lib: utils/serial: support 'reg-offset' property

2022-04-17T08:27:48Z

reg-offset property is used for offset to apply to the mapbase from the start of the registers in 8250 UART. In Linux kernel, it has been handled in 8250 UART driver. dt-bindings: /Documentation/devicetree/bindings/serial/8250.yaml Signed-off-by: Zong Li Reviewed-by: Anup Patel

lib: sbi: Simplify ipi platform operations

2021-04-28T11:33:31Z

Instead of having ipi_send() and ipi_clear() callbacks in platform operations, it will be much simpler for ipi driver to directly register these operations as a device to sbi_ipi implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

lib: sbi: Replace args with trap registers in ecall handler

2021-01-07T04:23:14Z

We had added args pointer in ecall handler to ensure that ecall handler only implements functionality and does not deal with SBI calling convention. This also helped us to keep SBI calling convention related code in one place at sbi_ecall_handler(). The Keystone Enclavce project needs access to the trap regsiters in their ecall handler so that they can context switch enclaves in custom SBI calls. To help the Keystone Enclave project, we replace the args pointer in ecall handler parameter with a const pointer to trap registers. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

platform: Remove dummy system reset functions

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
