[PATCH v4 0/5] Rockchip: Allow to silent TPL/SPL debug console

[Lukasz Czechowski]

Currently it is not possible to completely silent the debug console
in i.e. PX30, what might be required in some embedded devices.
Disabling DEBUG_UART results in errors, due to missing symbols.
In particular, rockchip sdram driver performs calls to debug_uart
functions (i.e. printascii), defined directly in serial driver.
This patch series fixes the dependencies in Kconfig and provides
dummy implementation of debug_uart functions that are linked in case
serial driver is not used.

changes in v2:
 - Update commit titles
 - Create separate SPL and TPL symbols for RAM_ROCKCHIP_DEBUG

changes in v3:
 - Dropped [PATCH v2 3/5] ram: rockchip: Add separate RAM_ROCKCHIP_DEBUG config for TPL/SPL
   As suggested by Kever, dependency on DEBUG_UART is sufficient and this patch
   was not needed.

changes in v4:
 - Add new patch fixing compilation warnings in lib/efi/efi_stub.c, if
   CONFIG_DEBUG_UART is not enabled. The #ifdef directive is used to
   conditionally define debug uart functions, as suggested by Quentin.
 - Fixed invalid redefinition of DEBUG_UART_FUNCS macro, and changed
   the dummy print functions implementation in debug_uart.h
