* [POWERPC] Start arch/powerpc/boot code reorganizationMark A. Greer2006-09-20
| | | | | | | | | | | | | | | This abstracts the operations used in the bootwrapper, and defines the operations needed for the bootwrapper to run on an OF platform. The operations have been divided up into platform ops (platform_ops), firmware ops (fw_ops), device tree ops (dt_ops), and console ops (console_ops). The proper operations will be hooked up at runtime to provide the functionality that you need. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

* | [POWERPC] Add -fno-stack-protector to BOOTCFLAGS in arch/powerpc/boot/Makefile.Niels Kristian Bech Jensen2006-07-07
|/ | | | | | | | | | | | | | | | I got some undefined references to __stack_chk_fail in arch/powerpc/boot/stdio.o and arch/powerpc/boot/prom.o when I was trying to build a kernel on Ubuntu Edgy Eft - which includes Stack Smashing Protection. This patch adds -fno-stack-protector to BOOTCFLAGS in arch/powerpc/boot/Makefile (why does BOOTCFLAGS depend on HOSTCFLAGS and not CFLAGS?).

* | [PATCH] zlib_inflate: Upgrade library code to a recent versionRichard Purdie2006-06-22
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/32: Generate miboot images with ARCH=powerpcPaul Mackerras2006-01-14

* powerpc: Avoid unaligned loads and stores in boot memcpy codePaul Mackerras2006-01-13
| | | | | | | | | | | | | | 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. Signed-off-by: Paul Mackerras <paulus@samba.org>
