* i2c: intel_i2c: SMBus driver PCI addition (e.g. BayTrail)Stefan Roese2016-08-16-26/+0
| | | | | | | | | | | | | | | | | | | | | This patch adds support for the SMBus block read/write functionality. Other protocols like the SMBus quick command need to get added if this is needed. This patch also removed the SMBus related defines from the Ivybridge pch.h header. As they are integrated in this driver and should be used from here. This change is added in this patch to avoid compile breakage to keep the source git bisectable. Tested on a congatec BayTrail board to configure the SMSC2513 USB hub.

* x86: ivybridge: Implement SDRAM initSimon Glass2014-11-21-0/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: ivybridge: Add support for early GPIO initSimon Glass2014-11-21-0/+16
| | | | | | | | | | | | | | When not relying on Coreboot for GPIO init the GPIOs must be set up correctly. This is currently done statically through a rather ugly method. As the GPIOs are figured out they can be moved to the device tree and set up as needed rather than all at the start. In this implementation, board files should call ich_gpio_set_gpio_map() before the GPIO driver is used in order to provide the GPIO information. We use the early PCI interface so that this driver can now be used before relocation. Signed-off-by: Simon Glass <sjg@chromium.org>
