v3: Fixed problem with CFG vs CONFIG_SYS in board/ads5121/ads5121.c v2: Reworked MPC5121 NAND driver. Attempted to address all the problems listed by Scott Wood. Driver is now board independent. Will still need more work to be SOC independent. Driver for the NAND controller on MPC5121. This driver has been tested on ADS5121 rev4 / MPC5121e rev2 only which has the following configuration: 2K page size 8 bit device width This should work on other boards with MPC5121 rev2 silicon with little or no change to the driver. Various vintages of this controller exist on some iMX parts. Getting it to work on an iMX with the same controller version should be fairly easy. More work if it is an iMX with a different version on the controller. This controller treats 2K pages as 4 512 byte pages and the hw ecc is over the combined 512 byte main area and the first 7 bytes of the spare area. The hw ecc is stored in the last 9 bytes of the spare area. This all means the the spare area can not be written separately from the main. This means unmodified JFFS2 will not work.

Here it is, patches on the way. It's very simple. Just an environment variable, but it should be enough to do what we need currently. I should write some documentation though.

[U-Boot] [PATCH] 85xx: Add P2020DS support
by Kumar Gala 02 Jun '09

02 Jun '09

From: Srikanth Srinivasan <srikanth.srinivasan(a)freescale.com> The patch adds support for P2020DS reference platform. DDR3 interface uses hard-coded initialization rather than SPD for now and was tested at 667Mhz. Some PIXIS register definitions and associated code sections need to be fixed. TSEC1/2/3, NOR flash, MAC/SYS ID EEPROM, PCIE1/2/3 are all tested under u-boot.

[U-Boot] [PATCH] 85xx: Fix the clock adjust of mpc8569mds board
by Dave Liu 02 Jun '09

Currently the clk_adj is 6 (3/4 cycle), The settings will cause the DDR controller hang at the data init. Change the clk_adj from 6 to 4 (1/2 cycle), make the memory system stable.

In chatting w/Wolfgang on IRC he felt that we should maintain the highlevel picking a board implies ARCH and other settings. However this seems like a lot of boards in one list.. To get a rough order of magnitude MAKEALL is ~880 lines. How can we reduce this to make it a bit more manageable? - k

[U-Boot] [PATCH] mtd: nand: new base driver for memory mapped nand devices
by Mike Frysinger 29 May '09

29 May '09

The BF537-STAMP Blackfin board had a driver for working with NAND devices that are simply memory mapped. Since there is nothing Blackfin specific about this, generalize the driver a bit so that everyone can leverage it.
