arm64: Layerscape: Survive LPI one-way reset workaround

2020-09-24T15:27:32Z

The workaround of LPI one-way reset issue is broken by the series: https://patchwork.ozlabs.org/project/uboot/list/?series=192398 This patch is to add DT node for GIC RD tables and create corresponding reserved-memory node in kernel DT to fix it.

fsl-layerscape: enable dwc3 snooping feature

2020-09-24T15:27:32Z

Configure DWC3’s cache type to ‘cacheable’ for better performance. Actually related register definition and values are SoC specific, which means this setting is only applicable to Layerscape SoC, not generic for all platforms which have integrated DWC3 IP.

ARM: add Kconfig option for PSCI 0.1

2020-08-05T12:18:34Z

We still have some platforms that only implements functionalities in PSCI 0.1 (e.g. Allwinner ARMv7 SoCs). Add a Kconfig option for exporting only PSCI 0.1. The code to export PSCI 0.1 is still available and gets activated by this patch. In addition, default ARCH_SUNXI U-Boot PSCI implementation to export PSCI 0.1, to fix poweroff/reboot regression on Allwinner multi-core ARMv7 SoCs. Signed-off-by: Icenowy Zheng

arch: arm: use dt and UCLASS_SYSCON to get gic lpi details

2020-07-29T14:37:11Z

Use device tree and UCLASS_SYSCON driver to get Generic Interrupt Controller (GIC) lpi address and maximum GIC redistributors count. Also update Kconfig to select REGMAP and SYSCON when GIC_V3_ITS is enabled. Signed-off-by: Rayagonda Kokatanur Reviewed-by: Simon Glass

board: ns3: add api to save boot parameters passed from BL31

2020-07-29T14:13:41Z

Add API to save boot parameters passed from BL31 Use assembly implementation of save_boot_params instead of c function. Because generally ATF does not set up SP_EL2 on exiting. Thus, usage of a C function immediately after exiting with no stack setup done by ATF explicitly, may cause SP_EL2 to be not sane, which in turn causes a crash if this boot was not lucky to get an SP_EL2 in valid range. Replace C implementation with assembly one which does not use stack this early, and let u-boot to set up its stack later.

arm: add support for SoC s5p4418 (cpu) / nanopi2 board

2020-07-29T12:43:40Z

Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - SPL not supported yet --> no spl-dir in arch/arm/cpu/armv7/s5p4418/. Appropriate line in Makefile removed. - cpu.c: '#include ' added. - arch/arm/cpu/armv7/s5p4418/u-boot.lds removed, is not required anylonger. - "obj-$(CONFIG_ARCH_NEXELL) += s5p-common/" added to arch/arm/cpu/armv7/Makefile since s5p-common/pwm.c is used instead of drivers/pwm/pwm-nexell.c. - s5p4418.dtsi: '#include "../../../include/generated/autoconf.h"' removed, is not necessary, error at out-of-tree building. '#ifdef CONFIG_CPU_NXP4330'-blocks (2x) removed. Some minor changes regarding mmc. 'u-boot,dm-pre-reloc' added to dp0 because of added DM_VIDEO support. - board/s5p4418/ renamed to board/friendlyarm/ - All s5p4418-boards except nanopi2 removed because there is no possibility to test the other boards. - Kconfig: Changes to have a structure like mach-bcm283x (RaspberryPi), e.g. "config ..." entries moved from/to other Kconfig. - "CONFIG_" removed from several s5p4418/nanopi2 specific defines because the appropriate values do not need to be configurable. - nanopi2/board.c: All getenv(), getenv_ulong(), setenv() and saveenv() renamed to env_get(), env_get_ulong(), env_set() and env_save(), respectively. MACH_TYPE_S5P4418 is not defined anymore, therefore appropriate code removed (not necessary for DT-kernels). - nanopi2/onewire.c: All crc8() renamed to crc8_ow() because crc8() is already defined in lib/crc8.c (with different parameters). - dts: "nexell,s5pxx18-i2c" used instead of "i2c-gpio", i2c0 and i2c1 added. gmac-, ehci- and dwc2otg-entries removed because the appropriate functionality is not supported yet. New mmc-property "mmcboost" added. s5p4418-pinctrl.dtsi: gmac-entries removed, mmc- and i2c-entries added. - '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where possible (and similar).

pwm: add driver for nexell

2020-07-29T12:43:40Z

Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - Since drivers/pwm/pwm-nexell.c is an adapted version of s5p-common/pwm.c an appropriately changed version of s5p-common/pwm.c is used instead. Therefore arch/arm/mach-s5pc1xx/include/mach/pwm.h copied to arch/arm/mach-nexell/include/mach and s5p-common/Makefile changed appropriately. - '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where possible (and similar).
