2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass
These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

2019-11-16ARM: rmobile: Temporarily disable PCI dma-ranges updateMarek Vasut
According to discussion in the Linux PCI list [1], the dma-ranges should be continuous and describe the entire inbound window which the controller can address and not take into account the possible DRAM holes. Temporarily disable this code which updates the dma-ranges until this meaning is sorted out.

2019-10-08spl: Allow tiny printf() to be controlled in SPL and TPLSimon Glass
At present there is only one control for this and it is used for both SPL and TPL. But SPL might have a lot more space than TPL so the extra cost of a full printf() might be acceptable. Split the option into two, providing separate SPL and TPL controls. The TPL setting defaults to the same as SPL.

2019-07-13configs: Make USE_TINY_PRINTF depend on SPL||TPL and be defaultTom Rini
The USE_TINY_PRINTF symbol only changes things within SPL and TPL builds, so make it depend on that support. Next, make it default as within these cases we should rarely have need of more advanced print formats outside of the debug context. To do this, in a few cases we need to correct our Kconfig dependencies as we had cases of non-SPL targets select'ing this symbol. Finally, in the case of a few boards we really do need the full printf functionality. Signed-off-by: Tom Rini <trini@konsulko.com>
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.

Add board code and DTs for Renesas RZ/A1 SoC-based GR-Peach, which is a cheap development platform with RZ/A1H SoC. The DTs are imported from Linux 5.0.11, commit d5a2675b207d . Currently supported are UART, ethernet and RPC SPI. The board can be booted from RPC SPI by writing the u-boot.bin binary to the beginning of the SPI NOR, e.g. using the "sf" command. The board can also be booted via JTAG by setting text base to 0x20020000, loading u-boot.bin there via JTAG and executing it from that address.

Patch "ARM: rmobile: Mark 4-64GiB as DRAM on Gen3" marked the entire 64bit DRAM space as cachable. On CortexA57, this might result in odd side effects, where the CPU tries to prefetch from those areas and if there is no DRAM backing them, CPU bus hang can happen. This patch fixes it by generating the mem_map structure based on the actual memory layout obtained from the DT, thus not marking areas without any DRAM behind them as cachable.

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A.

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>
