* mtd: resync with Linux-3.7.1Sergey Lapin2013-05-31-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

| | | | | Micron nand flash needs a reset before a read command is issued. The current mpc5121_nfc driver ignores the reset command.
* nand/mpc512x: Add MPC512x NAND support (NFC)Stefan Roese2009-06-12-0/+692
This patch adds NAND Flash Controller driver for MPC5121 revision 2. All device features, except hardware ECC and power management, are supported. This NFC driver replaces the one orignally posted by John Rigby: "[PATCH] Freescale NFC NAND driver" It's a port of the Linux driver version posted by Piotr Ziecik a few weeks ago. Using this driver has the following advantages (from my point of view): - Compatibility with the Linux NAND driver (e.g. ECC usage) - Better code quality in general - Resulting U-Boot image is a bit smaller (approx. 3k) - Better to sync with newer Linux driver versions The only disadvantage I can see, is that HW-ECC is not supported right now. But this could be added later (e.g. port from Linux driver after it's supported there). Using HW-ECC on the MCP5121 NFC has a general problem because of the ECC usage in the spare area. This collides with JFFS2 for example.
