From: Suniel Mahesh <su...@amarulasolutions.com> This patch series adds runtime detection of add-on board(ROC-RK3399-PC Mezzanine) by enabling I2C in SPL. This add on board hosts a CW2015 chip which is connected as slave to I2C2. In order to dynamically detect this add-on board at runtime, I2C2 is probed in SPL. If probe is successfull then a corresponding dtb is loaded, else regular dtb is loaded for the u-boot proper.
Patch #1 moves board initialiation code after rk3399 init is done. Patch #2 enables I2C in SPL for any add-on board detection at run time. Patch #3 adds support for add-on board run-time detection. Patch #4 drops ROC-RK3399-PC Mezzanine board as this is an add-on board, it will be detected at runtime. Patch #5 enables PCIe/M.2 and NVMe, as this add-on board has a PCIe/M.2.
