platform: generic: Change FW_JUMP_FDT_ADDR to 128MB offset

2021-08-04T08:05:02+00:00

OpenSBI defaults to place the FDT 32MB after the start of the kernel but this is not sufficient for a kernel with a large builtin initrd rootfs. This patch change FW_JUMP_FDT_ADDR to 128MB after the FW_TEXT_START to support > 32MB kernel image. This is known limitation, see detail in https://github.com/riscv/opensbi/issues/169 Signed-off-by: Ley Foon Tan

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

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: utils: Remove fdt_domain_get() function

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
