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

2022-05-13T03:56:35Z

Instead of having FDT ipi 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

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: utils/ipi: Add FDT based ACLINT MSWI IPI driver

2021-06-24T04:09:51Z

We add a new FDT based ACLINT MSWI IPI driver which works for both CLINT device and standalone ACLINT MSWI device. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils: Try other FDT drivers when we see SBI_ENODEV

2021-05-24T10:19:21Z

We should try other FDT drivers when we see SBI_ENODEV returned by cold_init() of FDT driver. Signed-off-by: Anup Patel Reviewed-by: Atish Patra 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: utils/ipi: Initialize all matching ipi DT nodes

2020-05-23T05:06:49Z

We can have multiple matching DT nodes of the same FDT ipi driver so in this case we should call cold_init() for all matching DT nodes instead of just first matching DT node. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Extend fdt_find_match() Implementation

2020-05-23T05:06:33Z

We extend fdt_find_match() implementation by adding node offset parameter which represents the first node to match from. The improved fdt_find_match() can be used to find multiple match nodes. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Add simple FDT ipi framework

2020-05-01T04:28:01Z

We add simple ipi framework which will select and use ipi driver based on details in FDT passed by previous booting stage. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
