ftsmc020: move ftsmc020 static mem controller to driver/mtd

2011-04-27T17:38:10+00:00

Move the header file and definitions of ftsmc020
static memory control unit from a320 SoC folder to
"drivers/mtd" folder.

This change will let other SoC which also use ftsmc020
could share the same header file.

cfi_flash driver - Add delay after reset command

2011-04-21T13:51:49+00:00

I ran into a problem where the reset was failing except when I enabled
debugging support.  After talking with Garret Swalling at Spansion I
was told that the GL-N series of devices require a 500ns wait for the
reset to complete.  The below patch adds a 1us delay after all reset
commands.

cfi_flash: reverse geometry for M29W800DT parts

2011-04-21T13:51:17+00:00

The M29W800DT parts also report their geometry with the sector layout
reversed.  So add that ID to the flash_fixup_stm function.

Otherwise, we get:

NAND: rearrange ONFI revision checking, add ONFI 2.3

2011-04-15T20:53:11+00:00

This patch sync with Brian's patch on Linux in nand_flash_detect_onfi()

	commit b7b1a29d94c17e4341856381bccb4d17495bea60

	    mtd: nand: rearrange ONFI revision checking, add ONFI 2.3

	    In checking for the ONFI revision, the first conditional (for checking
	    "unsupported" ONFI) seems unnecessary.  All ONFI revisions should be
	    backwards-compatible; even if this is not the case on some newer ONFI
	    revision, it should simply fail the second version-checking if-else block
	    (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we
	    move our "unsupported" condition after having checked each bit field.

	    Also, it's simple enough to add a condition for ONFI revision 2.3. Note
	    that this does *NOT* mean we handle all new features of ONFI versions
	    above 1.0.
