rockchip: enable TPL_SYSRESET for all rockchip SoCs

2017-09-30T22:33:35Z

With Makefiles testing for $(SPL_TPL_)SYSRESET, we need TPL_SYSRESET for do_reset() in TPL for Rockchip SoCs. References: 87c16d4 "drivers: spl: consistently use the $(SPL_TPL_) macro" Signed-off-by: Kever Yang Reviewed-by: Simon Glass Reviewed-by: Philipp Tomsich

rockchip: rk3399-puma: add boot-on regulator to override BIOS_DISABLE

2017-09-30T22:33:35Z

The (Qseven) BIOS_DISABLE signal on the RK3399-Q7 (Puma) keeps the eMMC and SPI in reset initially and we need to write a GPIO to turn them on before continuing the boot-up. This adds the DTS entries for the additional regulator and makes pinctrl and gpio3 available during SPL. It also adds a hook to the spl_board_init() to ensure that the regulator gets probed and enabled. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

rockchip: dts: rk3399-puma: add 'same-as-spl' to the front of the boot-order

2017-09-30T22:33:35Z

In the general case, we want to continue booting the full U-Boot (contained in a discoverable FIT image) from the same device the SPL stage was loaded from. This prepends the 'same-as-spl' specifier to our configurable boot-order to make this the default behaviour. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

rockchip: spl: rk3399: implement chip-specific board_spl_was_booted_from()

2017-09-30T22:33:34Z

To support the new "same-as-spl" specifier in the boot-order on the RK3399, this implements the chip-specific mapping from the information obtainable from the BROM to a OF path name. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

rockchip: spl: support a 'same-as-spl'-specifier in the spl-boot-order

2017-09-30T22:33:34Z

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 Reviewed-by: Simon Glass

rockchip: spl: add documentation for spl_node_to_boot_device()

2017-09-30T22:33:34Z

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. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

rockchip: bootrom: add definitions to retrieve BROM boot-source

2017-09-30T22:33:34Z

The Rockchip BROM allows reading where it booted from from SRAM. This adds the necessary definitions (as received from Kever) for the location of this information in the RK3399's SRAM and naming for the constants used. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

rockchip: rk3399: make spl_board_init board-specific

2017-09-30T22:33:34Z

The later-stage spl_board_init (as opposed to board_init_f) should set up board-specific details: these differ between the EVB-RK3399 and the RK3399-Q7 (Puma). This moves spl_board_init back into the individual boards and removes the unneeded functionality from Puma. Signed-off-by: Philipp Tomsich
