2024-03-02ARM: renesas: Rename rmobile.h to renesas.hMarek Vasut
Rename rmobile.h to renesas.h because all the chips are made by Renesas, while only a subset of them is from the R-Mobile line. Use the following command to perform the rename: " $ git grep -l 'include.*rmobile.h' | \ xargs -I {} sed -i '/include.*rmobile.h/ s@rmobile.h@renesas.h@g' {} " Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> Reviewed-by: Paul Barker <paul.barker.ct@bp.renesas.com>
2024-01-27ARM: renesas: Drop include common.hMarek Vasut
The header file is not necessary in either of those files, remove it as common.h is going away. Include missing asm/arch/rmobile.h in board/renesas/rcar-common/v3-common.c to prevent build failure of r8a77970_eagle r8a779a0_falcon r8a77980_v3hsk and r8a77970_v3msk . Include missing asm/u-boot.h in falcon.c and grpeach.c to fix build failure due to missing definition of struct bd_info . Include errno.h in grpeach.c to fix build error due to missing definition of EINVAL.

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler
Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler <hws@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

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>
2018-04-13ARM: rmobile: Convert TPL to SPLMarek Vasut
There is currently no use for building the SPL anymore, since the SPI loader can easily be replaced by TPL and TPL does load U-Boot directly. Upgrade TPL to SPL and replace what used to be SPL with it. This way we build the U-Boot sources only twice, not thrice.

2018-04-11ARM: rmobile: Add JTAG recovery support for M2 PorterMarek Vasut
Add JTAG recovery support into the M2 Porter TPL. This allows the TPL to be loaded over JTAG, initialize the system, wait for the JTAG debugger to load U-Boot image into RAM and then resume and start U-Boot from RAM. The procedure is as follows: 1) Load u-boot-tpl.bin to 0xe6300000 2) Write magic number 0x1337c0de to 0xe6300020 TPL checks for this particular magic and starts JTAG recovery if this number is present. This is not present by default. 3) Start U-Boot TPL from 0xe6300000 4) Wait for a message from TPL on UART indicating JTAG boot: "JTAG boot detected!" 5) Halt the system in JTAG debugger 6) Load U-Boot image (u-boot.img) to 0x4fffffc0 7) Write magic number 0xb33fc0de to 0xe6300024 TPL checks for this particular magic to verify that the U-Boot image was loaded into DRAM by the JTAG debugger. 8) Resume the system in JTAG debugger Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-04-11ARM: rmobile: Add TPL support on R8A7791 M2 PorterMarek Vasut
Add and enable TPL on M2 Porter. The TPL must fit into 16 kiB due to the Gen2 BootROM restriction. The TPL is running from MERAM and is capable of performing the initial initialization of PFC, Clock, GPIO, LBSC, DBSC and QSPI NOR. DBSC is responsible for bringing up the DDR DRAM access. The TPL is capable of loading the next stage, U-Boot, from either SPI NOR or UART as a fallback. If either does provide a valid U-Boot uImage, the system stops, which allows the operator to load U-Boot ie. via JTAG and start it manually.
