2021-06-08hw/riscv: microchip_pfsoc: Support direct kernel bootBin Meng1-5/+25
At present the Microchip Icicle Kit machine only supports using '-bios' to load the HSS, and does not support '-kernel' for direct kernel booting just like other RISC-V machines do. One has to use U-Boot which is chain-loaded by HSS, to load a kernel for testing. This is not so convenient. Adding '-kernel' support together with the existing '-bios', we follow the following table to select which payload we execute: -bios | -kernel | payload ------+------------+-------- N | N | HSS Y | don't care | HSS N | Y | kernel This ensures backwards compatibility with how we used to expose '-bios' to users. When '-kernel' is used for direct boot, '-dtb' must be present to provide a valid device tree for the board, as we don't generate device tree. When direct kernel boot is used, the OpenSBI fw_dynamic BIOS image is used to boot a payload like U-Boot or OS kernel directly. Documentation is updated to describe the direct kernel boot. Note as of today there is still no PolarFire SoC support in the upstream Linux kernel hence the document does not include instructions for that. It will be updated in the future.

The contents of this patch were initially developed and posted by Han Han[1], however, it appears the original patch was not applied. Since then, the relevant documentation has been moved and adapted to a new format. I've taken most of the original wording and tweaked it according to some of the feedback from the original patch submission. I've also adapted it to restructured text, which is the format the documentation currently uses.

2021-05-14sphinx: adopt kernel readthedoc themeMarc-André Lureau10-59/+194
The default "alabaster" sphinx theme has a couple shortcomings: - the navbar moves along the page - the search bar is not always at the same place - it lacks some contrast and colours The "rtd" theme from readthedocs.org is a popular third party theme used notably by the kernel, with a custom style sheet. I like it better, perhaps others do too. It also simplifies the "Edit on Gitlab" links. Tweak a bit the custom theme to match qemu.org style, use the QEMU logo, and favicon etc. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Bin Meng <bmeng.cn@gmail.com> Message-Id: <20210323115328.4146052-1-marcandre.lureau@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com>
