2016-02-05dm: pch: Add get_io_base opBin Meng
On some newer chipset (eg: BayTrail), there is an IO base address register on the PCH device which configures the base address of a memory-mapped I/O controller. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
2016-02-05dm: pch: Add get_gpio_base opBin Meng
x86 GPIO registers are accessed via I/O port whose base address is configured in a PCI configuration register on the PCH device. Add an op get_gpio_base to get the GPIO base address from PCH.

Spell out 'sbase' to 'spi_base' so that it looks clearer. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
2016-02-05dm: pch: Remove pch_get_version opBin Meng
pch_get_version op was only used by the ich spi controller driver, and does not really provide a good identification of pch controller so far, since we see plenty of Intel PCH chipsets and one differs from another a lot, which is not simply either a PCHV_7 or PCHV_9. Now that ich spi controller driver was updated to not get such info from pch, the pch_get_version op is useless now.

2016-01-24dm: x86: Add a driver for Intel PCH7Simon Glass
At some point we may need to distinguish between different types of PCHs, but for existing supported platforms we only need to worry about version 7 and version 9 bridges. Add a driver for the PCH7. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2016-01-24dm: Expand the uclass for Platform Controller Hubs (PCH)Simon Glass
A Platform Controller Hub is an Intel concept - it is like the peripherals on an SoC and is often in a separate chip from the CPU. The chip is typically found on the first PCI bus and integrates multiple devices. We have a very simple uclass to support PCHs. Add a few operations, such as setting up the devices on the PCH and finding the SPI controller base address. Also move it into drivers/pch/ since we will be adding a few PCH drivers.
