platform: kendryte/k210: Use new mechanism of builtin DTB

2020-06-05T03:33:02Z

We update kendryte/k210 to use new mechanism of having builtin DTB where we convert k210.dts to C source and further compile-n-link it with libplatsbi.a. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Allow CLINT functions to be used for multiple CLINTs

2020-05-23T05:06:43Z

We extend CLINT cold init function to have a "struct clint_data *" parameter pointing to CLINT details. This allows platforms to use CLINT functions for multiple CLINT instances. When multiple CLINTs are present, the platform can also provide one of the CLINT as reference CLINT for other CLINTs. This will help CLINTs to sync their time value with reference CLINT using a time_delta computed in warm init function. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Allow PLIC functions to be used for multiple PLICs

2020-05-23T05:06:29Z

We extend all PLIC functions to have a "struct plic_data *" parameter pointing to PLIC details. This allows platforms to use these functions for multiple PLIC instances. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Remove redundant parameters from PLIC init functions

2020-05-23T05:06:26Z

The "target_hart" and "hart_count" parameters of PLIC cold and warm init functions are only used for sanity checks and not required in PLIC initialization. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: sbi_platform: Combine reboot and shutdown into one callback

2020-04-27T09:05:29Z

We can achieve shutdown, cold reboot, and warm reboot using just one sbi_platform callback so we combine system_reboot() and system_shutdown() callbacks into one system_reset() callback. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

platform: Clean up include header files

2020-03-18T04:01:39Z

Adjust the order of include header files in alphabetical order in platform codes. Also remove unnecessary inclusions. Signed-off-by: Bin Meng Reviewed-by: Atish Patra

platform: Use one unified per-HART stack size macro for all platforms

2020-03-14T03:44:00Z

As of today all platforms use 8KB of per-HART stack hence there is no need for each platform to define its own macro or use the magic number. Create one macro for all platforms. Platform still can use its own version if needed. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

include: Make sbi_current_hartid() as macro in riscv_asm.h

2020-03-13T06:52:02Z

The sbi_current_hartid() being a regular function is quite expensive because for callers it is a function call instead of a direct CSR read. This patch converts sbi_current_hartid() into a macro in riscv_asm.h. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Remove disabled_hart_mask from sbi_platform

2020-03-11T10:00:12Z

The disabled_hard_mask in sbi_platform is only 64bits wide so we cannot disable a HART with HARTID > 63. To tackle this, we remove disabled_hart_mask and replace it with hart_disabled() platform callback. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Atish Patra

platform: kendryte/k210: Set per-HART stack size to 8KB

2020-03-08T05:43:31Z

All platform except kendryte/k210 use 8KB of per-HART stack hence this patch set per-HART stack size of kendryte/k210 to 8KB for consistency. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
