* 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: Always print errors when opcode decode failsSimon Glass2014-11-25-17/+17
| | | | | | | | | 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 Glass2014-11-25-27/+27
| | | | | | | | | | 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/+5
| | | | | | | 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: Allow x86 to use the emulatorSimon Glass2014-11-25-5/+3
| | | | | | | | | | | 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.

* Consolidate bool typeYork Sun2013-04-01-1/+1
| | | | | | | | | | | | | '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.

* Add abs() macro to return absolute valueSimon Glass2012-05-15-5/+0
| | | | | | | | | This macro is generally useful to make it available in common. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Tom Rini <trini@ti.com> Acked-by: Mike Frysinger <vapier@gentoo.org>

* Replace space and tab checks with isblankJason Hobbs2011-10-17-3/+4

* Leave x86emu op code tables in default sectionEd Swarthout2009-10-12-14/+8
| | | | | | | | Forcing the tables into got2 caused extra relocation when using -mrelocatable. This patch requires any board defining CONFIG_BIOSEMU to use -mrelocatable. Signed-off-by: Ed Swarthout <Ed.Swarthout@freescale.com> Acked-by: Jin Zhengxiong <Jason.Jin@freescale.com>

* Fix the function conflict in x86emu when DEBUG is onJason Jin2008-10-17-3/+3
| | | | | | | | | The function parse_line() in common/main.c was exposed globally by commit 6636b62a6efc7f14e6e788788631ae7a7fca4537, Result in conflict with the same name funciton in drivers/bios_emulator/x86emu/debug.c when define the DEBUG.
