block: rename buffer_alignment to guest_block_size

The alignment field is now set to the value that is promised to the
guest, rather than required by the host. The next patches will make
QEMU aware of the host-provided values, so make this clear.

The alignment is also not about memory buffers, but about the sectors on...

isa: Clean up use of cannot_instantiate_with_device_add_yet

Drop it when there's no obvious reason why device_add could not work.
Else keep and document why.

  • isa-fdc: drop
  • i8042: drop, even though its I/O base is hardcoded (because you
    could conceivably still add one to a board that has none), and even...

qdev: Replace no_user by cannot_instantiate_with_device_add_yet

In an ideal world, machines can be built by wiring devices together
with configuration, not code. Unfortunately, that's not the world we
live in right now. We still have quite a few devices that need to be...

Add max device width parameter for NOR devices

For handling CFI and device ID reads, we need to not only know the
width that a NOR flash device is configured for, but also its maximum
width. The maximum width addressing mode is used for multi-width
parts no matter which width they are configured for. The most common...

Fix CFI query responses for NOR flash

This change fixes the CFI query responses to handle NOR device
widths that are different from the bank width. Support is also
added for multi-width devices in a x8 configuration. This is
typically x8/x16 devices, but the CFI specification mentions...

Fix NOR flash device ID reading

Fix NOR flash manufacturer and device ID reading. This now
properly takes into account device widths and device max widths
as required. The reading of these IDs uses the same max_width
dependent addressing as CFI queries....

return status for each NOR flash device

Now that we know how wide each flash device that makes up the bank is,
return status for each device in the bank. Leave existing code
that treats 32 bit wide banks as composed of two 16 bit devices as otherwise
we may break configurations that do not set the device_width propery....
