* x86: Kconfig: Divide the target selection to vendor/modelBin Meng2015-04-29-79/+13
| | | | | | | | | | Let arch/x86/Kconfig prompt board vendor first, then select the board model under that vendor. This way arch/x86/Kconfig only needs concern board vendor and leave the supported target list to board/<vendor>/Kconfig.

* x86: Support platform PIRQ routingBin Meng2015-04-29-0/+31
| | | | | | | | | | | | | | | On x86 boards, platform chipset receives up to four different interrupt signals from PCI devices (INTA/B/C/D), which in turn will be routed to chipset internal PIRQ lines then routed to 8259 PIC finally if configuring the whole system to work under the so-called PIC mode (in contrast to symmetric IO mode which uses IOAPIC). We add two major APIs to aid this, one for routing PIRQ and the other one for generating a PIRQ routing table. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

* dm: select CONFIG_DM* optionsMasahiro Yamada2015-04-18-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As mentioned in the previous commit, adding default values in each Kconfig causes problems because it does not co-exist with the "depends on" syntax. (Please note this is not a bug of Kconfig.) We should not do so unless we have a special reason. Actually, for CONFIG_DM*, we have no good reason to do so. Generally, CONFIG_DM is not a user-configurable option. Once we convert a driver into Driver Model, the board only works with Driver Model, i.e. CONFIG_DM must be always enabled for that board. So, using "select DM" is more suitable rather than allowing users to modify it. Another good thing is, Kconfig warns unmet dependencies for "select" syntax, so we easily notice bugs. Actually, CONFIG_DM and other related options have been added without consistency: some into arch/*/Kconfig, some into board/*/Kconfig, and some into configs/*_defconfig. This commit prefers "select" and cleans up the following issues. [1] Never use "CONFIG_DM=n" in defconfig files It is really rare to add "CONFIG_FOO=n" to disable CONFIG options. It is more common to use "# CONFIG_FOO is not set". But here, we do not even have to do it. Less than half of OMAP3 boards have been converted to Driver Model. Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is weird. Instead, add "select DM" only to appropriate boards, which eventually eliminates "CONFIG_DM=n", etc. [2] Delete redundant CONFIGs Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again in configs/sandbox_defconfig. Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and defines it also in omap3_beagle_defconfig and devkit8000_defconfig. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* dm: x86: spi: Convert ICH SPI driver to driver modelSimon Glass2015-04-18-0/+9
| | | | | | | | | | | | Convert this driver over to use driver model. Since all x86 platforms use it, move x86 to use driver model for SPI and SPI flash. Adjust all dependent code and remove the old x86 spi_init() function. Note that this does not make full use of the new PCI uclass as yet. We still scan the bus looking for the device. It should move to finding its details in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Add support for panther (Asus Chromebox)Simon Glass2015-04-16-0/+16
| | | | | | | | | | | | | | | | | | | | Support running U-Boot as a coreboot payload. Tested peripherals include: - Video (HDMI and DisplayPort) - SATA disk - Gigabit Ethernet - SPI flash USB3 does not work. This may be a problem with the USB3 PCI driver or something in the USB3 stack and has not been investigated So far this is disabled. The SD card slot also does not work. For video, coreboot will need to run the OPROM to set this up. With this board, bare support (running without coreboot) is not available as yet. Signed-off-by: Simon Glass <sjg@chromium.org>
* malloc_f: enable SYS_MALLOC_F by default if DM is onMasahiro Yamada2015-03-28-3/+0
| | | | | | | | | | | | | | This option has a bool type, not hex. Fix it and enable it if CONFIG_DM is on because Driver Model always requires malloc memory. Devices are scanned twice, before/after relocation. CONFIG_SYS_MALLOC_F should be enabled to use malloc memory before relocation. As it is board-independent, handle it globally.

* x86: Add support for Intel Minnowboard MaxSimon Glass2015-02-06-0/+15
| | | | | | | | | | | | | | This is a relatively low-cost x86 board in a small form factor. The main peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800 series CPU. So far only the dual core 2GB variant is supported. This uses the existing FSP support. Binary blobs are required to make this board work. The microcode update is included as a patch (all 3000 lines of it).

* x86: Allow a hardcoded TSC frequency provided by KconfigBin Meng2015-01-13-0/+20
| | | | | | | | | | | | | | 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.

* x86: Rename chromebook-x86 to corebootSimon Glass2014-11-21-1/+1
| | | | | | | | | | | | | Rename this vendor since it is intended to be used on any platform where coreboot runs at reset and then loads U-Boot. So far it is only tested on link. When other boards are supported it is likely that we will need to move to multiple board names, all under the 'coreboot' vendor. So while it would be possible to remove the vendor for now, that would be short-sighted. Suggested-by: Bin Meng <bmeng.cn@gmail.com> Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Implement SDRAM initSimon Glass2014-11-21-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement SDRAM init using the Memory Reference Code (mrc.bin) provided in the board directory and the SDRAM SPD information in the device tree. This also needs the Intel Management Engine (me.bin) to work. Binary blobs everywhere: so far we have MRC, ME and microcode. SDRAM init works by setting up various parameters and calling the MRC. This in turn does some sort of magic to work out how much memory there is and the timing parameters to use. It also sets up the DRAM controllers. When the MRC returns, we use the information it provides to map out the available memory in U-Boot. U-Boot normally moves itself to the top of RAM. On x86 the RAM is not generally contiguous, and anyway some RAM may be above 4GB which doesn't work in 32-bit mode. So we relocate to the top of the largest block of RAM we can find below 4GB. Memory above 4GB is accessible with special functions (see physmem). It would be possible to build U-Boot in 64-bit mode but this wouldn't necessarily provide any more memory, since the largest block is often below 4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit kernels directly so this does not pose a limitation in that area. Also there are probably parts of U-Boot that will not work correctly in 64-bit mode. The MRC is one. There is some work remaining in this area. Since memory init is very slow (over 500ms) it is possible to save the parameters in SPI flash to speed it up next time. Suspend/resume support is not fully implemented, or at least it is not efficient. With this patch, link boots to a prompt. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: chromebook_link: Implement CAR support (cache as RAM)Simon Glass2014-11-21-0/+16

* x86: Build a .rom file which can be flashed to an x86 machineSimon Glass2014-11-21-0/+13
| | | | | | | | | | | | On x86 machines U-Boot needs to be added to a large ROM image which is then flashed onto the target board. The ROM has a particular format so it makes sense for U-Boot to build this image automatically. Unfortunately it relies on binary blobs so we cannot require this for the default build as yet. Create a u-boot.rom output file for this purpose. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Add chromebook_link boardSimon Glass2014-11-21-0/+23
| | | | | | | | | | | | This board is a 'bare' version of the existing 'link 'board. It does not require coreboot to run, but is intended to start directly from the reset vector. This initial commit has place holders for a wide range of features. These will be added in follow-on patches and series. So far it cannot be booted as there is no ROM image produced, but it does build without errors. Signed-off-by: Simon Glass <sjg@chromium.org>

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+18
This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.
