It actually contains lots of sub-modules like various PLLs to control different peripherals. Only the mininum capabilities are emulated to make the HSS DDR memory initialization codes happy. Lots of sub-modules are created as an unimplemented devices.

Address 0xC000_0000 and above is aliased to the same 1 GiB low memory with different cache attributes. At present QEMU maps the system memory contiguously from 0x8000_0000. This corrects the wrong QEMU logic. Note address 0x14_0000_0000 is the alias to the high memory, and even physical memory is only 1 GiB, the HSS codes still tries to probe the high memory alias address. It seems there is no issue on the real hardware, so we will have to take that into the consideration in our emulation. Due to this, we we increase the default system memory size to 2 GiB so that user gets notified an error when less than 2 GiB is specified.

The device tree file includes the description for the I2C1 node hence kernel tries to probe the I2C1 device during boot. It is enough to create an unimplemented device for I2C1 to allow the kernel to continue booting to the shell.
