2023-02-10Correct SPL use of MIPS_CMSimon Glass
This converts 1 usage of this option to the non-SPL form, since there is no SPL_MIPS_CM defined in Kconfig Signed-off-by: Simon Glass <[email protected]>
2022-07-13mips: add more definitions for asm/cm.hWeijie Gao
This patch add more definitions needed for MT7621 initialization. MT7621 needs to initialize GIC/CPC and other related parts. Reviewed-by: Daniel Schwierzeck <[email protected]> Signed-off-by: Weijie Gao <[email protected]>
2020-07-18mips: cache: Allow using CONFIG_MIPS_L2_CACHE without CONFIG_MIPS_CMStefan Roese
This patch enables the usage of CONFIG_MIPS_L2_CACHE without CONFIG_MIPS_CM, which is what is needed for the newly added Octeon platform. Signed-off-by: Stefan Roese <[email protected]>

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 <[email protected]>
2016-09-21MIPS: Join the coherent domain when a CM is presentPaul Burton
MIPS Linux expects the bootloader to leave the boot CPU a member of the coherent domain when running on a system with a CM, and we will need to do so if we wish to make use of IOCUs to have cache-coherent DMA in U-Boot (and on some systems there is no choice in that matter). When a CM is present, join the coherent domain after completing cache initialisation. Signed-off-by: Paul Burton <[email protected]>
2016-09-21MIPS: L2 cache supportPaul Burton
This patch adds support for initialising & maintaining L2 caches on MIPS systems. The L2 cache configuration may be advertised through either coprocessor 0 or the MIPS Coherence Manager depending upon the system, and support for both is included. If the L2 can be bypassed then we bypass it early in boot & initialise the L1 caches first, such that we can start making use of the L1 instruction cache as early as possible. Otherwise we initialise the L2 first such that the L1s have no opportunity to generate access to the uninitialised L2. Signed-off-by: Paul Burton <[email protected]>
2016-09-21MIPS: Map CM Global Control RegistersPaul Burton
Map the Global Control Registers (GCRs) provided by the MIPS Coherence Manager (CM) in preparation for using some of them in later patches. Signed-off-by: Paul Burton <[email protected]>
