2023-07-12mtd: rawnand: brcmnand: Fix mtd oobsizeWilliam Zhang1-2/+5
brcmnand controller can only access the flash spare area up to certain bytes based on the ECC level. It can be less than the actual flash spare area size. For example, for many NAND chip supporting ECC BCH-8, it has 226 bytes spare area. But controller can only uses 218 bytes. So brcmand driver overrides the mtd oobsize with the controller's accessible spare area size. When the nand base driver utilizes the nand_device object, it resets the oobsize back to the actual flash spare aprea size from nand_memory_organization structure and controller may not able to access all the oob area as mtd advises. This change fixes the issue by overriding the oobsize in the nand_memory_organization structure to the controller's accessible spare area size.

2023-07-12mtd: rawnand: brcmnand: Fix potential out-of-bounds access in oob writeWilliam Zhang1-2/+16
When the oob buffer length is not in multiple of words, the oob write function does out-of-bounds read on the oob source buffer at the last iteration. Fix that by always checking length limit on the oob buffer read and fill with 0xff when reaching the end of the buffer to the oob registers.

It is incorrect to calculate number of OOB bytes for ECC engine using some "already known" ECC step size (1024 bytes here). Number of such bytes for ECC engine must be whole OOB except 2 bytes for bad block marker, while proper ECC step size and strength will be selected by ECC logic.

MTD provider provides mtd_info object to mtd subsystem. With kref patch the mtd_info object can be alive after provider released mtd device. Fix calling order in _get and _put functions to allow mtd provider to safely alloc and release mtd object.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

Meson NAND controller requires 8 bytes alignment for DMA addresses, otherwise it "aligns" passed address by itself thus accessing invalid location in the provided buffer. This patch makes unaligned buffers to be reallocated to become valid.

2023-06-12block: replace fmode_t with a block-specific type for block open flagsChristoph Hellwig3-7/+6
The only overlap between the block open flags mapped into the fmode_t and other uses of fmode_t are FMODE_READ and FMODE_WRITE. Define a new blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and ->ioctl and stop abusing fmode_t.

2023-06-12block: use the holder as indication for exclusive opensChristoph Hellwig1-2/+2
The current interface for exclusive opens is rather confusing as it requires both the FMODE_EXCL flag and a holder. Remove the need to pass FMODE_EXCL and just key off the exclusive open off a non-NULL holder. For blkdev_put this requires adding the holder argument, which provides better debug checking that only the holder actually releases the hold, but at the same time allows removing the now superfluous mode argument.

2023-06-09mtd: otp: Put factory OTP/NVRAM into the entropy poolLinus Walleij1-0/+19
The factory OTP, if supported, contains factory-programmed information such as typically the serial number or production week for the chip. As this is device-unique information, submit it into the system entropy pool. This does not count as improvement of the entropy as such but in practice it makes it a bit more random to mix in these numbers. Cc: Michael Walle <[email protected]> Acked-by: Jason A.

2023-06-09mtd: chips: Use SPDX license headersLinus Walleij9-11/+15
Some of the files in mtd/chips do not have a SPDX license header, presumably because the text string "GPL'd" didn't parse with Thomas rulesets for magic license tagging. Fix this, the code is initially from RedHat which clearly targeted the Linux kernel and intended it to be GPLv2. In any case the original author appears to be David Woodhouse who can then confirm this.
