f3c89d9228 mtd: Handle 29LV800BT
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.

07b2c5c0e5 mtd/cfi: add support for SST 4KB sector granularity
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.

81316a902a mtd/cfi_flash: fix write problems for Numonyx P33/30 32 MBit flashs
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.

ca5def3f30 cfi_flash: Simplify dynamic flash bank number detection
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.

On platforms with multiple NOR chips, currently only the first one

problem by using different names for the NOR "mtd devices".

It also changes the name of the NOR MTD device from "cfi-mtd" to

09ce9921a7 flash/cfi_flash: Use virtual sector start address, not phys
include/flash.h was commented to say that the address in
flash_info->start was a physical address.  However, from u-boot's
point of view, and looking at most flash code, it makes more
sense for this to be a virtual address.  So I corrected the
comment to indicate that this was a virtual address.

The only flash driver that was actually treating the address
as physical was the mtd/cfi_flash driver.  However, this code
was using it inconsistently as it actually directly dereferenced
the "start" element, while it used map_physmem to get a
virtual address in other places.  I changed this driver so
that the code which initializes the info->start field calls
map_physmem to get a virtual address, eliminating the need for
further map_physmem calls.  The code is now consistent.

The *only* place a physical address should be used is when defining the
flash banks list that is used to initialize the flash_info struct,
usually found in the board config file.

2662b40cac * Changes/fixes for drivers/cfi_flash.c:
- Add Intel legacy lock/unlock support to common CFI driver

    On some Intel flash's (e.g. Intel J3) legacy unlocking is
    supported, meaning that unlocking of one sector will unlock
    all sectors of this bank. Using this feature, unlocking
    of all sectors upon startup (via env var "unlock=yes") will
    get much faster.

  - Fixed problem with multiple reads of envronment variable
    "unlock" as pointed out by Reinhard Arlt & Anders Larsen.

  - Removed unwanted linefeeds from "protect" command when
    CFG_FLASH_PROTECTION is enabled.

  - Changed p3p400 board to use CFG_FLASH_PROTECTION
