Subject: Fix Ymodem build when DEBUG and CONFIG_USE_TINY_PRINTF are selected
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=8140816eea9faef804a333e8416249fc57d0bedc;p=u-boot.git

Fix Ymodem build when DEBUG and CONFIG_USE_TINY_PRINTF are selected

Attempting to build with both DEBUG and CONFIG_USE_TINY_PRINTF along
with CONFIG_SPL_YMODEM_SUPPORT fails at link time:

  common/built-in.o: In function `zm_dprintf':
  common/xyzModem.c:190: undefined reference to `vsprintf'

Disable Ymodem debug if we don't have full vsprintf support.
