* [MIPS] Malta: remaining bits of the board support code cleanupDmitri Vorobiev2008-01-291-38/+42
| | | | | | | | | | | | This patch factors out the code, which handles the Bonito system controller. The case of not supporting the DMA coherency is handled separately to make the logic obvious. Besides, a couple of empty lines added to beautify the code even further. No functional changes introduced.

* [MIPS] Malta: Fix reading the PCI clock frequency on big-endianDmitri Vorobiev2008-01-221-1/+1
| | | | | | | | | | | | | | | | | | The JMPRS register on Malta boards keeps a 32-bit CPU-endian value. The readw() function assumes that the value it reads is a little-endian 16-bit number. Therefore, using readw() to obtain the value of the JMPRS register is a mistake. This error leads to incorrect reading of the PCI clock frequency on big-endian during board start-up. Change readw() to __raw_readl(). This was tested by injecting a call to printk() and verifying that the value of the jmpr variable was consistent with current setting of the JP4 "PCI CLK" jumper.

* [MIPS] Malta: Fix software reset on big endianDmitri Vorobiev2008-01-111-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that the commit f197465384bf7ef1af184c2ed1a4e268911a91e3 (MIPS Tech: Get rid of volatile in core code) broke the software reset functionality for MIPS Malta boards in big-endian mode. According to the MIPS Malta board user's manual, writing the magic 32-bit GORESET value into the SOFTRES register initiates board soft reset. My experimentation has shown that the endianness of the GORESET integer should thereby be the same as the endianness, which has been set for the CPU itself. The writew() function used to write the magic value in the code introduced by the commit mentioned above, however, swaps bytes for big-endian kernels and transfers 16 bits instead of 32. The patch below replaces the writew() function by the __raw_writel() routine, which leaves the byte order intact and transfers the whole MIPS machine word. Trivial code cleanup (replacing spaces by a tab and cutting oversized lines to make checkpatch.pl happy) is also included. The patch was tested using a Malta evaluation board running in both BE and LE modes. For both modes, software reset was fully functional after the change. P.S. I suspect that the same commit broke the "standby" functionality for MIPS Atlas boards. However, I did not touch the Atlas code as I don't have such board at my disposal and also because the linux-mips.org Web site claims that Atlas support is scheduled for removal.

* [MIPS] Dyntick support for SMTC:Ralf Baechle2007-10-121-1/+0Star
| | | | | | | | | The kernel currently only supports broadcasting of the timer interrupt from a single timer, not multicasting into two multicast groups of processors. So the implemented mechanism for SMTC works by broadcasting the cp0 compare interrupt on VPE 0 and ignoring it on any additional VPEs. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
