> MEM API
> To support the SPI MEM API, instead of modifying the existing U-Boot
> driver, this patch adds a port of the existing Linux driver.
> This also has the advantage that porting changes and fixes from Linux will
> be easier.
> Porting of driver left most of the functions unchanged while few of the
> changes are:
> -Remove lock(mutexes) and irq handler as u-boot is a single core execution.
> -Remove invalid masterid as it was required specially for multicore
> execution in LS2088ARDB which is not the case in u-boot.
> -Remove clock support as changing spi speed is not supported in uboot and
> nor in linux.
> Currently tested on LS1088ARDB, LS1012ARDB, LS1046ARDB, LS1046AFRWY,
> LS1043AQDS, LS1021ATWR, LS2088ARDB, I.MX6ULL EVK.

> v5: Remove compilation warning/error. No other change.

> v3: Use 1k size to make driver independent of flash size.
> v2: Merge removal of old driver and addition of new driver in single patch
A gentle ping.
Could you please let me know if there's any dependency on my side.
