MIPS: ath79: Add zboot debug serial support

2016-05-13T12:01:37+00:00

Reuse the early printk code to support the serial in zboot. We copy
early_printk.c instead of referencing it because we need to build a
different object file for the normal kernel and zboot.

MIPS: zboot: Remove copied source files on clean

2016-04-03T08:37:21+00:00

The copied source files must be added to the extra-y list to have them
removed on clean.

MIPS: zboot: Fix the build with XZ compression on older GCC versions

2016-04-03T08:37:13+00:00

Some older GCC version (at least 4.6) emits calls to __bswapsi2() when
building the XZ decompressor. The link of the compressed image then
fails with the following error:

arch/mips/boot/compressed/decompress.o: In function '__fswab32':
include/uapi/linux/swab.h:60: undefined reference to '__bswapsi2'

Add bswapsi.o to the link to fix the build with these versions.

MIPS: zboot: Add support for serial debug using the PROM

2016-01-24T03:05:51+00:00

As most platforms implement the PROM serial interface prom_putchar()
add a simple bridge to allow re-using this code for zboot.

MIPS: zboot: Avoid useless rebuilds

2016-01-24T03:05:03+00:00

Add dummy.o to the targets list, and fill targets automatically from
$(vmlinuzobjs) to avoid having to maintain two lists.

When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.

MIPS: Fix alignment of quiet build output for vmlinuz link

2015-09-03T10:08:15+00:00

The "LD vmlinuz" line in the quiet build output is misaligned with the
rest of the output. Fix this.

MIPS: Reduce kernel image size for !CONFIG_DEBUG_ZBOOT

2015-04-02T11:54:25+00:00

!CONFIG_DEBUG_ZBOOT doesn't need puts() and puthex(), remove them and
the corrospindig strings for !CONFIG_DEBUG_ZBOOT, as a result, it saves
about 1280 bytes.

MIPS: Allow platforms to specify the decompressor load address

2015-03-31T10:04:12+00:00

Platforms which use raw zboot images may need to link the image at
a fixed address if there is no other way to communicate the load
address to the bootloader.  Allow the per-platform Kbuild files
to specify an optional zboot image load address (zload-y) and fall
back to calc_vmlinuz_load_addr if unset.

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
