platform: generic: move fdt_reset_init to final_init

2021-11-08T05:12:05Z

Move the fdt_reset_init() invocation from generic_early_init() to generic_final_init(). This allows to print error messages. Ignore the return value of fdt_reset_init() as we should not stop booting due to failure to initialize reset drivers. Signed-off-by: Heinrich Schuchardt Reviewed-by: Dong Du Reviewed-by: Anup Patel

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

generic: fu740: add workaround for CIP-1200 errata

2021-07-27T09:59:59Z

Instruction TLB can fail to respect a non-global SFENCE thus we need to flush the TLB using SFENCE.VMA x0, x0 See full description of CIP-1200 in Errata_FU740-C000_20210205 from https://www.sifive.com/boards/hifive-unmatched Signed-off-by: David Abdurachmanov Signed-off-by: Heinrich Schuchardt

platform: generic: Add PMU support

2021-07-11T05:09:42Z

Add PMU support for generic platform. Generic platform solely relies on the device tree to parse all pmu related information. If any event is not described in device tree, generic platform will not support it. Reviewed-by: Anup Patel Signed-off-by: Atish Patra

platform: generic: Terminate platform.name with null

2021-07-06T08:51:53Z

fw_platform_init() fills platform.name without considering the ending null character. Fix it. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: sbi: Simplify system reset platform operations

2021-04-28T11:55:00Z

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

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

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: utils: Remove fdt_domain_get() function

2020-12-16T04:40:25Z

The fdt_domain_get() function is now redundant because the fdt_domains_populate() function can explicitly register new domains using the sbi_domain_register() function. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis Reviewed-by: Atish Patra
