isa_get_irq() asks for an ISADevice which piix-ide doesn't provide.
Passing a NULL pointer works but causes the isabus global to be used

The block layer APIs use BdrvRequestFlags while qemu-io code uses int.

Images can't be opened in coroutine context because opening needs to
change the block graph. Add no_co_wrappers so that coroutines have a
simple way of opening images in a BH instead.
At the same time, mark the wrapped functions as no_coroutine_fn.

Some functions must not be called from coroutine context. The common
pattern to use them anyway from a coroutine is running them in a BH and
letting the calling coroutine yield to be woken up when the BH is
completed.
Instead of manually writing such wrappers, add support for generating
them to bl

bdrv_open*() must not be called from coroutine context, amongst others
because it modifies the block graph. However, some functions - in
particular all .bdrv_co_create* implementations of image formats - do
call it from coroutine context. This is already wrong today, but when we
add locking, it act

Hi Cedric,
Good suggestion but we will not be able to share those EEPROM image files yet.
We are trying to figure out how to sanitize them.
For eeprom tests, they could contain any data with some well know pattern
to check. It could/should be generated.
