powerpc: Rework interrupt_init_cpu()

2017-08-26T18:56:08Z

The function interrupt_init_cpu() is given an int return type but does not return anything but 0. Rework this to be a void function. Signed-off-by: Tom Rini Acked-by: Mario Six

powerpc, 8xx: fix missing function declarations.

2017-07-23T13:23:29Z

Add missing .h and add missing declarations in .h Declare local functions as static. Make interrupt_init_cpu function signatures consistent with how decrementer_count is declared. Based on warnings reported by 'make C=2' Signed-off-by: Christophe Leroy [trini: drop cpu_init_f as 8xx/83xx are different from the rest, rework interrupt_init_cpu/decrementer_count] Signed-off-by: Tom Rini

powerpc: Remove unneccessary #ifdefs in reginfo

2017-07-23T02:22:49Z

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.

powerpc: Partialy restore core of mpc8xx

2017-07-08T19:55:26Z

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

powerpc: remove 4xx support

2017-07-03T21:35:28Z

There was for long time no activity in the 4xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 4xx, so remove it. Signed-off-by: Heiko Schocher
