* x86: Use struct mrc_region to describe a mrc regionBin Meng2015-10-21-1/+1
| | | | | | | | | | | | | | | | Currently struct fmap_entry is used to describe a mrc region. However this structure contains some other fields that are not related to mrc cache and causes confusion. Besides, it does not include a base address field to store SPI flash's base address. Instead in the mrccache.c it tries to use CONFIG_ROM_SIZE to calculate the SPI flash base address, which unfortunately is not 100% correct as CONFIG_ROM_SIZE may not match the whole SPI flash size. Define a new struct mrc_region and use it instead. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

* Kill unneeded #include <linux/kconfig.h>Masahiro Yamada2015-07-27-1/+0
| | | | | | | | | | | | | | | | Because the top-level Makefile forces all the source files to include include/linux/kconfig.h (see the UBOOTINCLUDE define), these includes are redundant. By the way, there are exceptions for the statement above; host programs. In fact, host tools in U-Boot depend on a particular board configuration, although I think they should not. So, some files still include <linux/config.h> to work around build errors on host tools.

* x86: Add multi-processor initSimon Glass2015-04-30-2/+3
| | | | | | | | | Most modern x86 CPUs include more than one CPU core. The OS normally requires that these 'Application Processors' (APs) be brought up by the boot loader.

* x86: chromebook_link: dts: Add PCH and LPC devicesSimon Glass2015-04-18-2/+13
| | | | | | | | | | | | The PCH (Platform Controller Hub) is on the PCI bus, so show it as such. The LPC (Low Pin Count) and SPI bus are inside the PCH, so put these in the right place also. Rename the compatible strings to be more descriptive since this board is the only user. Once we are using driver model fully on x86, these will be dropped. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: x86: Add a uclass for a Platform Controller HubSimon Glass2015-04-18-9/+0
| | | | | | | | | Add a simple uclass for this chip which is often found in x86 systems where the CPU is a separate device. The device can have children, so make it scan the device tree for these. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: x86: spi: Convert ICH SPI driver to driver modelSimon Glass2015-04-18-10/+14
| | | | | | | | | | | | 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>
* dm: x86: pci: Convert chromebook_link to use driver model for pciSimon Glass2015-04-18-65/+57
| | | | | | | | | | | | | | | | Move chromebook_link over to driver model for PCI. This involves: - adding a uclass for platform controller hub - removing most of the existing PCI driver - adjusting how CPU init works to use driver model instead - rename the lpc compatible string (it will be removed later) This does not really take advantage of driver model fully, but it does work. Furture work will improve the code structure to remove many of the explicit calls to init the board. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Split up arch_cpu_init()Simon Glass2015-04-16-0/+8

* x86: Add a x86_ prefix to the x86-specific PCI functionsSimon Glass2015-04-16-163/+166
| | | | | | | | | | | | These functions currently use a generic name, but they are for x86 only. This may introduce confusion and prevents U-Boot from using these names more widely. In fact it should be possible to remove these at some point and use generic functions, but for now, rename them.

* x86: Implement a cache for Memory Reference Code parametersSimon Glass2015-01-24-0/+410
| | | | | | | | | | | The memory reference code takes a very long time to 'train' its SDRAM interface, around half a second. To avoid this delay on every boot we can store the parameters from the last training sessions to speed up the next. Add an implementation of this, storing the training data in CMOS RAM and SPI flash. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: ivybridge: Update microcode early in bootSimon Glass2015-01-13-10/+34
| | | | | | | | | | | 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: ivybridge: Add a way to turn off the CARSimon Glass2015-01-13-0/+46
| | | | | | | Cache-as-RAM should be turned off when we relocate since we want to run from RAM. Add a function to perform this task. 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: 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 Glass2015-01-13-6/+6
| | | | | | | | | | | | | | 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: 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>

| | | | | | | | | | | | | There are several problems in the code. The device tree decode is incorrect in ways that are masked due to a matching bug. Both are fixed. Also microcode_read_rev() should be inline and called before the microcode is written. Note: microcode writing does not work correctly on ivybridge for me. Further work is needed to resolve this.
