* x86: fsp: Introduce CONFIG_FSP_USE_UPD Kconfig optionBin Meng2016-01-13-9/+23
| | | | | | | | | | Not every FSP supports UPD, thus we introduce a Kconfig option CONFIG_FSP_USE_UPD and use it to wrap these common UPD handling codes in fsp_support.c. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | To support platform-specific configurations (might not always be UPD on some platform), use a better name update_fsp_configs() and accepct struct fsp_config_data as its parameter so that platform codes can handle whatever configuration data for that FSP.

* x86: fsp: Rename shared_data to fsp_config_dataBin Meng2016-01-13-12/+46
| | | | | | | | | | | | FSP has several config data like UPD, HDA verb table which can be overridden or provided by bootloader. Currently in U-Boot only UPD is handled via struct shared_data. To accommodate any platform, we rename shared_data to fsp_config_data and move the definition from common place fsp_support.h to platform-specific place fsp_configs.h.

| | | | | | | | | | | Right now i8254_init() is called from timer_init() in the tsc timer driver. But actually i8254 and tsc are completely different things. Since tsc timer has been converted to driver model, we should find a new place that is appropriate for U-Boot to call i8254_init(), which is now x86_cpu_init_f().

* x86: queensbay: Really disable IGDBin Meng2015-11-13-10/+23
| | | | | | | | | | | | | | | | | | | | | | According to Atom E6xx datasheet, setting VGA Disable (bit17) of Graphics Controller register (offset 0x50) prevents IGD (D2:F0) from reporting itself as a VGA display controller class in the PCI configuration space, and should also prevent it from responding to VGA legacy memory range and I/O addresses. However test result shows that with just VGA Disable bit set and a PCIe graphics card connected to one of the PCIe controllers on the E6xx, accessing the VGA legacy space still causes system hang. After a number of attempts, it turns out besides VGA Disable bit, the SDVO (D3:F0) device should be disabled to make it work. To simplify, use the Function Disable register (offset 0xc4) to disable both IGD (D2:F0) and SDVO (D3:F0) devices. Now these two devices will be completely disabled (invisible in the PCI configuration space) unless a system reset is performed.
