From: Sourav Poddar sourav.poddar@ti.com
The ePOS EVM and EVM SK have QSPI as an option to boot. Add a qspiboot target that utilizes QSPI for env and so forth as an example of best practices. As QSPI is booted from directly we need to chang CONFIG_SYS_TEXT_BASE.
Note that on ePOS EVM the QSPI and NAND are mutually exclusive choices we need to handle that elsewhere, once NAND support is also added.
