2019-03-15armv7: ls102xa: Add workaround for DDR erratum A-008850Alison Wang
Barrier transactions from CCI400 need to be disabled till the DDR is configured, otherwise it may lead to system hang. The patch adds workaround to fix the erratum.

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>

The default setting for USB High Speed Squelch Threshold results in a threshold close to or lower than 100mV. This leads to Receive Compliance test failure for a 100mV threshold. Shift the threshold from ~100mV towards ~130mV by setting SQRXTUNE to 0x0 to pass USB High Speed Receiver Sensitivity Compliance test.

2017-09-11fsl-layerscape: Consolidate registers space defination for CCI-400 busAshish Kumar
CoreLink Cache Coherent Interconnect (CCI) provides full cache coherency between two clusters of multi-core CPUs and I/O coherency for devices and I/O masters. This patch add new config option SYS_FSL_HAS_CCI400 and moves existing register space definaton of CCI-400 bus to fsl_immap to be shared. CONFIG_SYS_CCI400_ADDR is replaced with SYS_CCI400_OFFSET in Kconfig.
