Board gets reset when performing burst read/write operations. On the other hand, no such behaviour is observed on small size operations.
In Linux, readl_poll_timeout API already adds delay of 1us which is further skipped in U-boot. Hence, use new "readl_poll_sleep_timeout" API which adds delay alongwith timeout functionality.
Signed-off-by: Kuldeep Singh kuldeep.singh@nxp.com --- v3: -Reword commit message and use new API instead of adding delay. -Depends on: a) https://patchwork.ozlabs.org/project/uboot/patch/20200425110354.12381-2-jaga... b) https://patchwork.ozlabs.org/project/uboot/patch/20200425110354.12381-3-jaga...
v2: -Add comments above udelay(1) change.
