[U-Boot] [PATCH v4 0/9] Allow sandbox to use config_distro_bootcmd

[U-Boot] [PATCH v4 0/9] Allow sandbox to use config_distro_bootcmd

[Sjoerd Simons]

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.


Version 4 is mostly a rebase on u-boot-dm/next as requested by Simon. As this
branch now has networking support one extra patch had to be added to setup
default PXE client architectures for intel.

Changes in v4:
- New patch to setup PXE client arch on intel systems
- Adapt to sandbox networking support

Changes in v3:
- Fill in *start and *end with proper values
- Improve deprecated sb command short line
- Don't document subcommands for sb anymore

Changes in v2:
- Minor comment coding style improvement
- Move into sandbox/lib/bootm.c
- convert to u-boot coding style
- Remove unneeded cast
- Prevent uncessary casts
- Always unmap mapped sysmem
- Consistently use base variable to refer to unmapped memory
- Various coding style fixes

Sjoerd Simons (9):
  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
  config: Add default client arch defines for intel architectures
  sandbox: add config_distro_defaults and config_distro_bootcmd

[U-Boot] [PATCH v4 1/9] sandbox: only do sandboxfs for hostfs interface

[Sjoerd Simons]

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.

[U-Boot] [PATCH v4 5/9] sandbox: Implement host dev [device]

[Sjoerd Simons]

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.

[U-Boot] [PATCH v4 8/9] config: Add default client arch defines for intel architectures

[Sjoerd Simons]

Define default PXE client architecture identifiers for IA32 (0x0 aka
Intel x86PC) and Intel x86-64 (0x9 aka EFI x86-64).

This prepares for usage for config_distro_defaults in the sandbox
architecture

[U-Boot] [PATCH v4 9/9] sandbox: add config_distro_defaults and config_distro_bootcmd

[Sjoerd Simons]

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.

I had the same reaction initially... These are being defined already in the
new include above.

For me this has broken the build of the "env" target.

I get this following error:

In file included from /home/joe/u-boot/tools/env/fw_env.c:117:
/usr/include/search.h:173: error: expected "}" before
"BOOT_TARGET_DEVICES_references_HOST_without_CONFIG_SANDBOX"
make[2]: *** [tools/env/fw_env.o] Error 1
make[1]: *** [env] Error 2
make: *** [sub-make] Error 2

I haven't looked closely at the header you've added. Any quick
thoughts about what's going on?

Thanks,
-Joe

Hrm, the problem seems to be that when running "make env" CONFIG_SANDBOX
isn't defined, so you get the error triggered above.

Essentially that error is trying to tell you - You're trying to build a
config which will cause your boot environment to have commands not
supported by this build..

I haven't dug out what exactly causes this difference in definitions but
it does make me wonder whether we should trigger on something more
conventional like CONFIG_CMD_HOST (similar to e.g. CONFIG_CMD_MMC)
rather then CONFIG_SANDBOX

That sounds reasonable. Also I think it would be good to add a flag to
enable the distro boot feature. At present I always get the bootdelay
message and then an error:

U-Boot 2015.04-00423-g183ad88 (Apr 23 2015 - 09:05:12)

DRAM:  128 MiB
Using default environment

Out:   lcd
Err:   lcd
Net:   Net Initialization Skipped
No ethernet found.
Hit any key to stop autoboot:  0

Not bound to a backing file

I did a similar thing with LCD since it was similarly invasive.

Simon
