generic: fu740: add workaround for CIP-1200 errata

2021-07-27T09:59:59+00:00

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

2021-07-11T05:09:42+00:00

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

2021-07-06T08:51:53+00:00

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

2021-04-28T11:55:00+00:00

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

2021-04-28T11:33:31+00:00

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: sbi: Simplify console platform operations

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

lib: utils: Remove fdt_domain_get() function

2020-12-16T04:40:25+00:00

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

platform: generic: Populate domains from FDT

The generic platform should populate domains from FDT using the domain FDT helper routines. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: sbi: Improve system reset platform operations

2020-12-01T11:40:31+00:00

To implement the SBI SRST extension, we need two platform operations for system reset: 1) system_reset_check() - This operation will check whether given reset type and reason are supported by the platform 2) system_reset() - This operation will do the actual platform system reset and it will not return if reset type and reason are supported by the platform This patch updates system reset related code everywhere as-per above.
