Change the ppc440_sdram model to a QOM class derived from the

modelling the DDR2 SDRAM controller found in the 460EX (used on the

may have this controller but we only emulate enough of it for the

modelling the DDR SDRAM controller found in the 440EP (used on the

controllers on some 405 SoCs so we also use it for those now. This
likely does not cause problems for guests we run as the new features
are just not accessed but to model 405 SoC accurately some features
may have to be disabled or the model split between 440 and older.
Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an
updated DDR2 SDRAM controller implemented by the ppc440_sdram model
(only partially, enough for the 460EX on the sam460ex) that is not yet

To boot S-mode firmware payload like EDK2 from persistent
flash storage, qemu needs to pass the flash address as the
next_addr in fw_dynamic_info to the opensbi.
When both -kernel and -pflash options are provided in command line,
the kernel (and initrd if -initrd) will be copied to fw_cfg table.
The S-mode FW will load the kernel/initrd from fw_cfg table.
If only pflash is given but not -kernel, then it is the job of
of the S-mode firmware to locate and load the kernel.
In either case, update the kernel_entry with the flash address
so that the opensbi can jump to the entry point of the S-mode
firmware.
