[POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot 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: Paul Mackerras <paulus@samba.org>

powerpc: Use scripts/mkuboot.sh instead of 'mkimage' mkuboot.sh provides a basic wrapper for the 'mkimage' utility. Using mkuboot.sh provides clearer error reporting and allows a toolchain to use its own 'mkimage' executable specified by ${CROSS_COMPILE}mkimage. Additionally, this brings PowerPC in line with other architectures which already call mkimage via mkuboot.sh.

[POWERPC] bootwrapper: Build multiple cuImages Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image with a fdt blob which means for any given configuration only one dts file can be selected and so support for only one board can be built This moves the selection of the default .dts file out of the kernel config and into the bootwrapper makefile. The makefile chooses which images to build based on the kernel config and the dts source file name is taken directly from the image name. For example "cuImage.ebony" will use "ebony.dts" as the device tree source file. In addition, this patch allows a specific image to be requested from the command line by adding "cuImage.%" and "treeImage.%" targets to the list of valid built targets in arch/powerpc/Makefile. This allows the default dts selection to be overridden. Another advantage to this change is it allows a single defconfig to be supplied for all boards using the same chip family and only differing in the device tree. Important note: This patch adds two new zImage targets; zImage.dtb.% and zImage.dtb.initrd.% for zImages with embedded dtb files. Currently there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc, adder875-redboot and ep8248e. This patch *changes the zImage filenames* for those platforms. ie. 'zImage.ps3' is now 'zImage.dtb.ps3'. This new zImage.dtb targets were added so that the .dts file could be part of the dependancies list for building them.

[POWERPC] bootwrapper: Build multiple cuImages Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image with a fdt blob which means for any given configuration only one dts file can be selected and so support for only one board can be built This moves the selection of the default .dts file out of the kernel config and into the bootwrapper makefile. The makefile chooses which images to build based on the kernel config and the dts source file name is taken directly from the image name. For example "cuImage.ebony" will use "ebony.dts" as the device tree source file. In addition, this patch allows a specific image to be requested from the command line by adding "cuImage.%" and "treeImage.%" targets to the list of valid built targets in arch/powerpc/Makefile. This allows the default dts selection to be overridden. Another advantage to this change is it allows a single defconfig to be supplied for all boards using the same chip family and only differing in the device tree. Important note: This patch adds two new zImage targets; zImage.dtb.% and zImage.dtb.initrd.% for zImages with embedded dtb files. Currently there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc, adder875-redboot and ep8248e. This patch *changes the zImage filenames* for those platforms. ie. 'zImage.ps3' is now 'zImage.dtb.ps3'. This new zImage.dtb targets were added so that the .dts file could be part of the dependancies list for building them.

[POWERPC] PS3: Bootwrapper support. Add support to build the PS3 flash rom image and remove some unneeded lmb calls. The PS3's lv1 loader supports loading gzipped binary images from flash rom to addr zero. The loader enters the image at addr 0x100. In this implementation a bootwrapper overlay is use to arrange for the kernel to be loaded to addr zero and to have a suitable bootwrapper entry at 0x100. To construct the rom image, 0x100 bytes from offset 0x100 in the kernel is copied to the bootwrapper symbol __system_reset_kernel. The 0x100 bytes at the bootwrapper symbol __system_reset_overlay is then copied to offset 0x100. At runtime the bootwrapper program copies the 0x100 bytes at __system_reset_kernel to addr 0x100. zImage.ps3 is a wrapped image that contains a flat device tree, an lv1 compatible entry point, and an optional initrd. otheros.bld is the gzip compresed rom image built from zImage.ps3. otheros.bld is suitable for programming into the PS3 boot flash memory.

powerpc: Change the default link address for pSeries zImage kernels Currently we set the start of the .text section to be 4Mb for pSeries. In situations where the zImage is > 8Mb we'll fail to boot (due to overlapping with OF). Move .text in a zImage from 4MB to 64MB (well past OF). We still will not be able to load large zImage unless we also move OF, to that end, add a note to the zImage ELF to move OF to 32Mb. If this is the very first kernel booted then we'll need to move OF manually by setting real-base. Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot 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: Paul Mackerras <paulus@samba.org>

[POWERPC] bootwrapper: Make compression of the kernel image optional. The --no-gzip option can be passed to the wrapper so that the kernel image is included uncompressed into the zImage. This is intended for bootloaders where the zImage itself can be compressed, or where boot time is considered more important than kernel image size.

powerpc: Change the default link address for pSeries zImage kernels Currently we set the start of the .text section to be 4Mb for pSeries. In situations where the zImage is > 8Mb we'll fail to boot (due to overlapping with OF). Move .text in a zImage from 4MB to 64MB (well past OF). We still will not be able to load large zImage unless we also move OF, to that end, add a note to the zImage ELF to move OF to 32Mb. If this is the very first kernel booted then we'll need to move OF manually by setting real-base. Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] zImage: Cleanup and improve zImage entry point 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).

It turns out that this causes unnecessary extra reboots on old 32-bit CHRP machines. This therefore adds a -r flag to addnote to allow us to specify what real-base value it should put in the CHRP note, and adjusts the wrapper script to pass -r c00000 to addnote when making a zImage for a CHRP machine. Also, CHRP machines ignore the RPA note, so we don't need to arrange for it to be the same as the kernel's.

[POWERPC] PS3: Bootwrapper improvements Improve the debugging support of the PS3 bootwraper code: o Increase the size of the PS3 bootwrapper overlay from 256 to 512 bytes to allow for more debugging code in the overlay. o Use the dot symbol to set the size of __system_reset_overlay. The assembler will then emit an error if the overlay code is too big. o Remove some unused instructions. o Update the text describing the PS3 bootwrapper overlay. o Add a check for null pointer writes. o Change hcall return value from s64.

[POWERPC] PS3: Bootwrapper support. Add support to build the PS3 flash rom image and remove some unneeded lmb calls. The PS3's lv1 loader supports loading gzipped binary images from flash rom to addr zero. The loader enters the image at addr 0x100. In this implementation a bootwrapper overlay is use to arrange for the kernel to be loaded to addr zero and to have a suitable bootwrapper entry at 0x100. To construct the rom image, 0x100 bytes from offset 0x100 in the kernel is copied to the bootwrapper symbol __system_reset_kernel. The 0x100 bytes at the bootwrapper symbol __system_reset_overlay is then copied to offset 0x100. At runtime the bootwrapper program copies the 0x100 bytes at __system_reset_kernel to addr 0x100. zImage.ps3 is a wrapped image that contains a flat device tree, an lv1 compatible entry point, and an optional initrd. otheros.bld is the gzip compresed rom image built from zImage.ps3. otheros.bld is suitable for programming into the PS3 boot flash memory.

[POWERPC] bootwrapper: Revert ps3 binary flag usage, and remove .bin suffix The ps3 target produces two images, and the binary one is not the "primary" image that corresponds to the -o flag; thus, it no longer uses the generic binary flag. On platforms which do use the binary flag, it no longer produces a .bin suffix, so that the output file matches what was passed to the -o flag. This should fix the zImage ln problems for the ps3 target.

[POWERPC] Create otheros.bld next to specified output file, not in $object directory The bootwrapper script currently generates an 'otheros.bld' file in addition to the file specified by the -o option, when asked to build a wrapper for PS3. It should do that in the same directory as the output, not the directory where the wrapper objects are kept (which might potentially not be writable when the script runs). Arguably, the 'otheros.bld' ought to be created with the filename specified as the -o argument. But that's a more intrusive change.

[POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot 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: Paul Mackerras <paulus@samba.org>
