mtd: Handle 29LV800BT

2014-11-19T07:48:41+00:00

The device id makes u-boot think that this chip needs
cfi_reverse_geometry(), which is not the case.
Add it to jedec_flash, so it is handled properly.

mtd/cfi: add support for SST 4KB sector granularity

2013-01-10T13:39:13+00:00

Add support for SST 4KB sector granularity.

Many recent SST flashes, i.e. SST39VF3201B and similar of this family
are declared CFI-conformant from SST. They support CFI query, but implement
2 different sector sizes in the same memory: a 64KB sector (they call it
"block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector",
erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh
of cfi query struct, detects a number of secotrs for the 4KB granularity
(flinfo shows it).

For all other aspects, they are CFI compliant, so, as Linux do, i think
it's a good idea to handle these chips in the CFI driver, with a fixup
to allow 4KB granularity, as should be expected, instead of 64KB.

cfi: Make the flash erase and write operations abortable

2012-09-03T09:24:27+00:00

Check for ctrlc() in operations that take time and loop over the flash
addresses.

In netconsole, tstc() is expensive.  Only check once in a while to not
slow down the operation significantly.

mtd/cfi_flash: fix write problems for Numonyx P33/30 32 MBit flashs

2012-08-13T12:34:44+00:00

commit 54652991
Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips

fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads
to problems for smaller versions of this chip e.g. the 32Mbit version
with deviceid 0x16 on mgcoge. So move the code for this work around to
an own function and check previously manufacturer id and device id to
not break other flashes which don't need this work around.

collect code which protects default sectors in a function, called

cfi_flash: Simplify dynamic flash bank number detection

2010-09-20T13:08:51+00:00

This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By
moving these optional variables and defines into the common code, board
specific code is minimized. Currently only the following board use
this feature:

APC405, IDS8247, TQM834x

And IDS8247 doesn't seem to really need this feature, since its not
updating the bank number variable at all. So this patch removes the
definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port.

This new framework will be used by the upcoming lwmon5 update as well.
