This patch fixes a couple of missing dependencies in arch/powerpc/boot/Makefile. First, it ensures that the zlib.h header is linked in before attempting to build gunzip_util.o, as it is, building gunzip_util.o usually works, but not always depending on make order. Second, it makes the final images which are built using a dts dependent on that dts, so the image will be correctly rebuilt if the dts changes. This in turn requires fixing the definition of the dts variable. CONFIG_DEVICE_TREE from Kconfig will have quotes around it, which don't matter when passing the variable to a shell, but which need to be removed when incorporating it into a filename for make's use.

This patch makes a few small cleanups to the cuboot code. - It removes the double layered selection of images, via cuboot-plat-y, instead having the cuboot platforms directly select a suitable image-y (this changes the name of the final cuboot image from plain cuImage to cuImage.<platform>). - Factors out some code in the wrapper that's potentially useful to platforms other than uboot.

This patch adds a library of useful device tree manipulation functions to the zImage library, for use by platform code. These functions are based on the hooks already in dt_ops, so they're not dependent on a particular device tree implementation. This patch also slightly streamlines the code in main.c using these new functions. This is a consolidation of my work in this area with Scott Wood's patches to a very similar end.

Before the plethora of platforms gets any worse, establish a common rule to invoke the wrapper for any platform. Add arguments to the rule for initrd, dts, dtb, etc. Show example usage with initrd. Create default rules for zImage, and zImage.initrd. initrd targets depend on the ramdisk file. Don't consider targets for zImage.initrd that are targets for zImage. This means uImage is no longer considered a target for zImage.initrd. Signed-off-by: NMilton Miller <miltonm@bga.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

This patch re-organises the way the zImage wrapper code is entered, to allow more flexibility on platforms with unusual entry conditions. After this patch, a platform .o file has two options: 1) It can define a _zimage_start, in which case the platform code gets control from the very beginning of execution. In this case the platform code is responsible for relocating the zImage if necessary, clearing the BSS, performing any platform specific initialization, and finally calling start() to load and enter the kernel. 2) It can define platform_init(). In this case the generic crt0.S handles initial entry, and calls platform_init() before calling start(). The signature of platform_init() is changed, however, to take up to 5 parameters (in r3..r7) as they come from the platform's initial loader, instead of a fixed set of parameters based on OF's usage. When using the generic crt0.S, the platform .o can optionally supply a custom stack to use, using the BSS_STACK() macro. If this is not supplied, the crt0.S will assume that the loader has supplied a usable stack. In either case, the platform code communicates information to the generic code (specifically, a PROM pointer for OF systems, and/or an initrd image address supplied by the bootloader) via a global structure "loader_info". In addition the wrapper script is rearranged to ensure that the platform .o is always linked first. This means that platforms where the zImage entry point is at a fixed address or offset, rather than being encoded in the binary header can be supported using option (1).

At present, arch/powerpc/boot/main.c includes a gunzip() function which is a convenient wrapper around zlib. However, it doesn't conveniently allow decompressing part of an image to one location, then the remainder to a different address. This patch adds a new set of more flexible convenience wrappers around zlib, moving them to their own file, gunzip_util.c, in the process. These wrappers allow decompressing sections of the compressed image to different locations. In addition, they transparently handle uncompressed data, avoiding special case code to handle uncompressed vmlinux images. The patch also converts main.c to use the new wrappers, using the new flexibility to avoid decompressing the vmlinux's ELF header twice as we did previously. That in turn means we avoid extending our allocations for the vmlinux to allow space for the extra copy of the ELF header.

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. Signed-off-by: NPaul Mackerras <paulus@samba.org>

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.
