MIPS: ath79: Add a machine entry for booting OF machines

2015-11-20T14:44:57+00:00

As I'm using a board with a broken old bootloader I hardcoded the
mips_machtype and did't notice that the machine entry was still
missing.

MIPS: ath79: Fix the size of the MISC INTC registers in ar9132.dtsi

2015-11-20T11:14:27+00:00

There is 2 registers that is 8 bytes long, not 4.

MIPS: ath79: Fix the DDR control initialization on ar71xx and ar934x

2015-11-20T11:10:09+00:00

The DDR control initialization needs to know the SoC type, however
ath79_detect_sys_type() was called after ath79_ddr_ctrl_init().
Reverse the order to fix the DDR control initialization on ar71xx and
ar934x.

MIPS: Fix flood of warnings about comparsion being always true.

2015-11-16T11:07:10+00:00

./arch/mips/include/asm/page.h:204:13: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]

The default value of ARCH_PFN_OFFSET is 0 thus triggering this warning
for all platforms using the default value.

MIPS: idle: add case for CPU_5KE

2015-11-12T10:35:48+00:00

While the 5KE processors have never been taped out, they exists though
a CP0.PRId and experimental RTLs or QEMU implementations. Add a case
entry in the idle code, as they can use the standard idle loop like the
5K processors.

MIPS: vmlinux: create a section for appended DTB

2015-11-12T10:35:48+00:00

For bootloaders that support booting only ELF kernels and load only ELF
segments to memory there is no easy way to supply DTB without kernel
recompilation. For that purpose, create a section called .appended_dtb
that can be later updated with board-specific DTB using binutils e.g. at
kernel installation time.

MIPS: Clean up compat_siginfo_t

2015-11-12T10:35:47+00:00

While mips can't use the generic compat_siginfo_t directly because
its si_code and si_errno are inverted, we can still make it as
close to the generic version as possible. This makes it easier
to update when new members are added to siginfo_t.

The main changes are adding a missing _sigsys union member and
eliminating the unused _irix_sigchld one.
