Hi Simon I don't know if this is correct etiquette but at this moment it feels just right to do this: The problem is not confusion it is that the patch set goes in a direction that makes no sense. On Tue, 26 Oct 2021 at 02:24, Simon Glass wrote: > With Ilias' efforts we have dropped OF_PRIOR_ST

Re: [PATCH] hw/arm/virt: Allow additions to the generated device tree

Hi, Thanks Alex to patch me in. I'd like to present another perspective on the motivation as I can't really comment on the actual "how". On real Arm boards, firmware is often assembled into a FIP. That FIP can contain quite a good deal of things, including an NT_FW_CONFIG, NonTrusted_FirmWare_CO

Hi Simon, this seems a great endeavor. I'd like to better understand the scope of it. Is it to be used as part of what could become a U-Boot entry ABI scheme? By that I mean giving some fixed aspects to U-Boot entry while letting boards to have flexibility (say for instance that the first 5 archi

Re: [PATCH v5 00/26] fdt: Make OF_BOARD a boolean option

Hi Simon Position unchanged on this series: adding fake dts for boards that generate their device tree in the dts directory is not good. If you have them in documentation the it is acceptable. Cheers FF Le mar. 26 oct. 2021 à 02:24, Simon Glass a écrit : > With Ilias' efforts we have dropped

Hi Simon The only place I could agree with this file presence is in the documentation directory, not in dts. It creates a mental picture for the reader an entirely bad mind scheme around Qemu and DT. And even in a documentation directory I would place a bug warning: don’t use this with any kerne
