* [MIPS] Remove CONFIG_SIBYTE_PT{1120,1125,SWARM}Ralf Baechle2008-01-291-3/+0
| | | | | | | | According to Broadcom the PT systems are production test systems which never reached customers so no need to keep the fragmentary support we currently have. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] Sibyte: Delete {sb1250,bcm1480}_steal_irq().Ralf Baechle2007-10-294-54/+0
| | | | | | | | | They break the timer interrupt initialization and only seem to be a kludge for initialization happening in the wrong order. Further testing done by Thiemo confirms the suspicion that the other invocations also seem to have useless. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] time: SMP-proofing of Sibyte clockevent/clocksource code.Ralf Baechle2007-10-226-165/+158
| | | | | | | | | | | The BCM148 has 4 cores but there are also just 4 generic timers available so use the ZBbus cycle counter instead of it. In addition the ZBbus counter also offers a much higher resolution and 64-bit counting so I'm considering a later complete conversion to it once I figure out if all members of the Sibyte SOC family support it - the docs seem to agree but the headers files seem to disagree ...

* [MIPS] Switch from to_tm to rtc_time_to_tmRalf Baechle2007-10-112-2/+4
| | | | | | | | | This replaces the MIPS-specific to_tm function with the generic rtc_time_to_tm function. The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up.

* sb1250-duart.c: SB1250 DUART serial supportMaciej W. Rozycki2007-07-172-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a driver for the SB1250 DUART, a dual serial port implementation included in the Broadcom family of SOCs descending from the SiByte SB1250 MIPS64 chip multiprocessor. It is a new implementation replacing the old-fashioned driver currently present in the linux-mips.org tree. It supports all the usual features one would expect from a(n asynchronous) serial driver, including modem line control (as far as hardware supports it -- there is edge detection logic missing from the DCD and RI lines and the driver does not implement polling of these lines at the moment), the serial console, BREAK transmission and reception, including the magic SysRq. The receive FIFO threshold is not maintained though. The driver was tested with a SWARM board which uses a BCM1250 SOC (which is dual MIPS64 CMP) and has both ports of the single DUART implemented wired externally. Both were tested. Testing included using the ports as terminal lines at 1200bps (which is the ports minimum), 115200bps and a couple of random speeds inbetween. The modem lines were verified to operate correctly. No testing was performed with a use as a network interface, like with SLIP or PPP. Signed-off-by: Maciej W.

| | | | | | | | | | Many Makefiles in arch/mips have EXTRA_AFLAGS := $(CFLAGS) line.

| | | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data.
