commit cc0f10446f58a75c3fc81de0128d01956e9e9b18 Author: Vadim Bendebury vbendeb@chromium.org Date: Wed Apr 23 14:26:01 2014 -0700
ipq8064/storm: UART enable and various fixes
The original patch from chromium was a bit of a mishmash. Between that, rebasing and using the coreboot.org UART infrastructure, the patch has changed a bit from the original. It seems reasonable to keep these changes together. - build in the ipq UART and turn on bootblock console - sets LPAE and ROM header address - adds cpd.c to storm
The original commit: ipq8064: make UART driver work in bootblock
This patch it the last one in the chain adapting the ipq9064 UART driver for use in coreboot. A new config option (CONSOLE_SERIAL_IPQ806X) is being introduced to control inclusion of the driver.
The previously introduced uart_wrapper.c is now included in the build to provide the console driver structure used by ramstage.
Necessary configuration options are added to allow use of UART in the bootblock.
