[U-Boot] [PATCH v3 0/17] sandbox: Generic board support and other improvements

[Simon Glass]

This series adds generic board support to sandbox and switches to use this
always.

With sandbox it was noticed that turning CONFIG_SYS_GENERIC_BOARD off
can cause a build failure if a previous autoconf.mk exists which indicates
that generic board is not supported, so a patch is provided to fix this.

It is useful to convert a pointer into an 'address' in the sandbox RAM
buffer - the opposite of map_sysmem(). This is added in this series and
used in several places.

With sandbox it is easier to read a file from the host than to use the
CONFIG_OF_SEPARATE option, since this option requires knowledge of the
executable image structure which is not really appropriate on the host
system. A new CONFIG_OF_HOSTFILE provides this.

A few related FDT changes are included in this series also.

The -c option is enhanced to support passing entire scripts to sandbox.
This is useful when writing non-trivial test code.

Most of these patches were previously submitted as part of the verified
boot effort. This series collects the independent sandbox-related patches
together to make it easier to review. THe whole series is marked as
version 3 for this reason.

Changes in v3:
- Rebase on master, to take account of generic board
- Add CONFIG_OF_HOSTFILE support to generic board instead of sandbox
- Remove #ifdefs which are not needed now that we have generic global_data

Changes in v2:
- Use gd->arch.ram_buf instead of gd->ram_buf (now that generic board is in)
- Fix typo "os defined" -> "is defined"
- Use gd->arch.ram_buf instead of gd->ram_buf (now that generic board is in)
- Fix checkpatch warnings about split strings
- fdt_valid() sets the FDT pointer to NULL on error, to simplify callers
- Allow the control FDT to be set even if there is currently no control FDT
- Correct bug in setting control FDT
- Fix checkpatch checks about parenthesis alignment
- Rebase to use updated fdt_valid() function
- Fix checkpatch checks about parenthesis alignment
- Revert the whole change including the set_working_fdt_addr() part
- Move sandbox's command list patch from a later series
