2019-12-02common: Move older CPU functions to their own headerSimon Glass
These should be moved to driver model, but in the meantime, move them out of the common header to help reduce its size. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2018-06-19common: Fix cpu nr type which is always unsigned typeMichal Simek
cpu_cmd() is reading cpu number via simple_strtoul() which is always unsigned type. Platform code implementations are not expecting that nr can be negative and there is not checking in the code for that too. This patch is using u32 type for cpu number to make sure that platform code get proper value range. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
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>
2017-08-01armv8: Remove duplicate definition for IH_ARCH_ARM and IH_ARCH_ARM64Alison Wang
The duplicate definitions for IH_ARCH_ARM and IH_ARCH_ARM64 are removed. The definitions in <image.h> are used. According to this modification, the comparison between os arch and cpu arch is done in C programming instead of ASM programming.

2016-11-22armv8: fsl-layerscape: SMP support for loading 32-bit OSAlison Wang
Spin-table method is used for secondary cores to load 32-bit OS. The architecture information will be got through checking FIT image and saved in the os_arch element of spin-table, then the secondary cores will check os_arch and jump to 32-bit OS or 64-bit OS automatically.

2016-11-22armv8/fsl-lsch3: Update code to release secondary coresPriyanka Jain
NXP ARMv8 SoC LS2080A release all secondary cores in one-go. But other new SoCs like LS2088A, LS1088A release secondary cores one by one.

2016-10-06armv8: fsl-layerscape: Fix "cpu status" commandYork Sun
The core position is not continuous for some SoCs. For example, valid cores may present at position 0, 1, 4, 5, 8, 9, etc. Some registers (including boot release register) only count existing cores. Current implementation of cpu_mask() complies with the continuous numbering. However, command "cpu status" queries the spin table with actual core position. Add functions to calculate core position from core number, to correctly calculate offsets. Tested on LS2080ARDB and LS1043ARDB. Signed-off-by: York Sun <york.sun@nxp.com>
2015-11-30armv8: fsl-layerscape: Fix "cpu release" commandYork Sun
When one core is released, other cores may not have valid entry address. Those cores are trapped by "wfe" and wait for further instruction. When their address is set, they need to be kicked off by "sev". Signed-off-by: York Sun <yorksun@freescale.com>

2015-10-29armv8/fsl_lsch3: Change arch to fsl-layerscapeMingkai Hu
There are two LS series processors are built on ARMv8 Layersacpe architecture currently, LS2085A and LS1043A. They are based on ARMv8 core although use different chassis, so create fsl-layerscape to refactor the common code for the LS series processors which also paves the way for adding LS1043A platform.
