m68k/irq - Use polled IRQ flag for MFP timer cascaded interrupts

2014-01-13T08:29:10+00:00

Some Atari hardware has no capacity to raise interrupts (e.g.
network or USB adapter hardware attached via ROM port). The driver
interrupt routine is called from a timer interrupt (timer D) in
these cases, using chained device specific pseudo interrupts
(IRQ_MFP_TIMER1 ff.)

These interrupts will more often than not, return IRQ_NONE as
there is not always work for the device handler when called.
Too many unhandled interrupts will result in the interrupt
being disabled by the stuck interrupt watchdog.

As preferred option to flag interrupts as needing exclusion
from the watchdog mechanism, tglx added the IRQ_IS_POLLED flag
for use in such a case. Currently, two interrupts need to use
this flag. Add more users as needed.

m68k/amiga,atari: Fix specifying multiple debug= parameters

2013-12-08T10:03:21+00:00

Since commit d6713b4091a99fa2af2fabdcd2f3fb97f32ecf2e ("m68k: early
parameter support"), the user can specify multiple debug consoles using the
"debug=" kernel command line parameter.
However, as there's only a single struct console object, which is reused,
it would actually register the same console object multiple times, causing
the following warning:

WARNING: CPU: 0 PID: 0 at kernel/printk/printk.c:2233 register_console+0x36/
console 'debug0' already registered

Make sure to register the console object only once, to avoid the warning.

Note that still only one console (the one corresponding to the last
"debug=" parameter) will be active at the same time, as the .write() method
of the already registered console object is overwritten by a subsequent
"debug=" parameter.

m68k/UAPI: Disintegrate arch/m68k/include/asm/bootinfo.h

Export the bootinfo definitions that are used by bootstrap loaders, and
split them up in generic and platform-specific parts.

m68k/atari: USB - add platform devices for EtherNAT/NetUSBee ISP1160 HCD

2013-04-16T19:35:41+00:00

Add platform devices used by the isp116x-hcd driver for EtherNAT and
NetUSBee. Note that the NetUSBee also contains a RTL8019 Ethernet chip,
so its platform device is used to cover the EtherNEC case, too.
Register definitions thanks to David Galvez

m68k/atari: EtherNAT - add interrupt chip definition for CPLD interrupts

2013-04-16T19:35:39+00:00

Add a dedicated interrupt chip definition for the EtherNAT CPLD interrupts.
SMC91C111 and ISP1160 chips have separate interrupts that can be enabled
and disabled in a CPLD register at offset 0x23 from the card base.

Note the CPLD interrupt control register is mapped on demand, whenever any
interrupt enable/disable action is requested. The EtherNAT USB driver still
needs interrupts disabled around reset and start actions.
In particular, we cannot entirely rely on the irq_startup being called
first.

The smc91x and isp116x-hcd drivers will use this feature.

m68k/atari: EtherNEC - add platform device support

2013-04-16T19:20:14+00:00

Add platform device for the Atari ROM port ethernet adapter, EtherNEC.
This platform device will be used by the ne.c driver.

m68k/atari: EtherNAT - platform device and IRQ support code

2013-04-16T19:18:29+00:00

Add platform device and interrupt definitions necessary for the EtherNAT
Ethernet/USB adapter for the Falcon extension port. EtherNAT interrupt
numbers are 139/140 so the max. interrupt number for Atari has to be
increased.
