* x86: coreboot: Make SYS_CONFIG_NAME and DEFAULT_DEVICE_TREE configurableBin Meng2015-01-13-0/+13
| | | | | | | | | | | | | In theory U-Boot built for coreboot is supposed to run as a payload to be loaded by coreboot on every board that coreboot supports. The U-Boot build process uses SYS_CONFIG_NAME and DEFAULT_DEVICE_TREE which are hardcoded in board defconfig and Kconfig files. For better support of coreboot, we want to make these two options configurable so that we can easily change them during 'make menuconfig' so that the generated U-Boot image for coreboot is board configuration aware.

* x86: Hide ROM chip size when CONFIG_X86_RESET_VECTOR is not selectedBin Meng2015-01-13-0/+2
| | | | | | | | When CONFIG_X86_RESET_VECTOR is not selected, specifying the ROM chip size is meaningless, hence hide it. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Move CONFIG_X86_RESET_VECTOR and CONFIG_SYS_X86_START16 to KconfigBin Meng2015-01-13-4/+11
| | | | | | | | Convert CONFIG_X86_RESET_VECTOR and CONFIG_SYS_X86_START16 to Kconfig options so that we can remove them from board configuration file. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Allow a hardcoded TSC frequency provided by KconfigBin Meng2015-01-13-2/+26
| | | | | | | | | | | | | | By default U-Boot automatically calibrates TSC running frequency via MSR and PIT. The calibration may not work on every x86 processor, so a new Kconfig option CONFIG_TSC_CALIBRATION_BYPASS is introduced to allow bypassing the calibration and assign a hardcoded TSC frequency CONFIG_TSC_FREQ_IN_MHZ. Normally the bypass should be turned on in a simulation environment like qemu. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: coreboot: Set up timer base correctlyBin Meng2015-01-13-13/+20
| | | | | | | | | | | | | | If coreboot is built with CONFIG_COLLECT_TIMESTAMPS, use the value of base_time in coreboot's timestamp table as our timer base, otherwise TSC counter value will be used. Sometimes even coreboot is built with CONFIG_COLLECT_TIMESTAMPS, the value of base_time in the timestamp table is still zero, so we must exclude this case too (this is currently seen on booting coreboot in qemu).

| | | | | | | | | | | These two are not worth having separate inline functions as they are really simple, so drop them. Also changed 'type' parameter of fsp_get_next_hob() from u16 to uint.

* x86: Add an 'mtrr' command to list and adjust MTRRsSimon Glass2015-01-13-1/+156
| | | | | | | | | | | | | It is useful to be able to see the MTRR setup in U-Boot. Add a command to list the state of the variable MTRR registers and allow them to be changed. Update the documentation to list some of the available commands. This does not support fixed MTRRs as yet. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Bin Meng <bmeng.cn@gmail.com>
* x86: ivybridge: Update microcode early in bootSimon Glass2015-01-13-13/+40
| | | | | | | | | | | At present the normal update (which happens much later) does not work. This seems to have something to do with the 'no eviction' mode in the CAR, or at least moving the microcode update after that causes it not to work. For now, do an update early on so that it definitely works. Also refuse to continue unless the microcode update check (later in boot) is successful. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Disable CAR before relocation on platforms that need itSimon Glass2015-01-13-0/+8
| | | | | | | For platforms with CAR we should disable it before relocation. Check if this function is available and call it if so. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Add a way to turn off the CARSimon Glass2015-01-13-0/+46

* x86: Commit the current MTRRs before relocationSimon Glass2015-01-13-0/+8
| | | | | | | | Once we stop running from ROM we should set up the MTTRs to speed up execution. This is only needed for platforms that don't have an FSP. Also in the Coreboot case, the MTRRs are set up for us. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Request MTRRs for DRAM regionsSimon Glass2015-01-13-0/+10
| | | | | | | | | We should use MTRRs to speed up execution. Add a list of MTRR requests which will dealt with when we relocate and run from RAM. We set RAM as cacheable (with write-back) and registers as non-cacheable. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: board_f: Adjust x86 boot order for performanceSimon Glass2015-01-13-3/+5
| | | | | | | | For bare platforms we turn off ROM-caching before calling board_init_f_r() It is then very slow to copy U-Boot from ROM to RAM. So adjust the order so that the copying happens before we turn off ROM-caching. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Set up an MTRR for the video frame bufferSimon Glass2015-01-13-0/+7
| | | | | | | Set the frame buffer to write-combining. This makes it faster, although for scrolling write-through is even faster for U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Add support for MTRRsSimon Glass2015-01-13-101/+187
| | | | | | | | | | | | | | Memory Type Range Registers are used to tell the CPU whether memory is cacheable and if so the cache write mode to use. Clean up the existing header file to follow style, and remove the unneeded code. These can speed up booting so should be supported. Add these to global_data so they can be requested while booting. We will apply the changes during relocation (in a later commit). Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Drop support for ROM cachingSimon Glass2015-01-13-25/+0
| | | | | | | | | | This is set up along with CAR (Cache-as-RAM) anyway. When we relocate we don't really need ROM caching (we read the VGA BIOS from ROM but that is about it) Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: pci: Display vesa modes in hexSimon Glass2015-01-13-2/+2

* x86: Use cache, don't clear the display in video BIOSSimon Glass2015-01-13-3/+2
| | | | | | | There is no need to run with the cache disabled, and there is no point in clearing the display frame buffer since U-Boot does it later. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Only run the Video BIOS when video is enabledSimon Glass2015-01-13-1/+8
| | | | | | | | | | | | This takes about about 700ms on link when running natively and 900ms when running using the emulator. It is a waste of time if video is not enabled, so don't bother running the video BIOS in that case. We could add a command to run the video BIOS later when needed, but this is not considered at present. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: video: Add debug option to time the BIOS copySimon Glass2015-01-13-0/+3

* serial: ns16550: Support ns16550 compatible pci uart devicesBin Meng2015-01-13-0/+31

We can describe them in the board dts file and use it as the U-Boot serial console as specified in the chosen node 'stdout-path' property. Those pci uart devices can have their register be memory-mapped, or i/o-mapped. The driver will try to use the memory-mapped register if the reg property in the node has an entry to describe the memory-mapped register, otherwise i/o-mapped register will be used.
