[MTD][NOR] Add physical address to point() method

2008-05-01T17:59:11+00:00

Adding the ability to get a physical address from point() in addition
to virtual address.  This physical address is required for XIP of
userspace code from flash.

[MTD] [NOR] Fix Intel CFI driver for collie flash

2008-04-23T00:32:12+00:00

collie seems to contain LH28F640BF flash chips. According to
http://sharp-world.com/products/device/flash/pdf/*FUM00701*@E.pdf
(page 83) if they have 0x51 of Extended Query Table (number of hardware
partitions) set to zero, they have a single fixed partition.
This patch makes those chips work.

[MTD] [NOR] Fixup for incorrect CFI data in Spansion S29GL064/32N flash chips

2008-04-22T20:17:27+00:00

This is a known erratum confirmed by Spansion.  I have an errata document,
but I can't find a link to it anywhere on their site to include here.

Some of the S29GL064N chips report 64 sectors when they should report 128,
and some of S29GL032N chips report 127 sectors when they should report 63.

Note that when the chip dies are fixed by Spansion, they will still have
the same id.  The fix is done in such a way that it won't affect corrected
chips.

The fixups use the extended id made available by a previous patch.  Without
that, virtually all newer AMD/Spansion chips will have the same ID (0x227e)
and it's not possible to apply the fixup to the correct chips.

[MTD] [NOR] Read extended device ID from AMD/Spansion CFI flash chips

2008-04-22T20:16:09+00:00

AMD/Spansion use a device id of 0x7e to indicate an extended device is
present at offset 0xe and 0xf in the query data.

I've verified with Spansion that all their chips (mfr == 0x01) with an id
of 0x7e use it to indicate an extended id is present.  What's more, there
are no chips with a NON-extended id that is the same as a different chip's
extended id.  In other words, when the extended ID is present, one can
replace the normal id with the extended id without losing any information.
Which is what I've done.

[MTD] XIP: Use generic xip_iprefetch() instead of asm volatile (...)

2008-04-22T18:47:42+00:00

Untested, but shouldn't break anything... Makes MTD_XIP arch
independent. I guess this is why xip_iprefetch() was made for.
