* soc: sifive: ccache: Rename SiFive L2 cache to Composable cache.Greentime Hu2022-10-131-237/+0
| | | | | | | | | | | | | | | | | | Since composable cache may be L3 cache if there is a L2 cache, we should use its original name composable cache to prevent confusion. There are some new lines were generated due to adding the compatible "sifive,ccache0" into ID table and indent requirement. The sifive L2 has been renamed to sifive CCACHE, EDAC driver needs to apply the change as well.

* RISC-V: sifive_l2_cache: Update L2 cache driver to support SiFive FU740Yash Shah2021-01-081-3/+24
| | | | | | | | | SiFive FU740 has 4 ECC interrupt sources as compared to 3 in FU540. Update the L2 cache controller driver to support this additional interrupt in case of FU740-C000 chip. Signed-off-by: Yash Shah <yash.shah@sifive.com> Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>

* riscv: Add support to determine no. of L2 cache way enabledYash Shah2020-05-211-0/+38
| | | | | | | | | | | | | | In order to determine the number of L2 cache ways enabled at runtime, implement a private attribute ("number_of_ways_enabled"). Reading this attribute returns the number of enabled L2 cache ways at runtime. Using riscv_set_cacheinfo_ops() hook a custom function, that returns this private attribute, to the generic ops structure which is used by cache_get_priv_group() in cacheinfo framework.

| | | | | | | | | | | | The commit 9209fb51896f ("riscv: move sifive_l2_cache.c to drivers/soc") moves the sifive L2 cache driver to driver/soc. It did not move the header file along with the driver. Therefore this patch moves the header file to driver/soc Signed-off-by: Yash Shah <yash.shah@sifive.com> Reviewed-by: Anup Patel <anup@brainfault.org> [paul.walmsley@sifive.com: updated to fix the include guard] Fixes: 9209fb51896f ("riscv: move sifive_l2_cache.c to drivers/soc") Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>
* riscv: move sifive_l2_cache.c to drivers/socChristoph Hellwig2019-12-201-0/+178
The sifive_l2_cache.c is in no way related to RISC-V architecture memory management. It is a little stub driver working around the fact that the EDAC maintainers prefer their drivers to be structured in a certain way that doesn't fit the SiFive SOCs. Move the file to drivers/soc and add a Kconfig option for it, as well as the whole drivers/soc boilerplate for CONFIG_SOC_SIFIVE.
