Wireless Broadcom chips can have either their SPROM data stored
on either external SPROM or on-chip OTP memory. Both are accessed
through the same register space. This patch adds support for the
on-chip OTP memory.Tested with:
BCM43224 OTP and SPROM
BCM4331 SPROM
BCM4313 OTPThis patch is in response to linux-wireless thread [1].

When not SPROM is available a fallback mechanism is used. However,
when that fails the code currently continues. This patch assures
that the bcma_sprom_get() function aborts when that happens.Cc: Rafal Milecki

On SoCs the sprom is stored in the nvram in a special partition on the
flash chip. The nvram contains the sprom for the main bus, but
sometimes also for a pci devices using bcma. This patch makes it
possible for the arch code to register a function to fetch the needed
sprom from the nvram and provide it to the bcma code.Signed-off-by: Hauke Mehrtens

This check is needed on the BCM43224 device as it says in the
capabilities it has an sprom but is extra check says it has not.Signed-off-by: Hauke Mehrtens

The SPROM location has been relocated again for some devices. This patch
will log the offset when CONFIG_BCMA_DEBUG has been selected.Signed-off-by: Larry Finger

We need to disable ext. PA lines for reading SPROM. It's disabled by
default, but this patch allows using bcma after loading wl, which leaves
workaround enabled.Cc: Arend van Spriel

Some cards do not use additional 0x30 offset for SPROM location. We do
not know the real condition for it yet, make it BCM4331 specific for
now.Signed-off-by: Rafał Miłecki

SPROM rev 9 was discovered on 14e4:4331, it seems to have very similar
layout to rev 8 one. Use the same extracting function until we find some
differences.Signed-off-by: Rafał Miłecki

The SoCs like the bcm4716 do not have a sprom on the bcma bus like a
pcie device. It stores the values in some partition on flash memory.
For ssb this informations are read out in the bcm47xx arch code,
something like that should also be implemented for bcma. Without this
patch bcma panics on SoCs.Signed-off-by: Hauke Mehrtens

In case of BCMA cards SPROM is located in the ChipCommon core, it is
not mapped as separated host window. So far we have met only SPROMs rev
8.
SPROM layout seems to be the same as for SSB buses, so we decided to
share SPROM struct and some defines.
For now we extract MAC address only, this can be improved of course.Signed-off-by: Rafał Miłecki
