[U-Boot] [PATCH v2 0/5] x86: Early debug enhancements

This series adds a few more features to the debug UART, making it possible
to use it even when the board needs to perform additional init for the UART
to work. The debug UART is anabled on link.

Some minor PCI tidy-ups are also included.

Link currently does not boot due to lack of early malloc() memory. For now
just increase the size.

Changes in v2:
- Adjust all _debug_uart_init() declarations to be static inline
- Remove comment block since we now always enable the debug UART
- Use a tab after the 'call' instruction

Simon Glass (5):
  debug_uart: Adjust the declaration of debug_uart_init()
  debug_uart: Support board-specific UART initialisation
  debug_uart: Add an option to announce the debug UART
  x86: Init the debug UART if enabled
  x86: chromebook_link: Enable the debug UART
