* x86: apl: Avoid accessing the PCI bus before it is probedSimon Glass2020-01-072-11/+29
| | | | | | | | The PCI bus is not actually probed by the time the ofdata_to_platdata() method is called since that happens in the uclass's post_probe() method. Update the PMC and P2SB drivers to access the bus in its probe() method. Signed-off-by: Simon Glass <sjg@chromium.org>

* x86: Move qemu CPU fixup function into its own fileSimon Glass2019-12-153-68/+79
| | | | | | | | | | | This function is specific to qemu so it seems best to keep it separate from the generic code. Move it out to a new file and update the condition to use if() instead of #ifdef Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Add a generic Intel pinctrl driverSimon Glass2019-12-152-0/+679
| | | | | | | | | | | | | | | Recent Intel SoCs share a pinctrl mechanism with many common elements. Add an implementation of this core functionality, allowing SoC-specific drivers to avoid adding common code. As well as a pinctrl driver this provides a GPIO driver based on the same code. Once other SoCs use this driver we may consider moving more properties to the device tree (e.g. the community info and pad definitions).

* x86: Separate out U-Boot and device tree in ROM imageSimon Glass2019-12-151-3/+11
| | | | | | | | | | | | | | | | | | At present binman does not support updating a device tree that is part of U-Boot (i.e u-boot.bin). Separate the entries into two so that we can get updated entry information. This makes binman_entry_find() work correctly. Do the same for SPL tool. In both cases, group the two parts into a section so that SPL symbols get the correct total size. It may be possible for binman to handle this automatically at some point, by ignoring u-boot.bin and always creating it from u-boot-nodtb.bin and u-boot.dtb Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Don't repeat microcode in U-Boot if not neededSimon Glass2019-12-151-0/+7
| | | | | | | | | At present if SPL sets up the microcode then it is still included in U-Boot as well. This is wasteful as microcode is large. Adjust the logic in the image to prevent this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* x86: Add an option to control the position of SPLSimon Glass2019-12-152-2/+7
| | | | | | | | | | | For Apollo Lake SPL is run from CAR (cache-as-RAM) which is in a different location from where SPL must be placed in ROM. In other words, although SPL runs before SDRAM is set up, it is not execute-in-place (XIP). Add a Kconfig option for the ROM position.

| | | | | | | | | | | | The existing work-around for positioning U-Boot in the ROM when it actually runs from RAM still exists and there is not obvious way to change this. Add a proper Kconfig option to handle this case. This also adds a new bool property to indicate whether CONFIG_SYS_TEXT_BASE exists.

| | | | | | | | | | | Many Intel SoCs require a FIT in order to boot properly. Add an option to include this and enable it by default.
