192*1024, # 8MB
#            'memmap_base' : 0x60000000 # map into the address space (in software)
#          }
};

which I expect the commented out lines would relocate the storage to external flash
