Updating the spi-qpic-snand driver with the latest patches sent upstream and remove custom patches. These patches add error handling fixes, use of right read location in read ops, removal of unused variable, ability to read user config and nand chip requirements, and support for 8bits ECC strength. Tested on: Gl.iNet GL-B3000 & Linksys MR5500, MX2000, MX5500, SPNMX56 Signed-off-by: George Moussalem <george.moussalem@outlook.com> Link: https://github.com/openwrt/openwrt/pull/18723 Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] spi: spi-qpic-snand: use kmalloc() for OOB buffer allocation
|
|
|
|
The qcom_spi_ecc_init_ctx_pipelined() function allocates zeroed
|
|
memory for the OOB buffer, then it fills the buffer with '0xff'
|
|
bytes right after the allocation. In this case zeroing the memory
|
|
during allocation is superfluous, so use kmalloc() instead of
|
|
kzalloc() to avoid that.
