of_match_device can return NULL if there is no matching device. Avoid a potential NULL pointer dereference by checking for the return value and passing the error upstream. Signed-off-by:

The generic layout for BBT markers will most likely overlap with our ECC bytes in the OOB, so move the BBT markers outside the OOB area. Signed-off-by:

The boot ROM of the JZ4725B SoC expects a specific OOB layout on the NAND, so we use it unconditionally in the ingenic-nand driver. Also add the jz4725b-bch driver to support the JZ4725B-specific BCH hardware. Signed-off-by:

Add support for probing the ingenic-nand driver on the JZ4740 SoC from Ingenic, and the jz4740-ecc driver to support the JZ4740-specific ECC hardware. Signed-off-by:

Use the 'ecc-engine' standard property instead of the custom 'ingenic,bch-controller' custom property, which is now deprecated. Signed-off-by:
-
Paul Cercueil authored
The ingenic-nand driver uses an API provided by the jz4780-bch driver. This makes it difficult to support other SoCs in the jz4780-bch driver. To work around this, we separate the API functions from the SoC-specific code, so that these API functions are SoC-agnostic. Signed-off-by:

The jz4780_bch_init name was confusing, as it suggested that its content should be executed once at init time, whereas what the function really does is reset the hardware for a new ECC operation. Signed-off-by:

Paul Cercueil authored
The jz4780_nand driver will be modified to handle all the Ingenic JZ47xx SoCs that the upstream Linux kernel supports (JZ4740, JZ4725B, JZ4770, JZ4780), so it makes sense to rename it. Signed-off-by:

meson_nfc_dma_buffer_setup() is called with the "info" buffer which is allocated a few lines before using kzalloc(). If meson_nfc_dma_buffer_setup() fails we need to free the allocated "info" buffer instead of only freeing it upon success.

kzalloc() can return NULL if memory could not be allocated. Check the return value of the kzalloc() call in meson_nfc_read_buf() to make it consistent with other memory allocations within the meson_nand driver.

The sam9x60 board defines the CCFG_EBICSA register under SFR, and not as a MATRIX register, as previous boards do. NAND Flash I/Os are connected to D16–D23, thus SFR_CCFG_EBICSA.NFD0_ON_D16 is set to 1. Signed-off-by:

Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file. Factor out the duplicated include directives to scripts/Makefile.asm-generic so that no architecture would opt out of the mandatory-y mechanism. um is not forced to include mandatory-y since it is a very exceptional case which does not support UAPI.

During a simple no-op (nothing changed) build I saw 39 invocations of the C compiler with the argument "-print-file-name=include". We don't need to call the C compiler 39 times for this--one time will suffice. Let's change NOSTDINC_FLAGS to a simply expanded variable to avoid this since there doesn't appear to be any reason it should be recursively expanded. On my build this shaved ~400 ms off my "no-op" build. Note that the recursive expansion seems to date back to the (really old) commit e8f5bdb0 ("[PATCH] Makefile include path ordering"). It's a little unclear to me if the point of that patch was to switch the variable to be recursively expanded (which it did) or to avoid directly assigning to NOSTDINC_FLAGS (AKA to switch to +=) because someone else (out of tree?) was setting it. I presume later since if the only goal was to switch to recursive expansion the patch would have just removed the ":". Signed-off-by:
