2020-01-17common: Move hang() to the same header as panic()Simon Glass
At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

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 <trini@konsulko.com>
2018-04-06ARM: AM43xx: Add support for RTC only + DDR in self-refresh modeTero Kristo
Kernel stores information to the RTC_SCRATCH0 and RTC_SCRATCH1 registers for wakeup from RTC-only mode with DDR in self-refresh. Parse these registers during SPL boot and jump to the kernel resume vector if the device is waking up from RTC-only modewith DDR in Self-refresh. The RTC scratch register layout used is: SCRATCH0 : bits00-31 : kernel resume address SCRATCH1 : bits00-15 : RTC magic value used to detect valid config SCRATCH1 : bits16-31 : board type information populated by bootloader During the normal boot path the SCRATCH1 : bits16-31 are updated with the eeprom read board type data. In the rtc_only boot path the rtc scratchpad register is read and the board type is determined and correspondingly ddr dpll parameters are set. This is done so as to avoid costly i2c read to eeprom. RTC-only +DRR in self-refresh mode support is currently only enabled for am43xx_evm_rtconly_config. This is not to be used with epos evm builds.

2016-11-21arm: Introduce arch/arm/mach-omap2 for OMAP2 derivative platformsTom Rini
This moves what was in arch/arm/cpu/armv7/omap-common in to arch/arm/mach-omap2 and moves arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2 as subdirectories. All refernces to the former locations are updated to the current locations. For the logic to decide what our outputs are, consolidate the tests into a single config.mk rather than including 4.
