/* Linker script to configure memory regions.
geeksville: modified this to simulate a nrf52832 but with a sd140 soft device. So I can
see how the memory footprint works on this lower end CPU. Note: to work with sd140 in my bootloader
I need to start ram at 0x6000 (instead of the correct 0x3600 for sd132) - so I have less
RAM available than on a real 832.
