Hello, Here are a couple of cleanups and a very basic memory controller model providing a configuration register. This is needed to determine the RAM size of the SOC, only used by U-Boot as of today.
Ultimately, we would want to add more support for U-Boot and be able to boot from flash 0 but the device model of the m25p80 object is not designed to use a memory region. And so, it is difficult to define a rom device for the flash backend. Some initial patches were proposed but they are not being friendly with the object interface. Work in progress. Thanks, C.
