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>
2018-04-06powerpc: 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>
2017-07-08powerpc: Partialy restore core of mpc8xxChristophe Leroy
CS Systemes d'Information (CSSI) manufactures 8xx boards for critical communication systems. Those boards have been running U-Boot since 2010 and will have to be maintained until at least 2027. commit 5b8e76c35ec312a3f73126bd1a2d2c0965b98a9f ("powerpc, 8xx: remove support for 8xx") orphaned those boards by removing support for the mpc8xx CPU. This commit partially restores support for the 8xx, with the following limitations: - Restores support for MPC866 and MPC885 only - Does not restore IDE, PCMCIA, I2C, USB - Does not restore examples - Does not restore POST - Does not restore Ethernet on SCC - Does not restore console on SCC - Does not restore bedbug and kgdb support As the 866 and 885 do not support the following features, they are not restored either: - VIDEO / LCD - RTC clock The CPM uCODE patch is not restored either, because: - 866 and 885 already have support for I2C and SPI relocation without a uCODE patch - relocation of SMC, I2C or SPI is only needed for using SCCs for Ethernet or QMC The dynamic setup/calculation of clocks is removed, we expect the target being use with the clock and PLPRCR register defined in the configuration. All the clock settings for 8xx prior to 866 is removed as well as we now only support 866 and 885. This code is mature and addresses mature boards. Therefore all code enclosed in '#if 0/#endif' and '#if XX_DEBUG/#endif' is unneeded. The following files are not restored by this patch: - arch/powerpc/cpu/mpc8xx/bedbug_860.c - arch/powerpc/cpu/mpc8xx/fec.h - arch/powerpc/cpu/mpc8xx/kgdb.S - arch/powerpc/cpu/mpc8xx/plprcr_write.S - arch/powerpc/cpu/mpc8xx/scc.c - arch/powerpc/cpu/mpc8xx/upatch.c - arch/powerpc/cpu/mpc8xx/video.c - arch/powerpc/include/asm/status_led.h - arch/powerpc/lib/ide.c - arch/powerpc/lib/ide.h - doc/README.MPC866 - drivers/pcmcia/mpc8xx_pcmcia.c - drivers/rtc/mpc8xx.c - drivers/usb/gadget/mpc8xx_udc.c - drivers/video/mpc8xx_lcd.c - examples/standalone/test_burst.c - examples/standalone/test_burst.h - examples/standalone/test_burst_lib.S - examples/standalone/timer.c - include/mpc823_lcd.h - include/usb/mpc8xx_udc.h - post/cpu/mpc8xx/Makefile - post/cpu/mpc8xx/cache.c - post/cpu/mpc8xx/cache_8xx.S - post/cpu/mpc8xx/ether.c - post/cpu/mpc8xx/spr.c - post/cpu/mpc8xx/uart.c - post/cpu/mpc8xx/usb.c - post/cpu/mpc8xx/watchdog.c Some of the restored files are not located in a proper location. In order to keep traceability of the changes, they will be moved to their correct location and moved to Kconfig in a followup patch. This patch also declares CSSI as point of contact for the update of the 8xx platform, as those boards are the only ones still being maintained on the 8xx area. A later patch will add those boards to the tree. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

2016-04-08powerpc: mpc85xx: Enable pre-relocation malloc for MPC85xxmario.six@gdsys.cc
To enable DM on MPC85xx, we need pre-relocation malloc, which is implemented in this patch. We also make sure that the IVORs are always 4-aligned on e500 to prevent alignment exceptions caused by code changes in start.S.

2015-04-20powerpc/mpc85xx: Don't relocate exception vectorsScott Wood
Booke does not require exception vectors to be located at address zero. U-Boot was doing so anyway, simply because that's how it had been done on other PPC. The downside of this is that once the OS is loaded to address zero, the exception vectors have been overwritten -- which makes it difficult to diagnose a crash that happens after that point. The IVOR setup and trap entry code is simplified somewhat as a result. Also, there is no longer a need to align individual exceptions on 0x100 byte boundaries.

2014-03-07powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260Masahiro Yamada
Before this commit, CONFIG_MPC8260 and CONFIG_8260 were used mixed-up. All boards with mpc8260 cpu defined both of them: - CONFIG_MPC8260 was defined in board config headers and include/common.h - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk We do not need to have both of them. This commit keeps only CONFIG_MPC8260. This commit does: - Delete CONFIG_8260 and CONFIG_MPC8260 definition in config headers and include/common.h - Rename CONFIG_8260 to CONFIG_MPC8260 in arch/powerpc/cpu/mpc8260/config.mk. - Rename #ifdef CONFIG_8260 to #ifdef CONFIG_MPC8260 Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Wolfgang Denk <wd@denx.de>
