bcma: fill core details for every device

2014-10-27T18:16:13+00:00

We were setting things like dma_dev, IRQ, etc. during core registration
only. We need such info for cores handled internally (e.g. ChipCommon)
as well.

bcma: print chip ID in a more user-friendly form

2014-09-26T21:06:50+00:00

Some chip IDs are easier to read/understand when printed in a decimal
form. For example on my bcm53xx arch router this patch replaces:
Found chip with id 0xCF12, rev 0x00 and package 0x02
with a:
Found chip with id 53010, rev 0x00 and package 0x02

bcma: add support for chipcommon B core

2014-09-09T19:33:05+00:00

This core is used on BCM4708 to configure the PCIe and USB3 PHYs and it
contains the addresses to the Device Management unit. This will be used
by the PCIe driver first.

bcma: store more alternative addresses

2014-09-09T19:33:05+00:00

Each core could have more than one alternative address. There are cores
with 8 alternative addresses for different functions. The PHY control
in the Chip common B core is done through the 2. alternative address
and not the first one.

bcma: move bus struct setup into early part of host specific code

2014-09-09T19:27:18+00:00

This change is important for SoC host. In future we will want to know
chip ID (needed for early MIPS boot) before doing cores scanning.

bcma: only map wrapper if its address is available

2014-08-28T18:41:56+00:00

The Chipcommon B core does not have a wrap address and it would fail here.

bcma: use NS prefix for names of Northstar specific cores

2014-07-31T17:45:32+00:00

It's cleaner and we don't have quite identical names like
BCMA_CORE_PCIEG2 and BCMA_CORE_PCIE2.

bcma: fix error code handling on 64 Bit systems

2013-09-09T18:44:33+00:00

On most 64 Bit systems unsigned long is 64 bit long and then -MAX_ERRNO
is out of the range of a u32 used to store the error code in.
This patch casts the -MAX_ERRNO to a u32 instead.

This fixes a regression introduced in:

bcma: fix handling of big addrl

2013-07-22T20:54:40+00:00

The return value of bcma_erom_get_addr_desc() is a unsigned value and it
could wrap around in the two complement writing. This happens for one
core in the BCM4708 SoC.
