mtd: CFI: quirk for PF38F4476.

2009-06-05T16:51:07+00:00

This chip reports CFI 1.3, but the CFI PRI is like CFI 1.1. Add a quirk
to pass probe on this chip.

This patch depends on "MTD: CFI 1.0 and CFI 1.1"

[MTD] [CHIPS] cfi_cmdset_0001.c: Fix a bug in inval_cache_and_wait_for_operation().

2009-03-20T18:32:17+00:00

If the inval_cache_and_wait_for_operation() is re-entered by write operation when erase
operation is in progress, the chip->erase_suspended will be cleared, this cause the erase
timeo is not reset and will result time out error for erase.

[MTD] map_rom has NULL erase pointer

2009-01-11T19:56:46+00:00

Which means if inftl or similar are loaded with it (which is a dumb thing
to do admittedly) it may oops.

Closes #8108

[MTD] update internal API to support 64-bit device size

2008-12-10T13:37:21+00:00

MTD internal API presently uses 32-bit values to represent
device size.  This patch updates them to 64-bits but leaves
the external API unchanged.  Extending the external API
is a separate issue for several reasons.  First, no one
needs it at the moment.  Secondly, whether the implementation
is done with IOCTLs, sysfs or both is still debated.  Thirdly
external API changes require the internal API to be accepted
first.

Note that although the MTD API will be able to support 64-bit
device sizes, existing drivers do not and are not required
to do so, although NAND base has been updated.

In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
    	- printk message formats
    	- division and modulus of 64-bit values
    	- NAND base support
	- 32-bit local variables used by mtdpart and mtdconcat
	- naughtily assuming one structure maps to another
	in MEMERASE ioctl
