2008-04-24[Blackfin] arch: Prevent potential Core Hang situationMichael Hennerich
If the new value written to the PLL_CTL or VR_CTL register is the same as the previous value, the PLL wake-up will occur immediately (PLL is already locked), but the core and system clock will be bypassed for the PLL_LOCKCNT duration. For this interval, code will execute at the CLKIN rate instead of at the expected CCLK rate. Software should guard against this condition by comparing the current value to the new value before writing the new value.

2007-12-24[Blackfin] arch: Fix gpio label handlingMichael Hennerich
early serial init also utilizes the peripheral request api - however at this point bfin_gpio_init didn't allocate memory for the labels. So we always have two zombies (allocated pin functions without labels) This happens before the initcalls - We now allocate memory statically. Define MAX_RESOURCES individually for each cpu.
