mtd: rawnand: stm32_fmc2: get resources from parent node

2020-08-13T07:53:34Z

FMC2 EBI support has been added. Common resources (registers base address and clock) can now be shared between the 2 drivers using "st,stm32mp1-fmc2-nfc" compatible string. It means that the common resources should now be found in the parent device when EBI node is available. Signed-off-by: Christophe Kerello Reviewed-by: Patrice Chotard

mtd: rawnand: stm32_fmc2: use clrsetbits_le32

This patch uses clrsetbits_le32 function instead of multiple instructions. Signed-off-by: Christophe Kerello Reviewed-by: Patrice Chotard

mtd: rawnand: stm32_fmc2: use FIELD_PREP/FIELD_GET macros

2020-08-13T07:53:34Z

This patch removes custom macros and uses FIELD_PREP and FIELD_GET macros. Signed-off-by: Christophe Kerello Reviewed-by: Patrice Chotard

mtd: rawnand: stm32_fmc2: cosmetic change to use nfc instead of fmc2 where relevant

2020-08-13T07:53:34Z

This patch renames functions and local variables. This cleanup is done to get all functions starting by stm32_fmc2_nfc in the FMC2 raw NAND driver when all functions will start by stm32_fmc2_ebi in the FMC2 EBI driver. Signed-off-by: Christophe Kerello Reviewed-by: Patrice Chotard

mtd: rawnand: stm32_fmc2: use FMC2_TIMEOUT_5S for timeouts

2020-08-13T07:53:34Z

FMC2_TIMEOUT_5S will be used each time that we need to wait. It was seen, during stress tests in an overloaded system, that we could be close to 1 second, even if we never met this value. To be safe, FMC2_TIMEOUT_MS is set to 5 seconds. Signed-off-by: Christophe Kerello Reviewed-by: Patrice Chotard

mtd: rawnand: stm32_fmc2: remove useless inline comments

2020-08-13T07:53:34Z

Remove inline comments that are useless since function label are self explanatory. Signed-off-by: Christophe Kerello Reviewed-by: Patrice Chotard

Fix corner case in bad block table handling.

2020-08-05T03:30:02Z

In the unlikely event that both blocks 10 and 11 are marked as bad (on a 32 bit machine), then the process of marking block 10 as bad stomps on cached entry for block 11. There are (of course) other examples. Signed-off-by: Patrick Doyle Reviewed-by: Richard Weinberger

nand: Drop dm.h header file

2020-08-04T02:19:54Z

This header file should not be included in other header files. Remove it and use a forward declaration instead. Signed-off-by: Simon Glass

mtd: spi-nor: Tidy up error handling / debug code

2020-08-04T02:19:54Z

The -ENODEV error value in spi_nor_read_id() is incorrect since there clearly is a device - it just cannot be supported. Use -ENOMEDIUM instead which has the virtue of being less common. Fix the return value in spi_nor_scan(). Also there are a few printf() statements which should be debug() since they bloat the code with unused strings at present. Fix those while here.
