PPC: e500: Map PIO space into core memory region

On PPC, we don't have PIO. So usually PIO space behind a PCI bridge is
accessible via MMIO. Do this mapping explicitly by mapping the PIO space
of our PCI bus into a memory region that lives in memory space....

pseries: Implement qemu initiated shutdowns using EPOW events

At present, using 'system_powerdown' from the monitor or otherwise
instructing qemu to (cleanly) shut down a pseries guest will not work,
because we did not have a method of signalling the shutdown request to the...

Rename target_phys_addr_t to hwaddr

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,...

serial: split serial.c

Split serial.c into serial.c, serial.h and serial-isa.c. While being at
creating a serial.h header file move the serial prototypes from pc.h to
the new serial.h. The latter leads to s/pc.h/serial.h/ in tons of
boards which just want the serial bits from pc.h...

create struct for machine initialization arguments

This should help us to:
- More easily add or remove machine initialization arguments without
having to change every single machine init function;
- More easily make mechanical changes involving the machine init...

fdt: move dumpdtb interpretation code to device_tree.c

The dumpdtb code can be useful in more places than just for e500. Move it
to a generic place.

PPC: e500: increase DTC_LOAD_PAD

An allowance of 5 MiB for BSS is not enough for Linux kernels with certain
debug options enabled (not sure exactly which one caused it, but I'd guess
lockdep). The kernel I ran into this with had a BSS of around 6.4 MB.

PPC: e500: calculate initrd_base like dt_base

While investigating dtb pad issues, I noticed that initrd_base wasn't taking
loadaddr into account the way dt_base was. This seems wrong.

PPC: e500: Only expose even TLB sizes in initial TLB

When booting our e500 machine, we automatically generate a big TLB entry
in TLB1 that covers all of the code we need to run in there until the guest
can handle its TLB on its own.

However, e500v2 can only handle MAS1.0 sizes. However, we keep our TLB...
