2008-11-20MIPS: csrc-r4k: Fix spelling mistake.Ralf Baechle
Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-11-20MIPS: RB532: Provide functions for gpio configurationPhil Sutter
As gpiolib doesn't support pin multiplexing, it provides no way to access the GPIOFUNC register. Also there is no support for setting interrupt status and level. These functions provide access to them and are needed by the CompactFlash driver. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-11-20MIPS: IP22: Make indy_sc_ops variable staticDmitri Vorobiev
The indy_sc_ops variable in arch/mips/mm/sc-ip22.c is needlessly defined global, and this patch makes it static. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@movial.fi> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> ---
2008-11-20MIPS: RB532: GPIO register offsets are relative to GPIOBASEFlorian Fainelli
This patch fixes the wrong use of GPIO register offsets in devices.c. To avoid further problems, use gpio_get_value to return the NAND status instead of our own expanded code. Also define the zero offset of the alternate function register to allow consistent access.

2008-11-20MIPS: Malta: Fix include paths in malta-amon.cDavid Daney
On linux-queue, malta doesn't build after the include file relocation. This should fix it. There some occurrences of 'asm-mips' in the comments of quite a few files, but this is the only place I found it in any code.

2008-10-30CHAR: Delete old and now unused M48T35 RTC driver for SGI IP27.Ralf Baechle
It was only used by this one SGI platform which recently was converted to RTC_LIB and with RTC_LIB enabled the legacy drivers are no more selectable. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-30CHAR: Delete old and now unused DS1286 driver.Ralf Baechle
It was only used by two SGI platforms which recently were converted to RTC_LIB and with RTC_LIB enabled the legacy drivers are no more selectable. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Yoichi Yuasa <yoichi_yuasa@tripeaks.co.jp>
2008-10-30MIPS: Sort out CPU type to name translation.Ralf Baechle
As noticed by David Daney <ddaney@caviumnetworks.com>, the old long switch statement did not comply with the Linux C coding style. It was also yet another place of code to be changed when adding a new processor type leading to annoying bugs for example in /proc/cpuinfo. Fixed by moving the setting of the CPU type string into the core of the probing code and a few BUG_ON() test to ensure the CPU probing code indeed did its job and removing multiple now redundant tests.

2008-10-30MIPS: Switch FPU emulator trap to BREAK instruction.Ralf Baechle
Arguably using the address error handler has always been ugly. But with processors that handle unaligned loads and stores in hardware the current mechanism ceases to work so switch it to a BREAK instruction and allocate break code 514 to the FPU emulator. Yoichi Yuasa provided a build fix for CONFIG_BUG=n. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Yoichi Yuasa <yoichi_yuasa@tripeaks.co.jp>
2008-10-30MIPS: SMP: Do not initialize __cpu_number_map/__cpu_logical_map for CPU 0.Ralf Baechle
A system isn't necessarily booted on physical processor 0 as this code assumes. Also the array happens to be allocated in .bss so it's zero initialized anyway. Systems which need to override this can do so in their mp_ops->smp_setup() method. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-30MIPS: Consider value of c0_ebase when computing value of exception base.David Daney
It just so happens to be zero on all currently supported systems so this hasn't bitten yet ...

2008-10-27MIPS: TXx9: Make firmware parameter passing more robustGeert Uytterhoeven
When booting Linux on a txx9 board with VxWorks boot loader, it crashes in prom_getenv(), as VxWorks doesn't pass firmware parameters in a0-a3 (in my case, the actual leftover values in these registers were 0x80002000, 0x80001fe0, 0x2000, and 0x20). Make the parsing of argc, argv, and envp a bit more robust by checking if argc is a number below CKSEG0, and argv/envp point to CKSEG0.
