* [ARM] 3809/3: get rid of 4 megabyte kernel image size limitLennert Buytenhek2006-09-301-1/+2
| | | | | | | | | | | | | | | | | | | | | We currently have a hardcoded 4 megabyte uncompressed kernel image size limit, which is easily exceeded by, for example, enabling some of the various kernel debugging options. When setting up the initial page tables (which is where this 4M limit is hardcoded), it's actually relatively easy to find out the true size of the uncompressed kernel image and create enough page table entries for things to fit, so this patch makes it so. In the decompressor, we also need to know the size of the uncompressed kernel image, to figure out whether there is any chance that uncompressing the kernel might overwrite the compressed kernel image stored elsewhere in memory. We don't have that info at this boot stage, though, so we approximate the size of the uncompressed kernel by taking the compressed kernel image size and allowing for a maximum 4x expansion.

* | kbuild: change kbuild to not rely on incorrect GNU make behaviorPaul Smith2006-03-062-2/+8
|/ | | | | | | | | | | | | | | | | | | | The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

* [ARM] Allow r2 to be passed through the decompressor to the kernelRussell King2006-01-121-21/+25
| | | | | | | | | | | | | | | | This is part of a patch from Marc Singer to allow r2 to be passed to the kernel. Marc's original comments follow: This revised R2 (atags pointer) patch incorporates comments from Nico Pitre and Ben Dooks. It modifies the head.S files such that the R2 value set by the bootloader is conveyed to the kernel startup code. The kernel head.S heuristically validates the pointer. It will set R2 to zero if it believes the pointer is invalid. Presently, it requires that the ATAGS list reside in the first 16KiB of physical RAM. Relaxing this contraint may be both desirable as well as tricky. Signed-off-by: Marc Singer <elf@buici.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [PATCH] use ${CROSS_COMPILE}installkernel in arch/*/boot/install.shIan Campbell2005-06-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | The attached patch causes the various arch specific install.sh scripts to look for ${CROSS_COMPILE}installkernel rather than just installkernel (in both /sbin/ and ~/bin/ where the script already did this). This allows you to have e.g. arm-linux-installkernel as a handy way to install on your cross target. It also prevents the script picking up on the host /sbin/installkernel which causes the script to fall through and do the install itself (which is what I actually use myself, with $INSTALL_PATH set). I don't believe it causes back-compatibility problems since calling the host installkernel was never likely to work or be what you wanted when cross compiling anyway. If $CROSS_COMPILE isn't set then nothing changes. I only use ARM and i386 myself but I figured it couldn't hurt to do the whole lot. I've cc'd those who I hope are the arch maintainers for files that I've touched.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
