2017-03-16rockchip: rk3188: Add header files for PMU and GRFHeiko Stübner
PMU is the power management unit and GRF is the general register file. Both are heavily used in U-Boot. Add header files with register definitions. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Kever Yang <kever.yang@rock-chips.com>
2017-03-16rockchip: Move bootrom-related declarations to a headerHeiko Stübner
So far spl-boards have declared the back_to_brom() function as simple extern in the files themself. That doesn't scale well if every boards defines this on its own. Therefore move the declarations to a bootrom header. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Kever Yang <kever.yang@rock-chips.com>
2017-03-16rockchip: Move bootrom helper compilation to a hidden optionHeiko Stübner
Right now the ROCKCHIP_SPL_BACK_TO_BROM option both triggers compilation of the bootrom hook-code as well as enabling the behaviour of loading the full U-Boot via the boot. New added socs may always need the bootrom code, while still being able to decide between loading U-Boot regularly or via the bootrom separately. So move the compilation of the bootrom code to a hidden option that gets selected by ROCKCHIP_SPL_BACK_TO_BROM, but can also be selected by other parts.

The SysTick is a 24-bit down counter that is found on all ARM Cortex M3, M4, M7 devices and is always located at a fixed address. The number of reference clock ticks that correspond to 10ms is normally defined in the SysTick Calibration register's TENMS field. However, on some devices this is wrong, so this driver allows the clock rate to be defined using CONFIG_SYS_HZ_CLOCK.

2017-03-14arm: omap3: Compile clock.c with -marm option to unbreak OMAP3530Siarhei Siamashka
Boards with OMAP3530 SoC fail to boot since commit bd2c4522c26d5 ("ti: armv7: enable EXT support in SPL (using ti_armv7_common.h)") because it enabled the use of Thumb2 for the SPL. Experiments have shown that the deadlock happens in the prcm_init() function from 'arch/arm/mach-omap2/omap3/clock.c'. This patch enforces the compilation of clock.c source file in ARM mode and makes the deadlock disappear. We are yet to figure out the root cause of the problem.

2017-03-01armv5te: make 'ret lr' produce iinterworking 'bx lr'Albert ARIBAUD
Current ARM assembler helper for the 'return to caller' pseudo-instruction turns 'ret lr' into 'mov pc, lr' for ARMv5TE. This causes the core to remain in its current ARM state even when the routine doing the 'ret' was called from Thumb-1 state, triggering an undefined instruction exception. This causes early run-time failures in all boards compiled using the Thumb-1 instruction set (for instance the Open-RD family). ARMv5TE supports 'bx lr' which properly implements interworking and thus correctly returns to Thumb-1 state from ARM state. This change makes 'ret lr' turn into 'bx lr' for ARMv5TE.

For LD11 and LD20 SoCs, the RST_n pin is asserted by default. If the EXT_CSD[162], bit[1:0] (RST_n_ENABLE) is fused, the eMMC device would stay in the reset state until its RST_n pin is deasserted by software.
