Enable LZO compression of the multi-DTB fitImages, since the U-Boot with multiple DTs enabled is becoming quite large and the DTs can be well compressed.

2018-11-02ARM: rmobile: Generate fitting mem_map on Gen3Marek Vasut2-1/+91
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.

2018-05-10SPDX: Convert a few files that were missed beforeTom Rini1-2/+1

2018-05-07arm: v7: Kconfig: Rename CPU_V7 as CPU_V7ALokesh Vutla1-1/+1
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. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

2018-05-07regmap: clean up regmap allocationMasahiro Yamada1-1/+1
Putting zero length array at the end of struct is a common technique to embed arbitrary length of members. There is no good reason to let regmap_alloc_count() branch by "if (count <= 1)". As far as I understood the code, regmap->base is an alias of regmap->ranges[0].start, but it is not helpful but make the code just ugly. Rename regmap_alloc_count() to regmap_alloc() because the _count suffix seems pointless.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini32-70/+37
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>

2018-04-11ARM: rmobile: Add JTAG recovery support for M2 PorterMarek Vasut1-0/+24
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>

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.
