2019-05-21ARM: renesas: Factor out DRAM setup on R-Car Gen3Marek 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.

2019-05-21ARM: rmobile: Add recovery SPL for R-Car Gen3Marek 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.

2018-10-18ARM: rmobile: Fix module clock controls refer status on Gen3Hiroyuki Yokoyama
When referring to the MSTPSR register, it contains the clock status of SYS, RT, SECURE, and controlling SMSTPCR using this value has the problem of being affected by the RT and SECURE status.This patch changes the reference register to SMSTPCR.

This code is unnecessary, because these registers are set by the initial program loader (IPL). Signed-off-by: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com>

This patch renames the routine fdtdec_setup_memory_size() to fdtdec_setup_mem_size_base() as it now fills the mem base as well along with size.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
