* x86: broadwell: Add support for SDRAM setupSimon Glass2016-03-17-0/+177
| | | | | | | | | Broadwell uses a binary blob called the memory reference code (MRC) to start up its SDRAM. This is similar to ivybridge so we can mostly use common code for running this blob. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>
* x86: broadwell: Add power-control supportSimon Glass2016-03-17-0/+129
| | | | | | | | | | Broadwell requires quite a bit of power-management setup. Add code to set this up correctly. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com> [squashed in http://patchwork.ozlabs.org/patch/598373/] Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
* x86: broadwell: Add an LPC driverSimon Glass2016-03-17-0/+32
| | | | | | | | Add a driver for the broadwell LPC (low-pin-count peripheral). This mostly uses common code. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>
* x86: broadwell: Add a pinctrl driverSimon Glass2016-03-17-0/+91
| | | | | | | | | | | GPIO pins need to be set up on start-up. Add a driver to provide this, configured from the device tree. The binding is slightly different from the existing ICH6 binding, since that is quite verbose. The new binding should be just as extensible.

* x86: Add basic support for broadwellSimon Glass2016-03-17-0/+446
This adds the broadwell architecture, with the CPU driver and some useful header files. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>
