Revision 011788907ba955f87875fcfb4914881b28f7f99d authored by Thomas Petazzoni on 12 June 2014, 15:09:32 UTC, committed by Jason Cooper on 30 June 2014, 17:38:43 UTC
Commit 497a92308af8e9385fa3d135f7f416a997e4b93b ("ARM: mvebu: implement L2/PCIe deadlock workaround") introduced some logic in coherency.c to adjust the PL310 cache controller Device Tree node of Armada 375 and Armada 38x platform to include the 'arm,io-coherent' property if the system is running with hardware I/O coherency enabled. However, with the L2CC driver cleanup done by Russell King, the initialization of the L2CC driver has been moved earlier, and is now part of the init_IRQ() ARM function in arch/arm/kernel/irq.c. Therefore, calling coherency_init() in ->init_time() is now too late, as the Device Tree property gets added too late (after the L2CC driver has been initialized). In order to fix this, this commit removes the ->init_time() callback use in board-v7.c and replaces it with an ->init_irq() callback. We therefore no longer use the default ->init_irq() callback, but we now use the default ->init_time() callback. In this newly introduced ->init_irq() callback, we call irqchip_init() which is the default behavior when ->init_irq() isn't defined, and then do the initialization related to the coherency: SCU, coherency fabric, and mvebu-mbus (which is needed to start secondary CPUs).
