the following patch was just integrated into master: commit 361cd8153d3426f2ba4f65ccb396e8e20e738068 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Mon Aug 12 23:29:57 2013 +0300
console: Squelch console output from AP CPUs in romstage
Add Kconfig option SQUELCH_EARLY_SMP and have it enabled by default.
Console drivers have unpredictable results if multiple threads attempt to share same resources without spinlock. Serial UARTs have not had huge problems, only distorted output, but those relying on cache-as-ram (CBMEM and usbdebug) may require this.
