MIPS: rename M6201 core to M6250

2016-11-09T21:42:12+00:00

m6201 is the -march option for GCC, but the real core name is M6250. Signed-off-by: Vicente Olivert Riera Reviewed-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

arch/Config.in.mips: add support for XBurst cores

2016-11-09T20:36:34+00:00

The Ingenic XBurst is a MIPS32R2 microprocessor. It has a bug in the FPU that can generate incorrect results in certain cases. The problem shows up when you have several fused madd instructions in sequence with dependant operands. Using the -mno-fused-madd option prevents gcc from emitting these instructions. This patch adds changes to the toolchain wrapper to use that option. Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

MIPS: add support for M6201 cores

2016-10-19T21:31:29+00:00

-march=m6201 is not yet supported in GCC upstream, so disabling all versions when selecting this core. Note that M6201 implies a MIPS R6 CPU, and some GCC versions are already disabled for R6, so we don't need to disable those ones for M6201 as well. The external Codescape IMG GNU Linux Toolchain has support for this core. Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

MIPS: add support for I6400 cores

2016-10-15T11:22:17+00:00

-march=i6400 support starts from GCC-6, so disable previous versions when selecting this core. Note that I6400 implies a MIPS R6 CPU, and some GCC versions are already disabled for R6, so we don't need to disable those ones for I6400 as well.

Note that M5101 implies a MIPS R5 CPU, and some GCC versions are already disabled for R5, so we don't need to disable those ones for M5101 as well. Also disable external toolchains that don't support this core. Signed-off-by: Vicente Olivert Riera Signed-off-by: Peter Korsgaard
