|
Fix auto_update for MCC200 board.
|
||||||
|
|
||||||
|
The invocation of do_auto_update() is moved to the end of the
|
||||||
|
misc_init_r() function, after the flash mappings have been
|
||||||
|
initialized. Please find attached a patch that implements that
|
||||||
|
change.
|
||||||
|
|
||||||
|
Also correct the decoding of the keypad status. With this update, the
|
||||||
|
key that will trigger the update is Column 2, Row 2.

[PATCH] nand: Fix problem with oobsize calculation
|
||||||
|
|
||||||
|
Here the description from Brian Brelsford <Brian_Brelsford@dell.com>:
|
||||||
|
|
||||||
|
The Hynix part returns a 0x1d in the 4th ID byte. The Samsung part
|
||||||
|
returns a 0x15. In the code fragment below bits [1:0] determine the
|
||||||
|
page size, it is ANDed via "(extid & 0x3)" then shifted out. The
|
||||||
|
next field is also ANDed with 0x3. However this is a one bit field
|
||||||
|
as defined in the Hynix and Samsung parts in the 4th ID byte that
|
||||||
|
determins the oobsize, not a two bit field. It works on Samsung as
|
||||||
|
bits[3:2] are 01. However for the Hynix there is a 11 in these two
|
||||||
|
bits, so the oob size gets messed up.
|
||||||
|
|
||||||
|
I checked the correct linux code and the suggested fix from Brian is
|
||||||
|
also available in the linux nand mtd driver.

[PATCH] Add DDR2 optimization code for Sequoia (440EPx) board
|
||||||
|
|
||||||
|
This code will optimize the DDR2 controller setup on a board specific
|
||||||
|
basis.
|
||||||
|
|
||||||
|
Note: This code doesn't work right now on the NAND booting image for the
|
||||||
|
Sequoia board, since it doesn't fit into the 4kBytes for the SPL image.
