[U-Boot] [PATCH v2 0/8] Allow sandbox to use config_distro_bootcmd
Testing whether images will correctly boot with the standard distro bootcmds can be rather time-consuming as it tends to require flashing the images and booting on a device. Ditto for testing changes to config_distro_bootcmd.
Adding support for sandbox to run distro bootcmds makes things a lot more convenient.
Sjoerd Simons (8): sandbox: only do sandboxfs for hostfs interface sandbox: Split bootm code out into lib/bootm sandbox: Add support for bootz sandbox: Renamed sb command to host sandbox: Implement host dev [device] config_distro_bootcmd.h: Add shared block definition for the host interface pxe: Ensure all memory access is to mapped memory sandbox: add config_distro_defaults and config_distro_bootcmd

Only do sandbox filesystem access when using the hostfs device interface, rather then falling back to it in all cases. This prevents confusion situations due to the fallback being taken rather then an unsupported error being raised.

A very good question. I hadn't actually double-checked what these values are used for as things just worked and i got distracted by fixing other bits & pieces.
Looking through the code, these values are only used to add an LMB region directly after the kernel entry load address. As the sandbox architecture doesn't define either arch_lmb_reserve nor board_lmb_reserve these bogus values don't cause any issues (as they don't seem to make the generic lmb code blow-up thatis), but it's definitely not pretty.
I'll fix up that patch a bit to make those values more meaningful later this.

In the future we may want to emulate this with sandbox. Do you think instead of this we should read out the correct values from the image file? It seems odd to use fake values.
In fact I wonder if this should use a common function with ARM, or perhaps part of it should be common?

I wonder if sandbox could somehow exec the loaded image (presumably it'd only support native executables then, not ARM/x86 zImages), or keep a handle to the file the data was loaded from and fdexec() if such an API exists?

Currently bootm on sandbox does everything except execute the image. I'm sure we could do that to with a bit of fiddling.
The function os_jump_to_image() probably does what you want.

The \"host\" device is used\n""with standard IO commands such as fatls or ext2load"+);
Regards, Simon
A common pattern to check if a certain device exists (e.g. in config_distro_bootcmd) is to use: <interface> dev [device]
Implement host dev [device] so this pattern can be used for sandbox host devices.

Make the sandbox setup more generic/examplary by including config_distro_defaults.h and config_distro_bootcmd.h.
Among other things this makes it easy to test whether images will boot though with the standard distro bootcmds by running e.g: u-boot -c 'host bind 0 myimage.img ; boot'
By default there are 2 target host devices to emulate device with multiple storage devices (e.g. internal ("host 0") and external ("host 1") and verify that the prioritization and fallbacks do work correctly.
