2018-04-03spl: nand: sunxi: introduce the nand_wait_cmd_fifo_empty() helperMiquel Raynal
One bit in the control registers indicates if the NAND controller is ready to receive a new command. Otherwise, the command FIFO is full and we should wait for this bit to flip. It then states that the last command has been processed and the FIFO is now free to welcome another command. Add this sanity check before starting any new command.

2018-04-03spl: nand: sunxi: introduce the nand_wait_int() helperMiquel Raynal
The pattern of polling on a status register until a bit is set or a timeout occurs is repeated multiple times in the driver. Mutualize the code by introducing the nand_wait_int() helper that does wait for the bit to flip or returns an error in case of timeout.

2018-04-03spl: nand: sunxi: fix second case of modulo by zero errorMiquel Raynal
In the nand_read_buffer() step, the seed is calculated by doing a modulo by conf->nseeds which is always zero when not using the randomizer (most of SLC NANDs). This situation turns out to lead to a run time freeze with certain toolchains. Derive this seed only when the randomizer is enabled (and conf->nseeds logically not zero), exactly like what has been done before with an identical situation, see commit ea3f750c73e3 ("nand: sunxi: Fix modulo by zero error").

2018-04-03mtd: nand: sunxi: fix ECC strength choiceMiquel Raynal
When the requested ECC strength does not exactly match the strengths supported by the ECC engine, the driver is selecting the closest strength meeting the 'selected_strength > requested_strength' constraint. Fix the fact that, in this particular case, ecc->strength value was not updated to match the 'selected_strength'. For instance, one can encounter this issue when no ECC requirement is filled in the device tree while the NAND chip minimum requirement is not a strength/step_size combo natively supported by the ECC engine.

2017-11-29mtd: nand: add generic helpers to check, match, maximize ECC settingsMasahiro Yamada
Driver are responsible for setting up ECC parameters correctly. Those include: - Check if ECC parameters specified (usually by DT) are valid - Meet the chip's ECC requirement - Maximize ECC strength if NAND_ECC_MAXIMIZE flag is set The logic can be generalized by factoring out common code. This commit adds 3 helpers to the NAND framework: nand_check_ecc_caps - Check if preset step_size and strength are valid nand_match_ecc_req - Match the chip's requirement nand_maximize_ecc - Maximize the ECC strength To use the helpers above, a driver needs to provide: - Data array of supported ECC step size and strength - A hook that calculates ECC bytes from the combination of step_size and strength.

2017-11-29mtd: nand: Add an option to maximize the ECC strengthBoris Brezillon
The generic NAND DT bindings allows one to tweak the ECC strength and step size to their need. It can be used to lower the ECC strength to match a bootloader/firmware config, but might also be used to get a better reliability. In the latter case, the user might want to use the maximum ECC strength without having to explicitly calculate the exact value (this value not only depends on the OOB size, but also on the NAND controller, and can be tricky to extract). Add a generic 'nand-ecc-maximize' DT property and the associated NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best ECC strength and step-size on their own.

Currently, nand_command(_lp) calls chip->dev_ready immediately after the address cycle because NAND_CMD_SET_FEATURES falls into default: label. No wait is needed at this point. If you see nand_onfi_set_features(), R/B# is already cared by the chip->waitfunc call.

2017-10-15mtd: nand: do not check R/B# for CMD_READID in nand_command(_lp)Masahiro Yamada
Read ID (0x90) command does not toggle the R/B# pin. Without this patch, NAND_CMD_READID falls into the default: label, then R/B# is checked by chip->dev_ready().

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
