| * x86: Use tab instead of space to indent in PCIE_ECAM_BASEBin Meng2015-02-06-1/+1
| | | | | | | | | | | | | | | | Space is used before 'default' in PCIE_ECAM_BASE in arch/x86/Kconfig so it looks misaligned. Replace the space with tab to indent. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
| * x86: Add SD/MMC support to quark/galileoBin Meng2015-02-06-0/+11
| | | | | | | | | | | | | | | | Intel Galileo board has a microSD slot which is routed from Quark SoC SDIO controller. Enable SD/MMC support so that we can use an SD card. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
| * x86: Add SPI support to quark/galileoBin Meng2015-02-06-0/+30
| | | | | | | | | | | | | | | | | | | | The Quark SoC contains a legacy SPI controller in the legacy bridge which is ICH7 compatible. Like Tunnel Creek and BayTrail, the BIOS control register offset in the ICH SPI driver is wrong for the Quark SoC too, unprotect_spi_flash() is added to enable the flash write.

| * x86: galileo: Add GPIO supportBin Meng2015-02-06-0/+14
| | | | | | | | | | | | | | | | | | | | Quark SoC has a legacy GPIO block in the legacy bridge (D0:F31), which is just the same one found in other x86 chipset. Since we programmed the GPIO register block base address, we should be able to enable the GPIO support on Intel Galileo board.

| * x86: quark: Initialize non-standard BARsBin Meng2015-02-06-0/+78
| | | | | | | | | | | | | | | | | | Quark SoC has some non-standard BARs (excluding PCI standard BARs) which need be initialized with suggested values. This includes GPIO, WDT, RCBA, PCIe ECAM and some ACPI register block base addresses. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | For some unknown reason, the TSC calibration via PIT does not work on Quark.

| | | | | | | | | | | | | | | | | | | | | | In the Quark SoC, some chipset commands are accomplished by utilizing the internal message network within the host bridge (D0:F0). Accesses to this network are accomplished by populating the message control register (MCR), Message Control Register eXtension (MCRX) and the message data register (MDR).

| * x86: Add support for Intel Minnowboard MaxSimon Glass2015-02-06-2/+3831
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a relatively low-cost x86 board in a small form factor. The main peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800 series CPU. So far only the dual core 2GB variant is supported. This uses the existing FSP support. Binary blobs are required to make this board work. The microcode update is included as a patch (all 3000 lines of it).
