Will Deacon 5cb843ca0f ARM: realview: ensure visibility of writes during reset ... The various reset routines in mach-realview rely on an FPGA to power-cycle the board after writing some magic runes to memory-mapped registers. This patch adds a dsb() following the writes, so that they become visible before we mdelay(1000) in the arch_reset code. Without this patch, the timeout would expire sporadically, causing the reset to fail. Signed-off-by: Will Deacon <will.deacon@arm.com>		2011-08-12 15:40:57 +01:00
