* biosemu: Do not free vga_info->BIOSImage when it is 0xc0000Bin Meng2015-04-29-1/+2
| | | | | | | For x86, vga_info->BIOSImage points to 0xc0000 which cannot be freed. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Add some VESA interface debuggingSimon Glass2015-01-23-20/+141
| | | | | | Allow the supported modes to be listed when in debug mode. Signed-off-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Don't display error when emulator terminatesSimon Glass2015-01-23-1/+1
| | | | | | As it turns out this is a normal condition, so suppress the error. Signed-off-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Fix an #ifdef typo in the header fileSimon Glass2015-01-23-1/+1
| | | | | | | This stops the debug mode from working properly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* bios_emulator: Correct ordering of includesSimon Glass2014-12-13-2/+2
| | | | | | | We should include common.h before other includes. This actually causes a build error on chromebook_link. Signed-off-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Always print errors when opcode decode failsSimon Glass2014-11-25-18/+22
| | | | | | | | | This is a rare event and should not happen. When it does it is confusing to work out why. At least we should print a message. Adjust the emulator to always print decode errors to the console. Signed-off-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Add an option to enable debuggingSimon Glass2014-11-25-54/+90
| | | | | | | | | | At present there are DEBUG options spread around the place. If you enable one and not another you can end up with an emulator that does not work, since each file can have a different view of what the registers look like. To fix this, create a global CONFIG_X86EMU_DEBUG option that keeps everything consistent. Signed-off-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Allow a custom interrupt handler to be installedSimon Glass2014-11-25-0/+6
| | | | | | | Sometime we want to provide an interrupt handler for the ROM, Add a function to allow this. Signed-off-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Add vesa support and allow ROMs to be passed in as dataSimon Glass2014-11-25-58/+144
| | | | | | | | | As well as locating the ROM on the PCI bus, allow the ROM to be supplied to the emulator. Split the init up a little so that callers can supply their own interrupt routines. Also allow a vesa mode to be provided, to be selected once the BIOS run is complete. Signed-off-by: Simon Glass <sjg@chromium.org>
* bios_emulator: Allow x86 to use the emulatorSimon Glass2014-11-25-23/+23
| | | | | | | | | | | There is an implicit assumption that x86 machines want to use raw I/O in the BIOS emulator, but this should be selectable. Add an CONFIG_X86EMU_RAW_IO option to control it instead. Also fix a few bugs which cause warnings on x86 and adjust the Makefile to remove the assumption that only PowerPC uses the emulator. Signed-off-by: Simon Glass <sjg@chromium.org>
* Introduce a header file for the BIOS emulatorSimon Glass2014-11-25-51/+2
| | | | | | | We should have a public header so that users can avoid defining functions themselves. Signed-off-by: Simon Glass <sjg@chromium.org>
* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

* biosemu: include <asm/io.h> headerLinus Walleij2013-04-02-0/+4
| | | | | | | | | | | | This makes sure we have inline functions such as inb/outb that are used in these two files by including the arch-specific <asm/io.h> header. However the ARM version does not provide the accessors unless the config symbol __io is also defined so add that in front of the include. After this the bios emulator will compile on ARM systems.

* Consolidate bool typeYork Sun2013-04-01-9/+5
| | | | | | | | | | | | | 'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
