size_t read_len should be declared at the beginning of this function.

Do you need this functionality in SPL ? If so, you might need a matching Kconfig
SPL_SPI_STACKED_PARALLEL symbol .
This functionality is not needed for SPL.
So SPL does use SPI NOR in non-stacked/parallel mode, and U-Boot does
use it in stacked/parallel mode ? Doesn't that pose a problem ?

FLASH_BAR and stacked parallel configuration doesn’t depend on each other.
Is the use of BAR register and stacked/parallel mode mutually exclusive
or can they be used together ?
