2017-04-08mtd: nand: am335x_spl_bch: Incorporate tWB delay in nand_command functionCooper Jr., Franklin
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 Signed-off-by: Franklin S Cooper Jr <fcooper@ti.com> [trini: Reformat comments slightly] Signed-off-by: Tom Rini <trini@konsulko.com>

2017-04-07mtd: sunxi: Change U-Boot offsetMaxime Ripard
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.

2017-04-07nand: sunxi: Fix modulo by zero errorMaxime Ripard
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.

As a consequence the function remains in the while(1) loop with 'writelen' becoming 0xffffffff and iterating until the watchdog timeout triggers.
