If CONFIG_CMD_IMD is not set there is no imd_command_setenv in the
barebox binary that can be linked to. Although the whole imd infrastructure
will be removed by the linker later in the build process as soon as it
figures out that nothing inside barebox is using it, we still have to
provide a dummy function to keep the build going.
Fixes:
In function `imd_command': undefined reference to `imd_command_setenv'

PBL never calls start_barebox(). If it does, it is a bug.
Without this stub function, we can detect such a bug at link time.

mtd devices now have a partition parameter to create mtd partitions.
Use it to simplify the mtdparts-add script.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
The partitions parameter allows to partition a mtd device
using a standard cmdline partition description string. This
way the partitions of a mtd device can be changed at once.
The output of the string can be used to be passed to the kernel
as cmdline partition string. The partitions can also still be
changed with addpart/delpart, the partitions parameter will
be updated accordingly.

mtd_add_partition is passed a flag parameter. This has been unused
so the DEVFS_PARTITION_FIXED and DEVFS_PARTITION_READONLY were ignored.
Fix this.

mtd partitions should not conflict with each other, so forbid this.
Also add the partitions to the partitions list sorted, so that they
can be easier translated into a cmdline partition string.

This adds a function to parse a full cmdline partition string. The

The NFC command used for reading the result of a READID command to the NAND chip
reads 6 bytes (in x8 mode) or 6 words (in x16 mode with the upper bytes all
being 0). So there is no need to safe 16 bytes for later consumption.

This corresponds to commit c7f23a70635895b5125aeb5593aaf8cb44d3a088 in
the Linux kernel.
One notable difference is however that ONFI detection is allowed here
even in 16-bit mode. This is proved to work fine on an i.MX25 based
machine with a x16 NAND.

There are a few NAND commands that make the chip only respond on I/O
lines 0 to 7 even for x16 devices. READID (90h) is one such command
which was already handled fine in the driver (at least for NFC v1 and
v2). Other commands (like PARAM (ECh) to read out ONFI parameters)
however were not handled properly. Instead of adding another callback
make the read_byte callback handle the holes added by the NFC and depend
on the nand-base support to call read_byte when necessary instead of
read_buf.
This fixes reading the ONFI parameter page on an i.MX25 with an x16 NAND
and probably[1] also the result of READID on i.MX51/i.MX53 with x16
NAND.

in nand_bb_read() 'offset' contains the virtual position on the device,
but we have to test for a bad block on the raw physical position, so
use bb->offset instead of offset
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
When a block is marked bad after the bb device has been created
the real size of the bb device is smaller than the calculated size
on creation. In this case we can't rely on the upper layers anymore
that they won't pass read/write sizes in that fit into the device.

Partitions are mtd devices themselves, but the 'erasebad'
parameter is only set to the master mtd device. To allow to
erase bad blocks on partitions test the master device instead
of the partition devices.

| mtd: omap gpmc: fix ecc bytes/size
|
| The ecc bytes / size are per subpage, not per page.
|
| Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
The ecc code in omap_correct_data() expects to correct a whole page
at once, so we must tell the nand layer that we have 4 * 13 bytes of
ecc bytes and 4 * 512 bytes of ecc size. Otherwise the NAND layer will
iterate over 512 byte steps over a page and call the .correct callback
each time.
This only works for 2k pagesize and needs revisit once other page sizes
shall be supported. It would be better to tell the nand layer the real
ecc bytes (13) and ecc size (512) instead and drop the iteration in
omap_correct_bch(). However, this needs better testing so it isn't done
here now.
