2017-08-10soc/intel/apollolake: Enable UART debug controller on S3 resumeFurquan Shaikh
1. Add a new variable to GNVS to store information during S3 suspend whether UART debug controller is enabled. 2. On resume, read stored GNVS variable to decide if UART debug port controller needs to be initialized. 3. Provide helper functions required by intel/common UARRT driver for enabling controller on S3 resume.

2016-05-12soc/apollolake/uart.c: Do not NOOP .set_resources() and friendsAlexandru Gagniuc
When SOC_UART_DEBUG was not set, the boot would hang somwhere in ramstage, as evidenced by POST codes reported from the EC. This was traced to the .set_resources and .enable_resources members of the UART PCI driver being set to NOOP. Although the exact mechanism of failure is not known, this change eliminates the hang.

2016-03-10soc/intel/apollolake: Avoid UART BAR relocation at ramstageAndrey Petrov
UART bar gets overwritten during resource allocation stage. As result the serial driver ends up using stale BAR so serial output does not work. This driver simply tells resource allocator not to change BAR of UART device.
