lib: utils/reset: Add Andes fdt reset driver support

2022-10-23T04:59:23Z

Add ATCWDT200 as reset device of AE350 platform, this driver requires SMU to program the reset vector registers before triggering WDT software restart signal. dts example: smu@f0100000 { compatible = "andestech,atcsmu"; reg = <0x00000000 0xf0100000 0x00000000 0x00001000>; }; wdt: wdt@f0500000 { compatible = "andestech,atcwdt200"; reg = <0x00000000 0xf0500000 0x00000000 0x00001000>; interrupts = <3 4>; interrupt-parent = <&plic0>; clock-frequency = <15000000>; }; Signed-off-by: Yu Chien Peter Lin Reviewed-by: Leo Yu-Chi Liang Reviewed-by: Anup Patel

lib: utils/fdt: Use kconfig for enabling/disabling

lib: utils/fdt: Require match data to be const

2022-05-30T05:02:35Z

Match data stores hardware attributes which do not change at runtime, so it does not need to be mutable. Make it const. Reviewed-by: Guo Ren Reviewed-by: Xiang W Reviewed-by: Anup Patel Signed-off-by: Samuel Holland

lib: utils/reset: Generate FDT reset driver list at compile-time

2022-05-13T03:56:06Z

Instead of having FDT reset driver list hard-coded in the C source, we generate it using carray.sh at compile-time. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: fix pointer of type 'void *' used in arithmetic

2022-01-21T16:28:12Z

Using "void *" in arithmetic causes errors with strict compiler settings: "error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]" Avoid these by calculating on "char *" where 1-byte data size is assumed.

lib: utils/sys: Extend HTIF library to allow custom base address

2022-01-11T12:47:49Z

Some of RISC-V emulators provide HTIF at fixed base address so for such emulators users have to hard-code HTIF base address in the linker script. To address this problem, we let users optionally provide fixed HTIF base address via platform support (or device tree). Signed-off-by: Anup Patel Reviewed-by: Dong Du Reviewed-by: Atish Patra

lib: utils/reset: separate driver init func
