These drivers are not needed on all platforms. While they are small, it is useful in TPL to drop then. Add Kconfig control to allow this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

|
help

|
Most x86 chips include a PCH which is responsible for handling
|
|
parts of the system not handled by that CPU. It supersedes the
|
|
northbridge / southbridge architecture that was previously used. The
|
|
PCH allows for higher performance since the memory functions are
|
|
handled in the CPU.

Enable this if your SoC uses Platform Controller Hub 7 (PCH7). This
|
|
dates from about 2011 and is used on baytrail, for example. The
|
|
PCH provides access to the GPIO and SPI base addresses, among other
|
|
functions.
