 -  the usb option was absent and both set_defaults and the machine

PPC: e500 pci host: Add support for ATMUs

The e500 PCI controller has configurable windows that allow a guest OS
to selectively map parts of the PCI bus space to CPU address space and
to selectively map parts of the CPU address space for DMA requests into
PCI visible address ranges.

So far, we've simply assumed that this mapping is 1:1 and ignored it.

However, the PCICSRBAR (CCSR mapped in PCI bus space) always has to live
inside the first 32bits of address space. This means if we always treat
all mappings as 1:1, this map will collide with our RAM map from the CPU's
point of view.

So this patch adds proper ATMU support which allows us to keep the PCICSRBAR
below 32bits local to the PCI bus and have another, different window to PCI
BARs at the upper end of address space. We leverage this on e500plat though,
mpc8544ds stays virtually 1:1 like it was before, but now also goes via ATMU.

With this patch, I can run guests with lots of RAM and not coincidently access

PPC: e500: Move CCSR and MMIO space to upper end of address space

On e500 we're basically guaranteed to have 36bits of physical address space
available for our enjoyment. Older chips (like the mpc8544) only had 32bits,
but everything from e500v2 onwards bumped it up.

It's reasonably safe to assume that if you're using the PV machine, your guest
kernel is configured to support 36bit physical address space. So in order to
support more guest RAM, we can move CCSR and other MMIO windows right below the
end of our 36bit address space, just like later SoC versions of e500 do.

With this patch, I'm able to successfully spawn an e500 VM with -m 48G.

ppc/mac_oldworld.c, sparc/sun4m.c); we can easily add it to the "virt"
board.

Because MMIO access is slow on ARM KVM, we enable the guest, with
fw_cfg_init_mem_wide(), to transfer up to 8 bytes with a single access.
This has been measured to speed up transfers up to 7.5-fold, relative to
single byte data access, on both ARM KVM and x86_64 TCG.

The MMIO register block of fw_cfg is advertized in the device tree. As
base address we pick 0x09020000, which conforms to the comment preceding
"a15memmap": it falls in the miscellaneous device I/O range 128MB..256MB,
and it is aligned at 64KB. The DTB properties follow the documentation in
the Linux source file "Documentation/devicetree/bindings/arm/fw-cfg.txt".

fw_cfg automatically exports a number of files to the guest; for example,
"bootorder" (see fw_cfg_machine_reset()).

The behavior of the (big endian) multi-byte data reads is best shown

>>> readl 0x9020000
<<< OK 0x000000004600cb32

Remember this is big endian.  On big endian machines, it is stored
directly as 0x46 0x00 0xcb 0x32.

On a little endian machine, we have to first swap it, so that it becomes
0x32cb0046.  When written to memory, it becomes 0x46 0x00 0xcb 0x32
again.

Reading byte-by-byte works too, of course:

>>> readb 0x9020000
<<< OK 0x0000000000000038
>>> readb 0x9020000
<<< OK 0x00000000000000ec

Here only a single byte is read at a time, so they are read in order
similar to the 1-byte data port that is already in PPC and SPARC
machines.

9 years agofw_cfg: hard separation between the MMIO and I/O port mappings

fw_cfg: hard separation between the MMIO and I/O port mappings

We are going to introduce a wide data register for fw_cfg, but only for
the MMIO mapped device. The wide data register will also require the
tightening of endiannesses.

However we don't want to touch the I/O port mapped fw_cfg device at all.

Currently QEMU provides a single fw_cfg device type that can handle both
I/O port and MMIO mapping. This flexibility is not actually exploited by
any board in the tree, but it renders restricting the above changes to
MMIO very hard.

Therefore, let's derive two classes from TYPE_FW_CFG: TYPE_FW_CFG_IO and
TYPE_FW_CFG_MEM.

TYPE_FW_CFG_IO incorporates the base I/O port and the related combined
MemoryRegion. (NB: all boards in the tree that use the I/O port mapped
flavor opt for the combined mapping; that is, when the data port overlays
the high address byte of the selector port. Therefore we can drop the
capability to map those I/O ports separately.)

TYPE_FW_CFG_MEM incorporates the base addresses for the MMIO selector and
data registers, and their respective MemoryRegions.

The "realize" and "props" class members are specific to each new derived
class, and become unused for the base class. The base class retains the
"reset" member and the "vmsd" member, because the reset functionality and
the set of migrated data are not specific to the mapping.

The new functions fw_cfg_init_io() and fw_cfg_init_mem() expose the
possible mappings in separation. For now fw_cfg_init() is retained as a
compatibility shim that enforces the above assumptions.

This commit changes the integratorcp and versatilepb CPU initialization from
using the generic ARM cpu_arm_init function to doing it inline.  This is
necessary in order to allow CPU configuration changes to occur between CPU
