include: sbi_utils: Introduce an helper to get fdt base address

2021-11-02T05:53:16Z

This simply adds an helper to get fdt address which is more explicit than sbi_scratch_thishart_arg1_ptr. Signed-off-by: Alexandre Ghiti Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: sbi: Add timer frequency to struct sbi_timer_device

2021-09-26T14:22:10Z

Generic mdelay() and udelay() functions can be provided by the sbi_timer framework if timer frequency is available in the timer instance provided by the platform support or timer driver. This patch adds timer frequency (timer_freq) member in the struct sbi_timer_device for above purpose. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils/timer: Allow separate base addresses for MTIME and MTIMECMP

2021-08-14T03:32:33Z

We extend the ACLINT library to support separate base addresses for MTIME and MTIMECMP registers. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils/fdt: Change addr and size to uint64_t

2021-08-07T11:56:51Z

The maximum address and size encoded in DT are 64-bit numbers, so we should use uint64_t for 'addr' and 'size' in fdt_get_node_addr_size(). Signed-off-by: Bin Meng Reviewed-by: Anup Patel

platform: Replace CLINT library usage with ACLINT library

2021-06-24T04:09:55Z

The ACLINT devices are backward compatible with SiFive CLINT so we replace all CLINT library usage in various platforms with ACLINT library. As a result of this replacement, the CLINT library is not used by any part of OpenSBI hence we remove it. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

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: Simplify timer platform operations

2021-04-28T11:30:49Z

Instead of having timer_value(), timer_event_start(), and timer_event_stop() callbacks in platform operations, it will be much simpler for timer driver to directly register these operations as device to the sbi_timer implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

lib: sbi: Simplify console platform operations

2021-04-28T11:28:23Z

Instead of having console_putc() and console_getc() callbacks in platform operations, it will be much simpler for console driver to directly register these operations as device to the sbi_console implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis Reviewed-by: Xiang W

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

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
