mips: sync asm/mipsregs.h with Linux 5.7

2020-07-18T12:23:25+00:00

Sync asm/mipsregs.h with Linux 5.7. Also replace the custom
symbols EBASE_CPUNUM and EBASE_WG with the according symbols
from Linux.

mips: traps: Set WG bit in EBase register on Octeon

2020-07-18T12:23:25+00:00

WG (bit 11) needs to be set on Octeon to enable writing bits 63:30 of
the exception base register.

MIPS: move create_tlb() in an proper header: mipsregs.h

2018-12-19T14:23:01+00:00

Export create_tlb() as an inline function in mipsregs.h. It allows to
remove the declaration of the function from the board files.

Then it will allow also to use this function very early in the boot when
the stack is not usable.

MIPS: remove local_irq_[save|restore] from CP0 macros

2018-12-19T14:23:01+00:00

With moving write_on_tlb() to arch/mips/include/asm/mipsregs.h
there are now compiler warnings when some generic code includes
asm/io.h. This happens for example when enabling OF live tree.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

MIPS: fix iand optimize setup of CP0 registers

2016-11-30T15:11:46+00:00

Clear cp0 status while preserving implementation specific bits.
Set bits BEV and ERL as the arch specification requires after
a reset or soft-reset exception.

Extend and fix initialization of watch registers. Check if additional
watch register sets are implemented and initialize them too.

Initialize cp0 count as early as possible to get the most
accurate boot timing.

MIPS: Hang if run on a secondary CPU

2016-09-21T15:04:53+00:00

Some systems are configured such that multiple CPUs begin running from
their reset vector following a system reset. If this occurs then U-Boot
will be run on multiple CPUs simultaneously, which causes all sorts of
issues as the multiple instances of U-Boot clobber each other.

Prevent this from happening by simply hanging with an infinite loop if
we run on a CPU whose ID, as determined by GlobalNumber or EBase.CPUNum
as appropriate, is non-zero.
