pci: Add general support for execution of video ROMs

Some platforms don't have native code for dealing with their video
hardware. In some cases they use a binary blob to set it up and perform
required actions like setting the video mode. This approach is a hangover
from the old PC days where a ROM was provided and executed during startup.

Even now, these ROMs are supplied as a way to set up video. It avoids the
code for every video chip needing to be provided in the boot loader. But
it makes the video much less flexible - e.g. it is not possible to do
anything else while the video init is happening (including waiting hundreds
of milliseconds for display panels to start up).

pci: Abort early if bus does not exist

When listing the devices on a PCI bus, the current code will blindly try
to access all devices. Internally this causes pci_bus_to_hose() to be
repeatedly called and output an error message every time. Prevent this
by calling pci_bus_to_hose() once and abort early if no bus was found.

vsprintf: Add modifier for phys_addr_t

Provide a new modifier to vsprintf() to print phys_addr_t variables to
avoid having to cast or #ifdef when printing them out. The %pa modifier
is used for this purpose, so phys_addr_t variables need to be passed by
reference, like so:

phys_addr_t start = 0;

printf("start: %pa\n", &start);

Depending on the size of phys_addr_t this will print out the address
with 8 or 16 hexadecimal digits following a 0x prefix.

9 years agofs: make it possible to read the filesystem UUID

fs: make it possible to read the filesystem UUID

Some filesystems have a UUID stored in its superblock. To
allow using root=UUID=... for the kernel command line we
need a way to read-out the filesystem UUID.

changes rfc -> v1:
 - make the environment variable an option parameter. If not
   given, the UUID is printed out. If given, it is stored in the env
   variable.
 - corrected typos
 - return error codes

changes v1 -> v2:
 - fix return code of do_fs_uuid(..)
 - document do_fs_uuid(..)
 - implement fs_uuid_unsuported(..) be more consistent with the
   way other optional functionality works

changes v2 -> v3:
 - change ext4fs_uuid(..) to make use of #if .. #else .. #endif

spl: Change debug to printf for "Unsupported boot-device"

We had the problem on an AM33xx platform, that SPL detected an
unsupported boot-device. But since this message is a debug message
it took a bit of time to really know, where the hangup in SPL
resulted from. So let's change this debug message to a printf
and also print the detected boot-device that is not supported.
This makes debugging of such cases much easier.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
