2020-04-17mx7ulp: Only enable LDO if it is not already enabledFabio Estevam
LDO mode may be already enabled by the ROM and enabling it again can cause U-Boot to hang. Avoid this problem by only enabling LDO mode if it is initially disabled.

2020-01-20mx7ulp: soc: s_init should only be executed onceJorge Ramirez-Ortiz
On SPL enabled systems, the current s_init code (wdog, clock and ldo init) is executed twice (by SPL and u-boot). This is not necessary and might lead to boot issues (ie, starting PMC1 when it is already running).

2019-10-08i.MX7ULP: Change clock rate calculation for NIC1 BUS and EXTYe Li
On i.MX7ULP B0, there is change in NIC clock dividers architecture. On A0, the NIC1 BUS and EXT dividers were in a chain with NIC1 DIV, but on B0 they are parallel with NIC1 DIV. So now the dividers are independent. This patch modifies the scg_nic_get_rate function according to this change. Signed-off-by: Ye Li <ye.li@nxp.com> Acked-by: Peng Fan <peng.fan@nxp.com>

2019-10-08i.MX7ULP: Workaround APLL PFD2 to 345.6MhzYe Li
The GPU uses APLL PFD2 as its clock parent (483.84Mhz) with divider set to 1. This frequecy is out of ULP A0 spec. The MAX rate for GPU is 350Mhz. So we simply configure the APLL PFD2 to 345.6Mhz (FRAC=28) to workaround the problem. The correct fix should let GPU handle the clock rate in kernel.

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>
2018-04-28arm: move SYS_ARCH_TIMER to KConfigAndre Przywara
SYS_ARCH_TIMER guards the usage of the ARM Generic Timer (aka arch timer) in U-Boot. At the moment it is mandatory for ARMv8 and used by a few ARMv7 boards. Add a proper Kconfig symbol to express this dependency properly, allowing certain board configuration to later disable arch timer in case there are any problems with it.
