Subject: sunxi: SPL: add FIT config selector for Pine64 boards
X-Git-Tag: v2017.07-rc1~193^2~8
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=9ea3c35a32f1a89a86945e3c541a085df9195701;p=u-boot

sunxi: SPL: add FIT config selector for Pine64 boards

For a board or platform to support FIT loading in the SPL, it has to
provide a board_fit_config_name_match() routine, which helps to select
one of possibly multiple DTBs contained in a FIT image.
Provide a simple function which chooses the DT name U-Boot was
configured with.
If the DT name is one of the two Pine64 versions, determine the exact
model by checking the DRAM size.
