This function will be needed by the upcoming Designware master SPI
driver. As the SPI master controller is held in reset by the current
Preloader implementation. So we need to release the reset for the
driver to communicate with the controller.
This function is called from arch_early_init_r() if the SPI
driver is enabled.

const void *reset = &reset_manager_base->per_mod_reset;

clrbits_le32(reset, 1 << RSTMGR_PERMODRST_SPIM0_LSB);
clrbits_le32(reset, 1 << RSTMGR_PERMODRST_SPIM1_LSB);

Actually, you can do this with one clrbits, right?
Yes, will send a follow-up patch for this.
Thanks,
