2017-03-14armv7m: Add SysTick timer driverPhil Edworthy
The SysTick is a 24-bit down counter that is found on all ARM Cortex M3, M4, M7 devices and is always located at a fixed address. The number of reference clock ticks that correspond to 10ms is normally defined in the SysTick Calibration register's TENMS field. However, on some devices this is wrong, so this driver allows the clock rate to be defined using CONFIG_SYS_HZ_CLOCK.

2017-03-14armv8: ls2080a: Drop early MMU for SPL buildYork Sun
Early MMU improves performance especially on emulators. However, the early MMU is left enabled after the first stage of SPL boot. Instead of flushing D-cache and dealing with re-enabling MMU for the second stage U-Boot, disabling it for SPL build simplifies the process. The performance penalty is unnoticeable on the real hardware. As of now, SPL boot is not supported by existing emulators. So this should have no impact on emulators.

2017-03-14armv8: layerscape: Rewrite memory reservationYork Sun
For ARMv8 Layerscape SoCs, secure memory and MC memorey are reserved at the end of DDR. DDR is spit into two or three banks. This patch reverts commit aabd7ddb and simplifies the calculation of reserved memory, and moves the code into common SoC file. Secure memory is carved out first. DDR bank size is reduced. Reserved memory is then allocated on the top of available memory. U-Boot still has access to reserved memory as data transferring is needed. Device tree is fixed with reduced memory size to hide the reserved memory from OS. The same region is reserved for efi_loader. Signed-off-by: York Sun <york.sun@nxp.com>

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is not completed. Finish this work by the tool. During this move, let's rename it to CONFIG_MTD_NOR_FLASH. Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH" than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will make the code more readable. Besides, negative meaning symbols do not fit in obj-$(CONFIG_...) style Makefiles. This commit was created as follows: [1] Edit "default n" to "default y" in the config entry in common/Kconfig. [2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH" [3] Rename the instances in defconfigs by the following: find . -path './configs/*_defconfig' | xargs sed -i \ -e '/CONFIG_SYS_NO_FLASH=y/d' \ -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/' [4] Change the conditionals by the following: find . -name '*.[ch]' | xargs sed -i \ -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \ -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \ -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \ -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/' [5] Modify the following manually - Rename the rest of instances - Remove the description from README - Create the new Kconfig entry in drivers/mtd/Kconfig - Remove the old Kconfig entry from common/Kconfig - Remove the garbage comments from include/configs/*.h Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-01-28arm64: spin-table: add more information in Kconfig helpMasahiro Yamada
This feature seems to be sometimes misunderstood. The intention is: [1] Bring the slaves into the U-Boot proper image, not SPL (unless you have a special reason to do otherwise). [2] The operation must be done in a board (SoC) specific manner since how to wake the slaves from the Boot ROM is SoC specific. [3] The slaves must enter U-Boot proper after U-Boot relocates itself because the "cpu-release-addr" property points to the relocated memory area. [2] is already explained in the help. We can make [1] even clearer by mentioning "U-Boot proper" instead of "U-Boot". [3] is missing, so I am adding it to the list. Instead, "before the master CPU jumps to the kernel" is a matter of course, so removed. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor" breaks u-boot commandline working with long commands sending to the board. Since the above patch, you have to setup the fcr register. For board/archs which enable OF_PLATDATA, the new field fcr in struct ns16550_platdata is not filled with a default value ... This leads in not setting up the uarts fifo, which ends in problems, when you send long commands to u-boots commandline. Detected this issue with automated tbot tests on am335x based shc board.
