kconfig: add board Kconfig and defconfig files This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

powerpc: Partialy restore core of mpc8xx 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.

powerpc: introduce CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLD When flush_cache() is called during boot on our ~7M kernel image, the hundreds of thousands of WATCHDOG_RESET calls end up adding significantly to boottime. Flushing a single cache line doesn't take many microseconds, so doing these calls for every cache line is complete overkill. The generic watchdog_reset() provided by wdt-uclass.c actually contains some rate-limiting logic that should in theory mitigate this, but alas, that rate-limiting must be disabled on powerpc because of its get_timer() implementation - get_timer() works just fine until interrupts are disabled, but it just so happens that the "big" flush_cache() call happens in the part of bootm where interrupts are indeed disabled. [1] [2] [3] I have checked with objdump that the generated code doesn't change when this option is left at its default value of 0: gcc is smart enough to see that the ">=" comparison is tautologically true, hence all assignments to "flushed" are eliminated as dead stores. On our board, setting the option to something like 65536 ends up reducing total boottime by about 0.8 seconds.
