2018-07-30dm: Change CMD_DM enablingMichal Simek
CMD_DM is used for debug purpose and it shouldn't be enabled by default via Kconfig. Unfortunately this is in the tree for quite a long time that's why solution is to use imply DM for all targets which are enabling DM.

2018-06-19common: Fix cpu nr type which is always unsigned typeMichal Simek
cpu_cmd() is reading cpu number via simple_strtoul() which is always unsigned type. Platform code implementations are not expecting that nr can be negative and there is not checking in the code for that too. This patch is using u32 type for cpu number to make sure that platform code get proper value range. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-08net: Move enetaddr env access code to env config instead of net configAlex Kiernan
In order that we can use eth_env_* even when CONFIG_NET isn't set, move these functions to environment code from net code. This fixes failures such as: board/ti/am335x/built-in.o: In function `board_late_init': board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr' u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr' which caters for use cases such as: commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment variable") when Ethernet is required in Linux, but not U-Boot.

2018-04-06powerpc: mpc8xx: initialisation of initial RAMChristophe Leroy
u-boot requires some RAM at startup, to store global data structure. RAM is also needed when we migrate to DM for some initial malloc This patch implements the proper init of that RAM by calling board_init_f_alloc_reserve() and board_init_f_init_reserve() Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

2018-04-06powerpc: mpc8xx: harmonise initialisation of the immap local pointerChristophe Leroy
In most places, immap local pointer is defined as immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR; In a few places, it is defined as immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000); This patch replaces the few of the latest form by the other one. The two are fully equivalent since SPRN_IMMR is set with CONFIG_SYS_IMMR very early in start.S Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

2018-01-10drivers/misc: Share qbman init between archsAhmed Mansour
This patch adds changes necessary to move functionality present in PowerPC folders with ARM architectures that have DPAA1 QBMan hardware - Create new board/freescale/common/fsl_portals.c to house shared device tree fixups for DPAA1 devices with ARM and PowerPC cores - Add new header file to top includes directory to allow files in both architectures to grab the function prototypes - Port inhibit_portals() from PowerPC to ARM. This function is used in setup to disable interrupts on all QMan and BMan portals. It is needed because the interrupts are enabled by default for all portals including unused/uninitialised portals. When the kernel attempts to go to deep sleep the unused portals prevent it from doing so Signed-off-by: Ahmed Mansour <ahmed.mansour@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

2017-07-22powerpc: Remove unneccessary #ifdefs in reginfoChristophe Leroy
reginfo command is calling mpc8xx_reginfo(), mpc85xx_reginfo() or mpc86xx_reginfo() based on CONFIG_ symbol. As those 3 functions can't me defined at the same time, let's rename them print_reginfo() to avoid the #ifdefs The name is kept generic as it is not at all dependent on powerpc arch and any other arch could want to also print such information. In addition, as the Makefile compiles cmd/reginfo.c only when CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD definition inside a #ifdef CONFIG_CMD_REGINFO Lets all remove the #ifdefs around the U_BOOT_CMD as this file is only compiled when CONFIG_CMD_REGINFO is defined Finally, this is a PowerPC-only command, disable it on a number of non-PowerPC platforms.
