2018-11-20fdt: Fix uncompress_blob() for U-Boot properMarek Vasut
When U-Boot proper is compiled with CONFIG_MULTI_DTB_FIT and tries to call uncompress_blob(), it fails with -ENOTSUPP. This is because the full implementation of this function which includes compression is available only in SPL. In U-Boot proper or if the compression is not enabled, the blob is not compressed and thus can be passed to locate_dtb_in_fit() in fdtdec_setup() without any changes. Pass the blob without any changes if compression is not enabled instead of failing.

2018-09-10Remove <inttypes.h> includes and PRI* usages in printf() entirelyMasahiro Yamada
In int-ll64.h, we always use the following typedefs: typedef unsigned int u32; typedef unsigned long uintptr_t; typedef unsigned long long u64; This does not need to match to the compiler's <inttypes.h>. Do not include it. The use of PRI* makes the code super-ugly. You can simply use "l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

2018-09-10fdt: fix get_next_memory_node()Marek Vasut
The get_next_memory_node() always sets mem to -1 , which is incorrect, because then every iteration of memory bank parsing will start from the first memory bank instead of the previous one. On systems with 1 memory bank defined in DT and CONFIG_NR_DRAM_BANKS=4 , like ie. r8a77965-salvator-x , this will result in U-Boot incorrectly reporting four identical memory banks with the same memory configuration. Fix this by setting mem to startoffset value, which restores the behavior before the fixed patch was applied.

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>

2017-11-29spl: make CONFIG_OF_EMBED pass dts through fdtgrepGoldschmidt Simon
Building spl with CONFIG_OF_EMBED enabled results in an error message on my board: "SPL image too big". This is because the fdtgrep build step is only executed for CONFIG_OF_SEPARATE. Fix this by moving the fdtgrep build step ('cmd_fdtgreo') from scripts/Makefile.spl to dts/Makefile so that the reduced dtb is available for all kinds of spl builds. The resulting variable name for the embedded device tree blob changes, too, which is why common.h and fdtdec.c have tiny changes.

2017-11-30fdtdec: Support parsing multiple /memory nodesMarek Vasut
It is legal to have multiple /memory nodes in a device tree . Currently, fdtdec_setup_memory_size() only supports parsing the first node . This patch extends the function such that if a particular /memory node does no longer have further "reg" entries and CONFIG_NR_DRAM_BANKS still allows for more DRAM banks, the code moves on to the next memory node and checks it's "reg"s. This makes it possible to handle both systems with single memory node with multiple entries and systems with multiple memory nodes with single entry.

2017-05-09Allow boards to initialize the DT at runtime.Alex Deymo
In some boards like the Raspberry Pi the initial bootloader will pass a DT to the kernel. When using U-Boot as such kernel, the board code in U-Boot should be able to provide U-Boot with this, already assembled device tree blob. This patch introduces a new config option CONFIG_OF_BOARD to use instead of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT from a board-specific funtion instead of bundling one with U-Boot or as a separated file. This allows boards like the Raspberry Pi to reuse the device tree passed from the bootcode.bin and start.elf firmware files, including the run-time selected device tree overlays.

The fdtdec_setup_memory_banksize() function decode the memory banks (up to the CONFIG_NR_DRAM_BANKS) and populates the base address and size into the gd->bd->bi_dram array of banks.

2016-05-31mmc: tegra: add basic Tegra186 supportStephen Warren
Tegra186's MMC controller needs to be explicitly identified. Add another compatible value for it. Tegra186 will use an entirely different clock/reset control mechanism to existing chips, and will use standard clock/reset APIs rather than the existing Tegra-specific custom APIs. The driver support for that isn't ready yet, so simply disable all clock/reset usage if compiling for Tegra186. This must happen at compile time rather than run-time since the custom APIs won't even be compiled in on Tegra186. In the long term, the plan would be to convert the existing custom APIs to standard APIs and get rid of the ifdefs completely. The system's main eMMC will work without any clock/reset support, since the firmware will have already initialized the controller in order to load U-Boot. Hence the driver is useful even in this apparently crippled state. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
