MIPS: Align kernel load address to 64KB

2019-04-04T15:13:43+00:00

commit bec0de4cfad21bd284dbddee016ed1767a5d2823 upstream.

KEXEC needs the new kernel's load address to be aligned on a page
boundary (see sanity_check_segment_list()), but on MIPS the default
vmlinuz load address is only explicitly aligned to 16 bytes.

Since the largest PAGE_SIZE supported by MIPS kernels is 64KB, increase
the alignment calculated by calc_vmlinuz_load_addr to 64KB.

MIPS: Fix clean of vmlinuz.{32,ecoff,bin,srec}

2018-06-16T21:21:56+00:00

commit 5f2483eb2423152445b39f2db59d372f523e664e upstream.

Make doesn't expand shell style "vmlinuz.{32,ecoff,bin,srec}" to the 4
separate files, so none of these files get cleaned up by make clean.
List the files separately instead.

commit 26f7c4bd05cf34e63a4a794150ab66a40a5a84a9 upstream.

These are generated by very recent toolchains and result in an error
message when attenpting to convert a kernel from ELF to ECOFF.

MIPS: ZBOOT: add missing include

2014-10-05T20:41:02+00:00

commit 29593fd5a8149462ed6fad0d522234facdaee6c8 upstream.

Commit dc4d7b37 (MIPS: ZBOOT: gather string functions into string.c)
moved the string related functions into a separate file, which might
cause the following build error, depending on the configuration:

| CC      arch/mips/boot/compressed/decompress.o
| In file included from linux/arch/mips/boot/compressed/../../../../lib/decompress_unxz.c:234:0,
|                  from linux/arch/mips/boot/compressed/decompress.c:67:
| linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c: In function 'fill_temp':
| linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c:162:2: error: implicit declaration of function 'memcpy' [-Werror=implicit-function-declaration]
| cc1: some warnings being treated as errors
| linux/scripts/Makefile.build:308: recipe for target 'arch/mips/boot/compressed/decompress.o' failed
| make[6]: *** [arch/mips/boot/compressed/decompress.o] Error 1
| linux/arch/mips/Makefile:308: recipe for target 'vmlinuz' failed

It does not fail with the standard configuration, as when
CONFIG_DYNAMIC_DEBUG is not enabled  gets included in
include/linux/dynamic_debug.h. There might be other ways for it to
get indirectly included.

We can't add the include directly in xz_dec_stream.c as some
architectures might want to use a different version for the boot/
directory (see for example arch/x86/boot/string.h).

mips: delete non-required instances of include

2014-01-24T21:39:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

MIPS: ZBOOT: gather string functions into string.c

2014-01-24T21:39:55+00:00

In the worst case this adds less then 128 bytes of code
but on the other hand this makes code organization more clear.

MIPS: ZBOOT: Support LZ4 compression scheme

2013-10-29T20:24:34+00:00

Add support for the LZ4 compression scheme in the ZBOOT decompression
stub, in order to support it we need to:

- select the "lz4" compression tool to compress the vmlinux.bin
  payload
- memcpy() is also required for decompress_unlz4.c so we share the
  implementation between GZIP, XZ and now LZ4
