We do have an official OpenSBI logo which was designed few months ago and was also approved by RISC-V International. Lets add this logo under docs and also use it in the top-level README.md Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

docs: Correct FW_JUMP_FDT_ADDR calculation example

2023-04-07T05:46:05Z

When using `PLATFORM=generic` defaults, the kernel is loaded at `FW_JUMP_ADDR`, and the FDT is loaded at `FW_JUMP_FDT_ADDR. Therefore, the maximum kernel size before `FW_JUMP_FDT_ADDR` must be increased is `$(( FW_JUMP_FDT_ADDR - FW_JUMP_ADDR ))`. The example calculation assumes `rv64`, and is wrong to boot (off by 0x200000). Fix it and update it for the general case. Signed-off-by: Gabriel Somlo Reviewed-by: Andrew Jones Reviewed-by: Xiang W

platform: generic: Add system suspend test

2023-02-27T14:20:51Z

When the system-suspend-test property is present in the domain config node as shown below, implement system suspend with a simple 5 second delay followed by a WFI. This allows testing system suspend when the low-level firmware doesn't support it. / { chosen { opensbi-domains { compatible = "opensbi,domain,config"; system-suspend-test; }; Signed-off-by: Andrew Jones Reviewed-by: Anup Patel

lib: sbi: Add system_suspend_allowed domain property

2023-02-27T14:15:28Z

Only privileged domains should be allowed to suspend the entire system. Give the root domain this property by default and allow other domains to be given the property by specifying it in the DT. Signed-off-by: Andrew Jones Reviewed-by: Anup Patel

docs: domain_support: Update the DT example

2023-02-27T08:20:27Z

commit 3e2f573e707e ("lib: utils: Disallow non-root domains from adding M-mode regions") added access permission check in __fdt_parse_region(). With the existing DT example in the doc OpenSBI won't boot anymore. Let's update the DT example so that it can work out of the box. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

docs: fix typo in fw.md

docs: domain_support: Use capital letter for privilege modes
