utils/reset: Remove fdt_reset_thead

2023-11-16T10:55:23Z

In the past, we used fdt_reset_thead to help customers with prototype verification. However, with the emergence of the Big-little SoC system, it can no longer meet the demand. Therefore, we use zero_stage_boot instead of fdt_reset_thead. It cleans up the opensbi code and ends the disputation of reset_sample's dts. This patch removes the fdt_reset_thead component and updates the related doc. Signed-off-by: Guo Ren Signed-off-by: Guo Ren Reviewed-by: Anup Patel

platform: generic: thead: fix stale TLB entries for th1520/sg2042

2023-10-04T13:29:54Z

The TLB entries remain functional all the time once added in T-HEAD th1520 and Sophgo sg2042 (even if the MMU is then disabled afterwards). If there are some stale TLB entries that contains the address of SBI, it will cause unexpected memory access and issue a illegal instruction error. To avoid this, a TLB flush is needed to drop these TLB entries before any memory access in the trap handler. To handle this workaroud, add a custom trap handler with executing TLB flush first in the T-HEAD platform to fix affected socs. Signed-off-by: Inochi Amaoto Reviewed-by: Anup Patel

lib: utils/regmap: Add simple FDT based regmap framework

2023-07-31T08:39:10Z

We add a simple FDT based regmap framework which is built on top of generic regmap library. The phandle of FDT regmap DT node is treated as unique regmap ID. The FDT based regmap drivers will be probed on-demand from fdt_regmap_get_by_phandle() and fdt_regmap_get() called by the regmap client drivers. Signed-off-by: Anup Patel Reviewed-by: Xiang W

lib: utils/regmap: Add generic regmap access library

2023-07-31T08:39:08Z

We add generic regmap access library which is independent of hardware description format (FDT or ACPI). The OpenSBI platform support or regmap drivers can register regmap instances which can be discovered by different regmap clients based on the unique ID of regmap instances.
