The range check in the sprom image parser hex2sprom() is broken.
One sprom word is 4 hex characters.
This fixes the check and also adds much better sanity checks to the code.

The SPROM writing routines were broken since we rewrote the suspend

The current ssb irq setup in ssb_mipscore_init has the problem that it
configures some device on some irq without checking that the irq is not
taken by an other device.
For example in my case PCI host is on irq 0 and IPSEC on irq 3.
The current code:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host
But now IPSEC irq is not routed anymore to the mips code and dev->irq is
wrong. This causes a problem described in [1].
This patch tries to solve the problem by making set_irq configure the
device we want to take the irq on the shared irq0. The previous example
becomes:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host:
- irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
I also added some code to print the irq configuration after irq setup to
allow easier debugging. And I add extra checking in ssb_mips_irq to report
device without irq or device with not routed irq.

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

however, all of the extraction routines extract pseudo data for these

The current code checks for the special signature that signifies
a revision 4 SPROM. Now that a rev. 8 SPROM with a 440-byte length
has been found that may not have any special code, this check could
be relaxed. With this patch, if the CRC is incorrect for a 256-byte
SPROM, the code will immediately check for a 440-byte SPROM. If there
is still a CRC error, the size is set to 440 bytes, which allows dumping
of most of any 512-byte SPROM if one is encountered.
