From Revision 36 to 17

Rev	Summary	Authors	Date
36	semi_loader: Handle dtbs with 64 bit addresses semi_loader: Handle dtbs with 64 bit addresses ARM board device tree blobs have moved to specifying addresses and sizes as 64 bit values (2 cells) rather than 32 bit (1 cell); update bootwrapper so it can handle these rather than stopping with an error. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Dave Martin <dave.martin@linaro.org>	Peter Maydell	11 years ago
35	semi_loader.c: make --dtb actually work rather than be ignor... semi_loader.c: make --dtb actually work rather than be ignored Fix a bug that meant that the --dtb option was silently ignored. (The equivalent to this fix has already been applied in the big.LITTLE bootwrapper which we borrow this file from, so this brings us back into sync.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
34	bootwrapper: Add README bootwrapper: Add README Add a short README file describing what the bootwrapper is and how to run it. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
33	bootwrapper: Switch to C semihosting code bootwrapper: Switch to C semihosting code Switch over to the C semihosting code, removing the old assembly implementation. This allows us to simplify the build process somewhat: boot.S is now compiled only once, rather than once for semihosting and once without. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
32	bootwrapper: Import C semihosting code bootwrapper: Import C semihosting code Import the reimplementation in C of the semihosting support written by Dave Martin for the ARM big.LITTLE bootwrapper. The main benefit of this switchover (apart from only having one implementation rather than two) is the fdt support it includes. This commit only imports the sources, it doesn't compile them. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
31	bootwrapper: Import libfdt flattened device tree library bootwrapper: Import libfdt flattened device tree library Import the sources of the libfdt flattened device tree library, as a prerequisite for adding fdt support to the bootwrapper. This commit just pulls in the upstream sources; it does not cause them to be built. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
30	Makefile: Use .PHONY target, not dummy commands; tidy clean ... Makefile: Use .PHONY target, not dummy commands; tidy clean list There's no need to use a dummy 'true' command to suppress the default 'try kernel makefile' target for targets with no actual rules -- you can just list as in .PHONY instead. Tidy the list of files to remove on clean to remove a duplicate and use $(KERNEL) instead of uImage. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
29	boot-wrapper: tidy the Makefile to help with packaging. boot-wrapper: tidy the Makefile to help with packaging. Add and modify Makefile rules so that it can be used in a Debian package. Add an explicit 'distclean' target. Add a 'semi' target that only builds the semihosting binary. Add stub commands to 'all' and 'semi' so the call doesn't fall through to the default kernel rule. Update 'clean' to also clean the semihosting files. Signed-off-by: Michael Hope <michael.hope@linaro.org> Signed-off-by: Rusty Russell <rusty.russell@linaro.org>	Michael Hope	12 years ago
28	model.lds.S: Move initrd address up to allow for large kerne... model.lds.S: Move initrd address up to allow for large kernels Move the start address of the initrd up to kernel start + 0xd00000, so that we can handle large kernels (eg Android) without them overlapping with the initrd. 0xd00000 is the offset QEMU uses in its internal ARM bootloader so should be sufficient. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
27	Boot kernel in hyp mode. Boot kernel in hyp mode. Leave the old monitor stub there for the moment, so we can boot current Christoffer kernels. Includes fixes by Dave Martin to make it actually work :) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Rusty Russell	12 years ago
26	Fix linux-system-semi.axf build failure from clean Fix linux-system-semi.axf build failure from clean We were failing to build linux-system-semi.axf in a clean tree because even if SEMIHOSTING was defined we still had a spurious INPUT(boot.o), which is harmless if boot.o exists but fails if it does not. In fact the INPUT() commands for the .o files are unnecessary because ld will pull in the correct .o files because the SECTIONS command has a non-wildcard reference to them. So just drop the unneeded INPUT() commands rather than adding more ifdefs. (The INPUT() commands for the binary blobs are still required.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
25	boot-wrapper: Support reading kernel/initrd via semihosting boot-wrapper: Support reading kernel/initrd via semihosting Implement support in the boot-wrapper for reading our kernel, initrd and command line arguments using the semihosting ABI provided by a Fast Model. We build a second AXF file linux-system-semi.axf which does not depend on or bake in a kernel binary. Instead when you start the model with it you pass the model a parameter like: -C cluster.cpu0.semihosting-cmd_line="--kernel /path/to/uImage --initrd /path/to/initrd -- console=ttyAMA0 mem=512M ..." The boot wrapper will interpret the --kernel and --initrd arguments as taking an option which is a (host system) path, and pass the tail of the string following '--' to the kernel as its command line.

24	config-default.mk: Explicitly pass -marm when we want to bui... config-default.mk: Explicitly pass -marm when we want to build ARM mode Explicitly pass -marm in the CFLAGS when we want to build in ARM mode, because some compilers will default to Thumb. This has not previously been a problem in practice because the assembler will compile in ARM mode anyway unless we told it to use Thumb mode with -Wa,-mthumb. However it does mean that we end up building boot.S with a cpp that thinks it is compiling for Thumb (and thus defines __thumb__) but an assembler that generates ARM code. Passing -marm explicitly avoids this mismatch and allows us to use the cpp preprocessor defines without fear. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
23	boot.S: Factor out kernel cmd-line from boot-loader boot.S: Factor out kernel cmd-line from boot-loader The kernel command lines are set in the Makefile and config files now anyway and depend on the board type settings in there, so there should be no need to have yet another set of ifdefs in boot.S. Signed-off-by: Christoffer Dall <c.dall@virtualopensystems.com>	Christoffer Dall	12 years ago
22	Makefile: Introduced super-simple config file Makefile: Introduced super-simple config file Config files are named config.mk. This file is added to .gitignore, but a default config file is supplied in config-default.mk. The default config file creates kernel command boot lines for NFS boots based on a script obtaining the host IP addres. Naturally users can change this to a static IP or another script if they wish. The config file lets users select a system and other config options depend on this overall setting. I am no expert on Makefiles, so there could be better ways to accomplish these things, but I think this suffices for now.

21	Makefile: Pass unknown targets through to the kernel make Makefile: Pass unknown targets through to the kernel make Add some convenience rules so we pass unknown targets through to the kernel makefile. This allows you to say 'make menuconfig' (for instance) from this directory. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
20	Makefile, boot.S: Allow kernel command line to be set in mak... Makefile, boot.S: Allow kernel command line to be set in makefile Allow the kernel command line to be set in the makefile rather than forcing the user to edit boot.S every time. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
19	Makefile: Don't require filesystem.cpio.gz if building non-i... Makefile: Don't require filesystem.cpio.gz if building non-initrd Introduce a USE_INITRD switch so we can avoid requiring the user to touch a pointless filesystem.cpio.gz if they're not using an initrd. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
18	Makefile: default ARCH to 'arm' Makefile: default ARCH to 'arm' ARCH is pretty much always going to be 'arm' so it makes more sense to default it in the makefile. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>	Peter Maydell	12 years ago
17	Makefile: export CROSS_COMPILE and ARCH Makefile: export CROSS_COMPILE and ARCH CROSS_COMPILE and ARCH are needed by the kernel makefile, so export them so they are passed down even if we're using the defaults in this makefile rather than user specified (command line or environment) settings. Signed-off-by: Peter Maydell <peter.maydelL@linaro.org>	Peter Maydell	12 years ago
