From 36d375faf5cff98e8dca32aabbbb1ec6036437dd Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Sun, 31 Aug 2008 18:24:24 +0200 Subject: avr32: Use board_postclk_init instead of gclk_init Replace the avr32-specific gclk_init() board hook with the standard board_postclk_init() hook which is supposed to run at the same point during initialization. Provide a dummy weak alias for boards not implementing this hook. The cost of this is: - 2 bytes for the dummy function (retal 0) - 2 bytes for each unnecessary function call (short rcall) which is a pretty small price to pay for avoiding lots of #ifdef clutter. In this particular case, all boards probably end up slightly smaller because we avoid the conditional checking if the gclk_init symbol is NULL.
