Re: [U-Boot] [PATCH 1/3] xilinx: zynqmp: Add new target with only qspi enabled

On 5.1.2018 11:46, Siva Durga Prasad Paladugu wrote:

This patch adds new target which is called as mini configuration with only qspi enabled. This will be used to run in system with small footprint and needs qspi support. One example of such case is that it can run from OCM and programs qspi flash in DDR less systems.

This depends on qspi driver which is not applied yet that's why I am skipping this patch.

And I have applied the rest of patches.
