260e89a6e0 mtd: core: tone down suggestion that dev.parent should be set
add_mtd_device() has a comment suggesting that the caller should have
set dev.parent. This is required to have the parent device symlink show
up in sysfs, but not for proper operation of the mtd device itself.
Currently we have five drivers registering mtd devices during module
initialization, so they don't actually provide a parent device to link
to. That means we cannot WARN_ON() here, as it would trigger false
positives.

Make the comment a bit less firm in its assertion that dev.parent should
be set.

3f08b8ba9f mtd: brcmnand: Fix pointer type-cast in brcmnand_write()
We should always type-cast pointer to "long" or "unsigned long"
because size of pointer is same as machine word size. This will
avoid pointer type-cast issues on both 32bit and 64bit systems.

This patch fixes pointer type-cast issue in brcmnand_write()
as-per above info.

192db1caa2 mtd: nand_bbt: set the smallest size of bbt table
When using nandsim to simulate a 128K block nand with `overridesize = 1',
the size of mtd device is too small (mtd_size = 4 * block_size) to get the
right length of bbt. Then when creating bbt, kzmalloc() will return
ZERO_SIZE_PTR. This causes a NULL pointer oops when scanning bbt.

This patch gives a smallest length to bbt, 1 byte, which is enough to
represent up to 4 blocks.

8e2c992b59 mtd: mtdpart: add debug prints to partition parser.
The probe of a mtd device can fail when a partition parser returns
error. The failure due to partition parsing can be quite mysterious when
multiple partitioning schemes are compiled in and any of them can fail
the probe.

Add debug prints which show what parsers were tried and what they
returned.

d54e88011d mtd: nand: lpc32xx_slc: fix calculation of timing arcs from given values
According to LPC32xx User's Manual all values measured in clock cycles
are programmable from 1 to 16 clocks (4 bits) starting from 0 in
bitfield, the current version of calculated clock cycles is too
conservative.

Correctness of 0 bitfield value (i.e. programmed 1 clock
timing) is proven with actual NAND chip devices.

In case if quotient of controller clock rate to device clock rate does
not fit into 4 bit value, choose the maximum acceptable value 0xF, which
stands for 16 clocks.

No functional change, move bitfield calculations to macro
definitions with added clock rate argument, which are in turn defined
by new common SLCTAC_CLOCKS(c, n, s) macro definition.
