* remove __ARCH_WANT_COMPAT_SYS_PTRACEChristoph Hellwig2008-11-30
| | | | | | | | | | | | | All architectures now use the generic compat_sys_ptrace, as should every new architecture that needs 32bit compat (if we'll ever get another). Remove the now superflous __ARCH_WANT_COMPAT_SYS_PTRACE define, and also kill a comment about __ARCH_SYS_PTRACE that was added after __ARCH_SYS_PTRACE was already gone.

* MIPS: Make BUG() __noreturn.David Daney2008-11-24
| | | | | | | | | | | | | | | | | | | | Often we do things like put BUG() in the default clause of a case statement. Since it was not declared __noreturn, this could sometimes lead to bogus compiler warnings that variables were used uninitialized. There is a small problem in that we have to put a magic while(1); loop to fool GCC into really thinking it is noreturn. This makes the new BUG() function 3 instructions long instead of just 1, but I think it is worth it as it is now unnecessary to do extra work to silence the 'used uninitialized' warnings. I also re-wrote BUG_ON so that if it is given a constant condition, it just does BUG() instead of loading a constant value in to a register and testing it.

* MIPS: RB532: Provide functions for gpio configurationPhil Sutter2008-11-20
| | | | | | | | | | 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>

* MIPS: RB532: GPIO register offsets are relative to GPIOBASEFlorian Fainelli2008-11-20
| | | | | | | | | | | | | 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.

* MIPS: Sort out CPU type to name translation.Ralf Baechle2008-10-30
| | | | | | | | | | | | | 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.

* MIPS: Switch FPU emulator trap to BREAK instruction.Ralf Baechle2008-10-30
| | | | | | | | | | | | 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.

* MIPS: TXx9: Make firmware parameter passing more robustGeert Uytterhoeven2008-10-27
| | | | | | | | | | | | | | 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.
