platform: Remove dummy system reset functions

2020-12-01T11:38:47Z

Few platforms have dummy system reset functions so let's remove these dummy system reset functions to allow generic code deal with it in the right way. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis Reviewed-by: Atish Patra

platform: kendryte/k210: Add some padding for FDT fixups

2020-10-18T05:04:37Z

The Kendryte K210 platform has built-in DTB and does not provides FW_PAYLOAD_FDT_ADDR. This means the FDT fixups will be done on the built-in DTB in absence of FW_PAYLOAD_FDT_ADDR. This patch adds some padding in built-in DTB for FDT fixups. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

platform: kendryte/k210: fixup FDT

2020-08-20T09:37:52Z

When passing the device tree to the next stage we should apply necessary device tree fix-ups first. These include: * fix up the CPU node in the device tree * fix up the PLIC node in the device tree * fix up the reserved memory node in the device tree Signed-off-by: Heinrich Schuchardt Reviewed-by: Atish Patra

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

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
