lib: sbi: Fix GET_F64_REG inline assembly

2021-06-12T04:23:33+00:00

Current, GET_F64_REG() macro does not generate correct inline assembly for the RV32 systems. This patch provides separate definitions of GET_F64_REG() macro for RV32 and RV64 systems. Signed-off-by: Charles Papon Signed-off-by: Anup Patel

lib: sbi_scratch: remove owner from sbi_scratch_alloc_offset

2021-06-02T11:37:26+00:00

The parameter owner of function sbi_scratch_alloc_offset() is never used. The scratch memory is small. We should not use it for debug information in future. Hence eliminate the parameter. Signed-off-by: Heinrich Schuchardt Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: sbi: Have spinlock checks return bool

2021-05-14T11:35:20+00:00

spin_lock_check already returned bool in the source file but not in the header. With some toolchains that causes an error, as it should. Because it and related functions all essentially return a bool, we can use this opportunity to change them. Signed-off-by: Daniel Schaefer Reviewed-by: Anup Patel

lib: sbi: Simplify HSM platform operations

2021-04-28T12:01:07+00:00

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

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

2021-04-28T11:30:49+00:00

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

2021-04-28T11:28:23+00:00

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: sbi: Remove domains_root_regions() platform callback

2021-04-28T11:26:58+00:00

We now have sbi_domain_root_add_memregion() which allows platform support to add root domain regions at boot-time so let's remove the domains_root_regions() platform callback which was added for this purpose. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis Reviewed-by: Xiang W

lib: utils: reset: Add T-HEAD sample platform reset driver

2021-04-22T09:43:53+00:00

This driver is for T-HEAD test chip, fpga. It could work with all T-HEAD riscv processors: C9xx series. example1: (Using io-regs for reset) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; entry-reg = <0xff 0xff019050>; entry-cnt = <4>; control-reg = <0xff 0xff015004>; control-val = <0x1c>; csr-copy = <0x7f3 0x7c0 0x7c1 0x7c2 0x7c3 0x7c5 0x7cc>; }; example2: (Using csr-regs for reset) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; using-csr-reset; csr-copy = <0x7c0 0x7c1 0x7c2 0x7c3 0x7c5 0x7cc 0x3b0 0x3b1 0x3b2 0x3b3 0x3b4 0x3b5 0x3b6 0x3b7 0x3a0>; }; example3: (Only delegate plic enable to S-mode) reset: reset-sample { compatible = "thead,reset-sample"; plic-delegate = <0xff 0xd81ffffc>; }; After this patch, all T-HEAD c9xx would use platform/generic with fw_dynamic as default: CROSS_COMPILE=riscv64-linux-gnu- PLATFORM=generic FW_PIC=y /usr/bin/make The platform/thead will be deprecated.
