MIPS: SGI-IP27: fix readb/writeb addressing

2020-01-09T23:30:56+00:00

Our chosen byte swapping, which is what firmware already uses, is to do readl/writel by normal lw/sw intructions (data invariance). This also means we need to mangle addresses for u8 and u16 accesses. The mangling for 16bit has been done aready, but 8bit one was missing. Correcting this causes different addresses for accesses to the SuperIO and local bus of the IOC3 chip. This is fixed by changing byte order in ioc3 and m48rtc_rtc structs.

MIPS: SGI-IP27: Only reserve interrupts used in Linux

2020-01-09T23:30:04+00:00

Reduce number of reserved interrupts by removing bits copied from IRIX and not used by Linux. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Move all shared IP27 declarations to ip27-common.h

2020-01-09T23:30:03+00:00

Move all IP27 declarations into one file. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Use specific get_region_shift

2020-01-09T23:30:01+00:00

IP35 has a different way to find out regions, so we move the IP27 implementation to IP27 specific file. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Split kldir.h into generic SN and IP27 parts

2020-01-09T23:29:56+00:00

SGI-IP35 uses slightly different memory layout, so we move IP27 defines to IP27 specific files and keep the common stuff in kldir.h Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Move get_nasid() to a IP27 specific file

2020-01-09T23:29:54+00:00

get_nasid() will be different for SGI-IP35, therefore move IP27 implementation to IP27 specific file. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: move IP27 specific macro to IP27 specific header file

2020-01-09T23:29:53+00:00

Extracting node id from HUB register is specific to IP27 alias SN0. Move the macro definition to a SN0 header file. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: get rid of asm/sn/sn0/ip27.h

2020-01-09T23:29:51+00:00

The only piece needed in ip27.h is SEND_NMI. Move the define to the only place where it's used and remove ip27.h Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org
