2017-07-27powerpc: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-BootAndy Yan
Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

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.

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>
