[U-Boot] [PATCH 1/3] xpedite5200, 5370: Use buffered NOR flash writes
From: Peter Tyser ptyser@xes-inc.com
Buffered writes are possible on the XPedite5200 and XPedite5370 and greatly improve NOR flash write speeds
Signed-off-by: Peter Tyser ptyser@xes-inc.com --- I miscalculated the merge window close time... I hope to slip these last 3 trivial changes in the upcoming release if possible.
Thanks, Peter
