SPDX: Convert all of our single license tags to Linux Kernel style 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>

arm, ppc: rework environment variables for keymile boards This patch reworks all headerfiles for keymile boards. Furthermore the environment variables are refactored. Changes: - introduce km-powerpc.h file and extract ppc specific parts to it - move ARM specific options and vaiables to km_arm.h - sort the environment variables to logical groups - enhance the description of the environment variables - remove KM specific HW key and board id from kernel command line Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Kim Phillips <kim.phillips@freescale.com> cc: Kim Phillips <kim.phillips@freescale.com> cc: Wolfgang Denk <wd@denx.de> cc: Valentin Longchamp <valentin.longchamp@keymile.com>

arm: Remove use of board_early_init_r/last_stage_init() These boards define CONFIG_LAST_STAGE_INIT and CONFIG_BOARD_EARLY_INIT_R but these options are not available on ARM. Move them into the powerpc common file instead. This change affects: km_kirkwood_pci, mgcoge3un, kmnusa, kmcoge5un, km_kirkwood and portl2. Signed-off-by: Simon Glass <sjg@chromium.org>

km: adapt defines and variables for new memory layout Due to increasing kernel image sizes we get problems when decompressing the kernel image. To fix this we need to change the addresses where we load and where we extract the kernel. Also we need to adapt the address where to load the CRAMFS image and where to load the DTB file. While at it also harmonize all boards for PPC and ARM to have the same values. Also we add a new variable "env_version", so that the userspace is able to detect if this is a u-boot binary with updated values or not.

km-powerpc: define CONFIG_PRAM to protect PHRAM and PNVRAM When u-boot initializes the RAM (early in boot) it looks for the "pram" env variable to know which is area it cannot use. If the "pram" env variable is not found, the default CONFIG_PRAM value is used. This value used to be 0 (no protection at all). This patch sets it to a value that covers PHRAM and PNVRAM that must be protected in our case.

km/common: rework and simplify default environment This is the second step to simplify and decrease the default environment for the keymile boards. The release usecase formaly used to set the production environment was removed and the default configuration is now the production environment. So the formar environment variable "release" which has done a lot of things in the past, simply erase the current environment and do a reset which forces u-boot to setup the default environment again.

arm/km: define fdt_high env variable and allow backwards compatibility Add set_fdthigh subcommand to "subbootcmds" (release) so to set "fdt_high" This is necessary on Kirkwood so that the FDT does not get relocated above the memory limit that the kernel cannot access (that is the memory part reserved for the switch). This was tested on NUSA1, where it is necessary, and on ETER1, where it doesn't seem to hurt. We want the scripts to also work with older versions of u-boot, where: a) set_fdthigh is not defined (will be default env for newer u-boots) b) the fdt will not be available For this reason, we use "set_fdthigh" to tell whether we are running a newer (FDT-aware) u-boot or not. So if "set_fdthigh" runs successfully or arch != arm we try loading the fdt; otherwise we proceed normally. Notice how, contrary to release mode, set_fdthigh will _not_ be part of subbootcmds for develop and ramfs, but will be executed as part of "tftpfdt". Since this is only needed for kirkwood cards, and it prevents the kernel from booting on QorIQ (though it seemed to work on ETER1), we change its definition in the default env for powerpc so that the value is only set on ARM.

km: update the boot script to check for a DTB If a DTB is found with cramfsls, the bootscript continues as expected. If none is found, the cramfsloadfdt and boot subbootcmds are updated to not load the DTB from cramfs and not pass it to the kernel. The kernel thus must have an appended DTB otherwise the boot will fail. This is required for the km_kirkwood boards that must support .esw where the DTB sometimes is appended (for backwards compatibility) and sometimes is passed correctly (as we do now for all newer boards).
