svc, each platform should have their own svc wrapper.
Moreover cezanne PSP will drop unused parameters from
update_psp_bios_dir and save_uapp_data so make wrapper around it.

The CBFS stage header is part of the file data (not the header) from
CBFS's point of view, which is problematic for verification: in pre-RAM
environments, there's usually not enough scratch space in CBFS_CACHE to
load the full stage into memory, so it must be directly loaded into its
final destination. However, that destination is decided from reading the
stage header. There's no way we can verify the stage header without
loading the whole file and we can't load the file without trusting the
information in the stage header.
To solve this problem, this patch changes the CBFS stage format to move
the stage header out of the file contents and into a separate CBFS
attribute. Attributes are part of the metadata, so they have already
been verified before the file is loaded.
Since CBFS stages are generally only meant to be used by coreboot itself
and the coreboot build system builds cbfstool and all stages together in
one go, maintaining backwards-compatibility should not be necessary. An
older version of coreboot will build the old version of cbfstool and a
newer version of coreboot will build the new version of cbfstool before
using it to add stages to the final image, thus cbfstool and coreboot's
stage loader should stay in sync. This only causes problems when someone
stashes away a copy of cbfstool somewhere and later uses it to try to
extract stages from a coreboot image built from a different revision...
a debugging use-case that is hopefully rare enough that affected users
can manually deal with finding a matching version of cbfstool.
The SELF (payload) format, on the other hand, is designed to be used for
binaries outside of coreboot that may use independent build systems and
are more likely to be added with a potentially stale copy of cbfstool,
so it would be more problematic to make a similar change for SELFs. It
is not necessary for verification either, since they're usually only
used in post-RAM environments and selfload() already maps SELFs to
CBFS_CACHE before loading them to their final destination anyway (so
they can be hashed at that time).

Since prog_locate() was eliminated, prog_rdev() only ever represents the
loaded program in memory now. Using the rdev API for this is unnecessary
if we know that the "device" is always just memory. This patch changes
it to be represented by a simple pointer and size. Since some code still
really wants this to be an rdev, introduce a prog_chain_rdev() helper to
translate back to that if necessary.

This patch removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.
This patch is the first step of this move, later patches will do the
same for SELFs and other program types.
