Pass 1 parts had a number of significant erratas and were only available in small numbers and under NDA. Full support also required the use of a special toolchain that kept branches properly aligned. These workarounds were never upstreamed and the only toolchain known to have them is Montavista's GCC 3.0-based toolchain which completly obsoleted if not useless these days. So now that automated testing has tripped over the user of the -msb1-pass1-workarounds option, rather than fixing it remove support for pass 1 parts. Probably nobody will notice. I seem to own the last know pass 1 board and I haven't noticed another one in the wild in the past decade, at least. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

byte order. These modes require different kernels and a different

Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which

require workarounds. Without workarounds the system may hang

unexpectedly. For more information please refer to the gas
|

-mfix-loongson2f-nop and -mfix-loongson2f-jump options.

Loongson 2F03 and later have fixed these issues and no workarounds
|

are needed. The workarounds have no significant side effect on them
|

but may decrease the performance of the system so this option should

The kernel memory allocator divides physically contiguous memory

blocks into "zones", where each zone is a power of two number of

pages. This option selects the largest power of two that the kernel

keeps in the memory allocator. If you need to allocate very large

blocks of physically contiguous memory, then you may need to

increase this value.

This config option is actually maximum order plus one. For example,
|

a value of 11 means that the largest free memory block is 2^10 pages.

The page size is not necessarily 4KB. Keep this in mind

when choosing a value for this option.

When this is enabled, the kernel will support use of 64-bit floating

EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On

32-bit MIPS systems this support is at the cost of increasing the

size and complexity of the compiled FPU emulator. Thus if you are

running a MIPS32 system and know that none of your userland binaries

will require 64-bit floating point, you may wish to reduce the size
|

of your kernel & potentially improve FP emulation performance by

saying N here.

behaviour before the details have been finalised, this option should

be considered experimental and only enabled by those working upon

said details.

With this option, the boot code will look for a device tree binary

DTB) appended to raw vmlinux.bin (without decompressor).
|

(e.g. cat vmlinux.bin <filename>.dtb > vmlinux_w_dtb).
|

This is meant as a backward compatibility convenience for those
|

systems with a bootloader that can't be upgraded to accommodate

the documented boot protocol using a device tree.

Beware that there is very little in terms of protection against
|
|
this option being confused by leftover garbage in memory that might
|
|
look like a DTB header after a reboot if no actual DTB is appended
|
|
to vmlinux.bin. Do not leave this option active in a production kernel
|

if you don't intend to always append a DTB.

The Extended Industry Standard Architecture (EISA) bus was
|
|
developed as an open alternative to the IBM MicroChannel bus.
|
|
|
|
The EISA bus provided some of the features of the IBM MicroChannel
|
|
bus while maintaining backward compatibility with cards made for
|
|
the older ISA bus. The EISA bus saw limited use between 1988 and
|
|
1995 when it was made obsolete by the PCI bus.
|
|
|
|
Say Y here if you are building a kernel for an EISA-based machine.
|
|

Otherwise, say N.
