The CPU_MIPS64 and CPU_MIPS32 variables are supposed to be able to distinguish broadly between 64-bit and 32-bit MIPS CPUs. However, they weren't selected by the specialty CPUs, Octeon and Loongson, which meant it was possible to hit a weird state of: MIPS=y, CONFIG_64BIT=y, CPU_MIPS64=n This commit rectifies the issue by having CPU_MIPS64 be selected when the missing Octeon or Loongson models are selected. In particular, this affects our octeonplus target.

Subject: [PATCH] MIPS: select CPU_MIPS64 for remaining MIPS64 CPUs
|
|
|
|
The CPU_MIPS64 and CPU_MIPS32 variables are supposed to be able to
|
|
distinguish broadly between 64-bit and 32-bit MIPS CPUs. However, they
|
|
weren't selected by the specialty CPUs, Octeon and Loongson, which meant
|
|
it was possible to hit a weird state of:
|
|
|
|
MIPS=y, CONFIG_64BIT=y, CPU_MIPS64=n
|
|
|
|
This commit rectifies the issue by having CPU_MIPS64 be selected when
|
|
the missing Octeon or Loongson models are selected.
