2014-11-21x86: Replace fill_processor_name() with cpu_get_name()Simon Glass
This implementation has a 'cpu' prefix and returns a pointer to the string, avoiding the need for copying. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Fix up some missing prototypesSimon Glass
Some functions are missing prototypes. Fix those that are specific to x86. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Use the standard arch_cpu_init() functionSimon Glass
Instead of an x86-specific cpu_init_f() function, use the normal U-Boot one for this purpose. Also remove a useless/misleading comment. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Use the standard dram_init() functionSimon Glass
Instead of having an x86-specific DRAM init function, adjust things so we can use the normal one. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2013-06-26x86: Support tracing functionSimon Glass
Some changes are needed to x86 timer functions to support tracing. Add these so that the feature works correctly. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-05-13x86: Re-enable PCAT timer 2 for beepingSimon Glass
While we don't want PCAT timers for timing, we want timer 2 so that we can still make a beep. Re-purpose the PCAT driver for this, and enable it in coreboot. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-05-13x86: Add TSC timerSimon Glass
This timer runs at a rate that can be calculated, well over 100MHz. It is ideal for accurate timing and does not need interrupt servicing. Tidy up some old broken and unneeded implementations at the same time. To provide a consistent view of boot time, we use the same time base as coreboot. Use the base timestamp supplied by coreboot as U-Boot's base time. Signed-off-by: Simon Glass <sjg@chromium.org>base Signed-off-by: Simon Glass <sjg@chromium.org>
2013-05-13x86: Implement panic output for corebootSimon Glass
panic_puts() can be called in early boot to display a message. It might help with early debugging. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Wai-Hong Tam <waihong@chromium.org>
2013-03-15x86: Use sections header to obtain link symbolsSimon Glass
These are defined in asm-generic/sections.h, so remove them from architecture-specific files. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-15Change stub example to use asm-generic/sections.hSimon Glass
We can use the declarations of __bss_start and _end from this header instead of declaring them locally. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Add an __end symbol to signal the end of the U-Boot binarySimon Glass
With this symbol we can easy append something (e.g. an FDT) to the U-Boot binary and access it from within U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>
2012-12-06x86: Remove video_init() prototype from u-boot-x86.hSimon Glass
This function is not intended to be exported from the video drivers, so remove the prototype. This fixes an error: cfb_console.c:1793:12: error: static declaration of 'video_init' follows non-static declaration Signed-off-by: Simon Glass <sjg@chromium.org>
2012-12-06x86: Add function to read time stamp counterVadim Bendebury
Put this function in the u-boot-x86.h header file. We could instead create timer.h perhaps. We support setting a base time, and reading the time relative to this base. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Stefan Reinauer <reinauer@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2012-11-30x86: Add a default implementation for cleanup_before_linux()Gabe Black
This function provides an opportunity for some last minute cleanup and reconfiguration before control is handed over to Linux. It's possible this may need to do something in the future, but for now it's left empty. It's set up as a weak symbol so it can be overridden if necessary on a case by case basis.

2012-01-04x86: Create weak init_cache() and default enable_caches() functionsGraeme Russ
-- Changes for v2: - Tweaked commit title
2012-01-04x86: Use fs for global dataGraeme Russ
Use the base address of the 'F' segment as a pointer to the global data structure. By adding the linear address (i.e. the 'D' segment address) as the first word of the global data structure, the address of the global data relative to the 'D' segment can be found simply, for example, by: fs movl 0, %eax This makes the gd 'pointer' writable prior to relocation (by reloading the Global Desctriptor Table) which brings x86 into line with all other arches NOTE: Writing to the gd 'pointer' is expensive (but we only do it twice) but using it to access global data members (read and write) is still fairly cheap -- Changes for v2: - Rebased against changes made to patch #3 - Removed extra indent - Tweaked commit message
2012-01-04x86: Simplify Flash-to-RAM code execution transitionGraeme Russ
Move the relocation offset calculation out of assembler and into C. This also paves the way for the upcoming init sequence simplification by adding the board_init_f_r flash to RAM transitional function -- Changes for v2: - Added commit message - Minor adjustment to new stack address comment

2011-08-04Convert ISO-8859 files to UTF-8Albert ARIBAUD
There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
