commit 968c4be6ac0d674749421450d9fda0d64bbb2330 Author: Marc Jones marc.jones@se-eng.com Date: Mon Dec 3 22:16:29 2012 -0700
Limit SPI device debug prints with CONFIG_DEBUG_SPI_FLASH
Fix debug printks which were not using CONFIG_DEBUG_SPI_FLASH, which would cause long delays durring boot when SPI devices were written.
