2024-04-18powerpc: 8xx: Set SDMA configuration register correclyChristophe Leroy
SDMA configuration register needs to be set up only once and doesn't belong to drivers. Also, the value to be used is different on mpc885. So do the init in cpu_init_f() with 0x40 for mpc885 and 0x1 for others. Signed-off-by: Christophe Leroy <[email protected]>

2023-04-06watchdog: mpc8xxx: Make it genericChristophe Leroy
mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same memory registers. Refactor the driver to get the register addresses from the device tree and use the compatible to know the prescale factor. Calculate the watchdog setup value from the provided timeout. Don't declare it anymore as an HW_WATCHDOG, u-boot will start servicing the watchdog early enough. On mpc8xx the watchdog configuration register is also used for configuring the bus monitor. So add it as an option to the watchdog when it is mpc8xx. When watchdog is not selected, leave the configuration of the initial SYPCR from Kconfig. Signed-off-by: Christophe Leroy <[email protected]>
2022-09-18cyclic: Use schedule() instead of WATCHDOG_RESET()Stefan Roese
Globally replace all occurances of WATCHDOG_RESET() with schedule(), which handles the HW_WATCHDOG functionality and the cyclic infrastructure.

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 <[email protected]>
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 <[email protected]>

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 <[email protected]>

As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
