Subject: [U-Boot] [PATCH RFC] NAND: Improve read performance from Large Page NAND devices
Date: Tue, 08 Dec 2009 15:33:45 +0000 [thread overview]
Message-ID: <4B1E71D9.6080802@ge.com> (raw)
Improve read performance from Large Page NAND devices.
This patch produces a ~31% improvement in oob_first read speed (on a
300MHz ARM9). The time for a mid-buffer 2k page read is now 293us,
6.99MB/s (was 385us, 5.31MB/s). oob_first is probably the best case
improvement.
