mtd: nand: atmel: use another functions to set gpio value

2017-04-13T20:44:49+00:00

Because there isn't the implementation of gpio_set/get_value()
and gpio_set/get_value() after the at91 gpio driver is converted
to support the driver model, use at91_set_gpio_value() and
at91_get_gpio_value()

mtd: nand: am335x_spl_bch: Incorporate tWB delay in nand_command function

2017-04-09T01:34:50+00:00

Various commands to NAND flash results in the NAND flash becoming busy.
For those commands the SoC should wait until the NAND indicates it is
no longer busy before sending further commands. However, there is a delay
between the time the SoC sends its last command and when the NAND flash
sets its Ready/Busy Pin. This delay (tWB) must be respected or the SoC may
falsely assume the flash is ready when in reality it just hasn't had enough
time to indicate that it is busy.

Properly delaying by tWB is already done for nand_command/nand_command_lp
in nand_base.c including the version of it in the Linux kernel. Therefore,
this patch brings the handling of tWB delay inline to nand_base.c

nand: sunxi: Add options for the SPL NAND configuration

2017-04-07T05:53:46+00:00

The SPL image needs to be built with a different ECC configuration than the
U-Boot binary.

Add Kconfig options with defaults to provide a value that should work for
anyone, but is still configurable if needs be.

mtd: sunxi: Change U-Boot offset

2017-04-07T05:53:46+00:00

The default U-Boot offset for the Allwinner SoCs was set to 32kB.

This was probably to try to maintain some compatibility with the current
image that we build for the MMC where the U-Boot binary is also located at
a 32kB offset.

However, this causes a number of issues. The first one is that it prevents
us from using a backup SPL entirely, which is troublesome in case where the
first would be corrupt (especially on MLC which have a higher number of
bitflips).

We also cannot use the original MMC image on the NAND, because we need to
prepare the SPL image to include the ECCs and randomizer settings, which
reduces the interest of setting it at that particular offset.

It also prevents us from upgrading and flashing the U-Boot and SPLs
independantly, since it's very likely that it will fall in the same erase
block.

Since that default wasn't used by any board, change it for 8MB, which will
be in an erase block of its own, all the erase blocks being multiple of
two. The highest erase block size we encountered is 4MB, which means that
in this particular setup, the first and second erase blocks will be for the
SPL and its backup, and the third for U-Boot.

nand: sunxi: Fix modulo by zero error

2017-04-07T05:53:45+00:00

When trying to autodetect the ECC and randomization configurations, the
driver starts with a randomization disabled and no seeds.

In this case, the number of seeds is obviously 0, and the randomize boolean
is set to false.

However, the logic that retrieves the seed for a given page offset will
blindly use the number of seeds, without testing if the randomization is
enabled, basically doing a modulo by 0.

As it turns out, the libgcc in the common toolchain returns 0 here, which
was our expected value in such a case, and why we would not detect it.
However, U-Boot's libgcc will for some reason return from the function
instead, resulting in an error to load the U-Boot binary in the SPL.
