[PATCH 0/5] Enable I2C in SPL, support runtime detection of add-on board

[sunil at amarulasolutions.com]

From: Suniel Mahesh <sunil at 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.
