Hi all, these patches implement GPMI NAND xload mechanism for i.MX6 SoCs. The xload from GPMI NAND is needed in case board wants to boot from internal SRAM (limited in size) and then load remaining barebox image from NAND. The usual use-case for xload mechanism is board DRAM size auto-detection and runtime configuration without the need for separate DCD tables for each SoM variant. In our case patches were required to support DRAM size auto-detection on Phytec's phycard-imx6 SoM with 1GiB and 2GiB DRAM variants. Thus we decided to submit example implementation on the mentioned board as RFC patch that will follow these patch series. Nonetheless, the majority of work was already provided by Sascha Hauer, but his patches were in WIP stage and not found in the mainline. We added missing parts for detecting NAND's page and oob size necessary for initial FCB page reading, etc. We hope patches spawn ideas for future implementations and work!
