Serial: EG20T: add PCH_UART driver (3c6a4832) · Commits · 戴 / test

UART driver of Intel EG20T(Topcliff) PCH Intel EG20T PCH is the platform controller hub that is going to be used in Intel's general embedded platform. All IO peripherals in Intel EG20T PCH are actually devices sitting on AMBA bus. Intel EG20T PCH has UART I/F. Using this I/F, it is able to access system devices connected to UART. Signed-off-by:
