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>
2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-12-04ARM: arch-meson: build memory banks using reported memory from registersNeil Armstrong
As discussed at [1], the Amlogic Meson GX SoCs can embed a BL31 firmware and a secondary BL32 firmware. Since mid-2017, the reserved memory address of the BL31 firmware was moved and grown for security reasons. But mainline U-Boot and Linux has the old address and size fixed. These SoCs have a register interface to get the two firmware reserved memory start and sizes. This patch adds a dynamic reservation of the memory zones in the device tree bootmem reserved memory zone used by the kernel in early boot. To be complete, the memory zones are also added to the EFI reserved zones. Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

2017-07-22meson-gx: reserved memory regionsxypron.glpk@gmx.de
The Odroid C2 has two GiB of memory with two reserved regions. reg = <0x0 0x0 0x0 0x1000000>; reg = <0x0 0x10000000 0x0 0x200000>; Patch bfcef28ae4cf (arm: add initial support for Amlogic Meson and ODROID-C2) provided function dram_init_banksize to reserve the first 16 MiB of RAM for firmware in function dram_init_banksize in arch/arm/mach-meson/board.c and defined CONFIG_NR_DRAM_BANKS = 1. With this patch dram_init_banksize is changed to additionally reserve the 2MiB region for the ARM Trusted Firmware (BL31). CONFIG_NR_DRAM_BANKS is set to 2.

2016-10-18arm: Disable HVC PSCI calls by defaultAlexander Graf
All systems that are running on armv8 are running bare metal with firmware that implements PSCI running in EL3. That means we don't really need to expose the hypercall variants of them. This patch leaves the code in, but makes the code explicit enough to have the compiler optimize it out. With this we don't need to worry about hvc vs smc calling convention when calling psci helper functions. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Simon Glass <sjg@chromium.org>
