This patch series makes u-boot spinand driver almost the same as spinand
driver from linux-6.16-rc6. This provides the following improvements:
* it becomes easy to port changes from linux kernel
* more flash is supported
* spi drivers can accelerate flash reading/writing using spi-mem dirmap API
* continuous reading mode was supported
* OTP support was added
* add support of special data recovery reading (for some flashes)
* bugfixes
* other minor improvements
The following linux kernel driver features was not implemented
* support of different ECC engines
* per operation spi bus frequency
The patchset also includes fixes for continuous reading mode.
The similar patches were sent to upstream linux kernel.
Changes v2:
* update patch description
* add fixes for continuous reading mode
