We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

/*

|
* A note on the pxe file parser.
|
|
*
|
|
* We're parsing files that use syslinux grammar, which has a few quirks.
|
|
* String literals must be recognized based on context - there is no
|
|
* quoting or escaping support. There's also nothing to explicitly indicate
|
|
* when a label section completes. We deal with that by ending a label
|
|
* section whenever we see a line that doesn't include.
|
|
*
|
|
* As with the syslinux family, this same file format could be reused in the
|
|
* future for non pxe purposes. The only action it takes during parsing that
|
|
* would throw this off is handling of include files. It assumes we're using
|
|
* pxe, and does a tftp download of a file listed as an include file in the
|
|
* middle of the parsing operation. That could be handled by refactoring it to
|
|
* take a 'include file getter' function.
