2023-08-18mtd: rawnand: qcom: Do not override the error no of submit_descs()Manivannan Sadhasivam1-2/+2
Just use the error no returned by submit_descs() instead of overriding it with -EIO.

2023-08-18mtd: rawnand: qcom: Unmap sg_list and free desc within submic_descs()Manivannan Sadhasivam1-45/+20
There are two types of dma descriptors being used in this driver allocated by, prepare_bam_async_desc() and prep_adm_dma_desc() helper functions. These functions map and prepare the descriptors to be used for dma transfers. And all the descriptors are submitted inside the submit_descs() function. Once the transfer completion happens, those descriptors should be unmapped and freed as a part of cleanup. Currently, free_descs() function is doing the said cleanup of descriptors. But the callers of submit_descs() are required to call free_descs() in both the success and error cases. Since there are no other transactions need to be done after submit_descs(), let's just move the contents of free_descs() inside submit_descs() itself. This makes sure that the cleanup is handled within the submit_descs() thereby offloading the cleanup part from callers. While at it, let's also rename the return variable from "r" to "ret".

The naddrs variable is initialized but not used. Fixing this could have been a matter of dropping the variable, but the right way to do it looks a bit more complex: we can avoid useless writes to the q_op structure by using it. In practice we could even have possible out-of-bound bugs with the existing implementation. Let's fix all that by just performing the right number of assignments in the addr{1,2}_reg fields.

2023-07-28mtd: rawnand: qcom: Early structure initializationMiquel Raynal1-7/+5
Instead of allocating a structure on the stack with random data and then expect the callee to perform the initialization (which is, in general, error prone), prefer zeroing the structure explicitly at allocation and provide the already zeroed area, so no explicit memset operation is needed. It is probably safer to do so, so we limit the timeframe when dirty data could actually be accessed by mistake.

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.
