[PATCH v3 0/4] 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.

Lukasz Czechowski (4):
  debug_uart: Replace debug functions with dummies if CONFIG_DEBUG_UART
    is not set
  ram: rockchip: Fix dependency of RAM_ROCKCHIP_DEBUG
  rockchip: px30: Weaken dependency TPL/SPL serial
  rockchip: px30: Fix hard dependency to DEBUG_UART_BOARD_INIT
