So change the driver's version to have an underscore before it, just like _debug_uart_putc(). Define debug_uart_init() to call this version. Update all drivers to this new method.

efi: Add support for loading U-Boot through an EFI stub 2015-08-05T14:44:06+00:00 Simon Glass sjg@chromium.org 2015-08-04T18:33:52+00:00 476476e73b14696563524cbc2627a4c033ea64da It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.
