2017-10-01rockchip: spl: support a 'same-as-spl'-specifier in the spl-boot-orderPhilipp Tomsich
It is often desirable to configure the spl-boot-order (i.e. the order that SPL probes devices to find the FIT image containing a full U-Boot) such that it contains 'the same device the SPL stage was booted from' early on. To support this, we introduce the 'same-as-spl' specifier for the spl-boot-order property. This commit adds: - documentation for the new board_spl_was_booted_from() function that individual SoCs/boards should provide, if they can determine where the SPL was booted from - implements the new board_spl_was_booted_from() stub function - adds support for handling the 'same-as-spl' specifier and calling into the per-SoC/per-board support code. This also updates the documentation for the 'u-boot,spl-boot-order' property. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2017-10-01rockchip: spl: add documentation for spl_node_to_boot_device()Philipp Tomsich
In the expectation that the spl-boot-order code will eventually gain use outside of mach-rockchip: let's add documentation on the spl_node_to_boot_device() function, which is likely to become a publicly exported function.

2017-08-13rockchip: spl: make spl-boot-order code reusable (split from rk3399)Philipp Tomsich
In order to reuse the support for the u-boot,spl-boot-order property from the rk3399, we split it into a reusable module that can be included by the SPL code for any of our boards. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Reviewed-by: Simon Glass <sjg@chromium.org>
