Hi lists, As I have moved forward to writing the ramstage, much more problems came out. PCI devices are just extra devices that can be used but not key devices like those on X86. Most devices on ARM are connected through AHBA bus and can be configured by reading and writing data from and into the control registers. So we need a new way to record the information of hardware instead of depending on the enumerate and init functions of PCI devices. This is hard for me since the format we are using to record information is highly depending on PCI bus. We need to design a new format for ARM.
Could anyone help me? Any suggestions are very welcome!
Are you thinking of extending the resource allocator? How does uboot do this? What would your device tree look like?
