2018-04-06powerpc: mpc8xx: move watchdog into drivers/watchdogChristophe Leroy
In preparation of DM watchdog, move basic actions into drivers/watchdog Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06powerpc: mpc8xx: cleaning up watchdogChristophe Leroy
In preparation of migration to DM watchdog, clean up a bit. The 8xx watchdog really is a HW watchdog, so declare it as is then it goes through Kconfig And the watchdog reset doesn't mind getting interrupted, so no need to disable interrupts Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06powerpc: mpc8xx: refactorise reginfoChristophe Leroy
reginfo is redundant with some of the commands in immap.c, so move reginfo into that file and remove duplicated info. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06board: MCR3000: cleanup configChristophe Leroy
Some config is redundant with Kconfig. Fix it. Also remove unused configs Move SDRAM_MAX_SIZE in the only place it is used include/environment.h already defines CONFIG_ENV_SIZE from CONFIG_ENV_SECT_SIZE and defines CONFIG_ENV_ADDR as (CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET) remove BOOTARGS as bootargs is set by the different boot commands Fix CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE to be in line with CPM DPRAM organisation Remove CONFIG_SYS_GBL_DATA_SIZE, CONFIG_SYS_GBL_DATA_OFFSET and CONFIG_SYS_INIT_SP_OFFSET which are unused Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
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: redistribute data in CPM dpramChristophe Leroy
Some malloc memory is needed at startup for DM model. Lets reorganise the use of the CPM dpram. The MPC866/885 dpram, we have 8kbytes dual port RAM, which is usable as: IMMR + 0x2000..0x2800: BD/Data/Microcode IMMR + 0x2800..0x2e00: BD/Data IMMR + 0x2e00..0x3800: BD/Data/Microcode IMMR + 0x3800..0x3a00: BD/Data IMMR + 0x3a00..0x3c00: BD/Data/Microcode IMMR + 0x3c00..0x4000: Parameters for the Peripheral Controllers Lets reallocate all BDs in the 3800..3a00 area and give the full 2800..2e00 for dynamic RAM allocation including global data That way, the microcode areas remain available if needed one day.

2018-04-06powercp: mpc8xx: move commproc.hChristophe Leroy
include/commproc.h is dedicated to the 8xx, rename it cpm_8xx.h and move it into arch/powerpc/include/asm Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06powerpc: mpc8xx: Change CONFIG_8xx to CONFIG_MPC8xxChristophe Leroy
CONFIG_8xx doesn't mean much outside of arch/powerpc/ This patch renames it CONFIG_MPC8xx just like CONFIG_MPC85xx etc ... It also renames 8xx_immap.h to immap_8xx.h to be consistent with other file names. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06powerpc: mpc8xx: remove get_immr() argumentChristophe Leroy
get_immr() is always called with 0 as an argument, so it is useless. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06powerpc: mpc8xx: make get_immr() independent of CONFIG_8xxChristophe Leroy
SPRN_IMMR is defined regardless of the CPU. Therefore, there is no point in enclosing get_immr() inside a #ifdef CONFIG_8xx As it a static inline function, it will in any case only be compiled in functons using it. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06powerpc: mpc8xx: get rid of the multiple PVR_ valuesChristophe Leroy
Avoid hardcoding the PVR values in C since they are defined in processor.h At the same time, remove those multiple PVR values for 8xx and keep only one that we call PVR_8xx 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>

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>
2018-02-18fdt: Implement weak arch_fixup_fdt()Alexey Brodkin
Only ARM and in some configs MIPS really implement arch_fixup_fdt(). Others just use the same boilerplate which is not good by itself, but what's worse if we try to build with disabled CONFIG_CMD_BOOTM and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was apparently implemented in arch/xxx/lib/bootm.c. Now with weak arch_fixup_fdt() right in image-fdt.c where it is used we get both items highlighted above fixed.

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>

2017-10-02powerpc: Use asm-generic/io.hPaul Burton
Convert the powerpc architecture to make use of the new asm-generic/io.h to provide address mapping functions. As powerpc can actually perform non-identity mapping between physical & virtual addresses we can't simply make use of the generic phys_to_virt() & virt_to_phys() functions. However since map_physmem() already effectively implemented the same thing as virt_to_phys() we can simply implement virt_to_phys() instead of map_physmem() & use the generic map_physmem(). We also drop the no-op unmap_physmem(). This has only been build-tested, feedback from architecture maintainers is welcome.

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.

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.
