MIPS: Alchemy: Merge PB1100/1500 support into DB1000 code.

2012-10-11T09:11:20+00:00

The PB1100/1500 are similar to their DB-cousins but with a few
more devices on the bus.

This patch adds PB1100/1500 support to the existing DB1100/1500
code.

MIPS: Alchemy: merge PB1550 support into DB1550 code

2012-10-11T09:11:20+00:00

The PB1550 is more or less a DB1550 without the PCI IDE controller,
a more complicated (read: configurable) Flash setup and some other
minor changes.  Like the DB1550 it can be automatically detected by
reading the CPLD ID register bits.

This patch adds PB1550 detection and setup to the DB1550 code.

MIPS: Alchemy: Single kernel for DB1200/1300/1550

2012-10-11T09:11:20+00:00

Combine support for the DB1200/PB1200, DB1300 and DB1550 boards into
a single kernel image.

defconfig-generated image verified on DB1200, DB1300 and DB1550.

MIPS: MTX-1: Add udelay to mtx1_pci_idsel

2012-08-17T08:57:27+00:00

Without this udelay(1) PCI idsel does not work correctly on the
"singleboard" (T-Mobile Surfbox) for the MiniPCI device. The result is
that PCI configuration fails and the MiniPCI card is not detected
correctly. Instead of

PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [mem 0x40000000-0x4fffffff]
pci_bus 0000:00: root bus resource [io  0x1000-0xffff]
pci 0000:00:03.0: BAR 0: assigned [mem 0x40000000-0x4000ffff]
pci 0000:00:00.0: BAR 0: assigned [mem 0x40010000-0x40010fff]
pci 0000:00:00.1: BAR 0: assigned [mem 0x40011000-0x40011fff]

We see only the CardBus device:

PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [mem 0x40000000-0x4fffffff]
pci_bus 0000:00: root bus resource [io  0x1000-0xffff]
pci 0000:00:00.0: BAR 0: assigned [mem 0x40000000-0x40000fff]
pci 0000:00:00.1: BAR 0: assigned [mem 0x40001000-0x40001fff]

Later the device driver shows this error:

ath5k 0000:00:03.0: cannot remap PCI memory region
ath5k: probe of 0000:00:03.0 failed with error -5

I assume that the logic chip which usually supresses the signal to the CardBus
card has some settling time and without the delay it would still let the
Cardbus interfere with the response from the MiniPCI card.

What I cannot explain is why this behaviour shows up now and not in earlier
kernel versions before. Maybe older PCI code was slower?

MIPS: Alchemy: handle db1200 cpld ints as they come in

2012-07-23T12:53:38+00:00

Remove the loop in the cascade handler and instead unconditionally
handle just the first set interrupt coming from the CPLD.

This gets rid of a lot of spurious interrupts being triggered for
the SMSC91111 ethernet chip especially under high(er) IDE load:
"eth0: spurious interrupt (mask = 0xb3)"

Verified on DB1200 and DB1300.

MIPS: Alchemy: use 64MB RAM as minimum for devboards

2012-07-23T12:53:37+00:00

YAMON on all devboards provides the "memsize" envvar; in the unlikely
case that it can't be parsed just assume 64MB, which all boards have
at least.
