      [POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot · 2bf11819
      由 Paul Mackerras 提交于 
      This puts the knowledge of how to create various sorts of zImage
wrappers into a script called "wrapper" that could be used outside of
the kernel tree.  This changes arch/powerpc/boot so it first builds
the files that the wrapper script needs, then runs it to create
whatever flavours of zImage are required.

This version does uImages as well.  The zImage names are changed
slightly; zImage.pseries is the one with the PT_NOTE program header
entry added, and zImage.pmac is the one without.  If the
zImage.pseries gets made, it will also get hardlinked to zImage;
otherwise, if zImage.pmac is made, it gets hardlinked to zImage.

      POWERPC: Bring the fs_no calculation to the relevant SoC enumeration · 611a15af
      由 Vitaly Bordug 提交于 
      The fs_no mean used to be fs_enet driver driven, hence it was an
enumeration across all the possible fs_enet "users" in the SoC. Now, with
QE on the pipeline, and to make DTS descriptions more clear, fs_no features
relevant SoC part number, with additional field to describe the SoC type.

Another reason for that is now not only fs_enet is going to utilize those
stuff. There might be UART, HLDC, and even USB, so to prevent confusion and
be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were
updated in that concern, as well as the relevant DTS.

      POWERPC: Add support for the mpc8560 eval board · 902f392d
      由 Vitaly Bordug 提交于 
      This makes the 8560 evaluation board fully supported under arch/powerpc,
as the first board with CPM2 SoC peripherals. The brand new devicetree
nodes are introduced (intending to be a subset of the QuiccEngine-equipped
models, with dts sources placed into the kernel according to the new convention.

Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART
update), the both TSEC eth ,FCC Eths, and both SCC UARTs are
working. The relevant drivers are still capable to drive users in ppc,
which was verified with 8272ADS (SCC uart+FCC eth).

This is also verified on mpc8540 and actually make it work (PCI stuff
working as well)

      [PATCH] zlib_inflate: Upgrade library code to a recent version · 4f3865fb
      由 Richard Purdie 提交于 
      Upgrade the zlib_inflate implementation in the kernel from a patched
version 1.1.3/4 to a patched 1.2.3.

The code in the kernel is about seven years old and I noticed that the
external zlib library's inflate performance was significantly faster (~50%)
than the code in the kernel on ARM (and faster again on x86_32).

For comparison the newer deflate code is 20% slower on ARM and 50% slower
on x86_32 but gives an approx 1% compression ratio improvement.  I don't
consider this to be an improvement for kernel use so have no plans to
change the zlib_deflate code.

Various changes have been made to the zlib code in the kernel, the most
significant being the extra functions/flush option used by ppp_deflate.
This update reimplements the features PPP needs to ensure it continues to
work.

This code has been tested on ARM under both JFFS2 (with zlib compression
enabled) and ppp_deflate and on x86_32.  JFFS2 sees an approx.  10% real
world file read speed improvement.

This patch also removes ZLIB_VERSION as it no longer has a correct value.
We don't need version checks anyway as the kernel's module handling will
take care of that for us.  This removal is also more in keeping with the
zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've
added something to the zlib.h header to note its a modified version.

      powerpc: Avoid unaligned loads and stores in boot memcpy code · b4e7de0f
      由 Paul Mackerras 提交于 
      The 601 processor will generate an alignment exception for accesses
which cross a page boundary.  In the boot wrapper code, OF is still
handling all exceptions, and it doesn't have an alignment exception
handler that emulates the instruction and continues.

This changes the memcpy and memmove routines in the boot wrapper to
avoid doing unaligned accesses.  If the source and destination are
misaligned with respect to each other, we just copy one byte at a
time.

      powerpc: Make COFF zImages for old 32-bit powermacs · 66a45dd3
      由 Paul Mackerras 提交于 
      This adds code to build zImage.coff and/or zImage.initrd.coff when
CONFIG_PPC32 and CONFIG_PPC_PMAC are defined.  It also restructures
the OF client code and adds some workarounds for OF quirks on the
older machines.
