2019-05-21 | ARM: renesas: Factor out DRAM setup on R-Car Gen3 | Marek Vasut | |
Pull DRAM layout configuration code into rcar-common.c instead of having it in multiple copies across board files. This poses no change for Salvator-X/XS, ULCB and Ebisu boards, however it adds a bit of extra code for Draak and Eagle boards, which now gain the capability of being passed in the DRAM layout by the ATF.

2019-05-21 | ARM: rmobile: Add recovery SPL for R-Car Gen3 | Marek Vasut | |
Build an SPL which can be started via SCIF download mode on R-Car Gen3 and allows loading and executing U-Boot uImage with the next stage code. This is also useful for starting e.g. ATF BL2, which inits the hardware and returns to the U-Boot SPL, which can then load e.g. U-Boot proper. The H3, M3-W, M3-N SoCs have plenty of SRAM for storing the U-Boot SPL while the payload, e.g. ATF BL2, executes, so there is no problem here. However, E3 and D3 have much less SRAM, hence the loader uses a trick where it copies itself beyond the area used by BL2 and executes from there. That area is 32kiB large and not enough to hold U-Boot SPL, BSS, stack and malloc area, so the later two are placed at +0x4000 offset from start of SRAM, another area not used by ATF BL2. To make things even more complicated, the SCIF loader cannot load to the upper 32kiB of the SRAM directly, hence the copying approach.

2017-11-30 | ARM: rmobile: Stop using rcar-common/common.c on Gen3 | Marek Vasut | |
Since the Gen3 clock driver now has a .remove callback, it is no longer necessary to shut the clock down before booting Linux in the arch_preboot_os hook. Stop using it and while doing so, remove all the ad-hoc config options which this hook used.
