2019-06-24add ctype.h headerJoel Kitching
Sometimes coreboot needs to compile external code (e.g. vboot_reference) using its own set of system header files. When these headers don't line up with C Standard Library, it causes problems. Create ctype.h header file. Relocate ctype.h functions from string.h into ctype.h. Update source files which call ctype.h functions accordingly. Note that ctype.h still lacks five functions which are not used in coreboot source: isalnum, isalpha, iscntrl, isgraph, ispunct BUG=b:124141368 TEST=make clean && make test-abuild BRANCH=none Change-Id: I31b5e8af49956ec024a392a73c3c9024b9a9c194 Signed-off-by: Joel Kitching <kitching@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/33525 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
2019-06-21device_tree: Update comment style to C89Julius Werner
This code was copied from depthcharge which uses C99 comment style, but coreboot uses C89 comment style. Update to match coreboot.

2019-06-21fit: Check all compat strings for highest matchJulius Werner
The compat string matching code was mostly copied from depthcharge. One of the few differences is that we now store the list of compat strings we're willing to match in a list rather than an array. Since our lists insert at the front, that means the strings are now ordered lowest to highest (not highest to lowest like in depthcharge). We did rewrite the compat_rank matching code to accomodate for that... however, what we didn't do is remove the break-statement in the loop that matches all compat strings. When we search the lowest priority first, we can't abort the search as soon as we found a match -- we have to keep looking because we might find a higher priority match later. This patch fixes the issue so that my Kevin can actually match for google,kevin-rev5 (and doesn't just jump at the first best google,kevin match).

2019-06-21fit: Add overlay supportJulius Werner
This patch adds support to boot FIT image configurations consisting of a base device tree and one or more overlays. Since extracting the right compatible string from overlay FDTs is problematic, we'll only support this for FIT images that have the compatible string pulled out into the config node.

2019-06-21fit: Add device tree compressionJulius Werner
This patch adds support for compressing individual device trees in the FIT image. In order to make this efficient, we'll have to pull the compatible property out of the FDT and store it directly in the config node of the FIT image, so that we don't have to scan (and therefore decompress) every single FDT on boot. Device tree compression is only supported for FIT images that have this external compatible property. For older images with no compression, we still support fallback to scanning the FDT for the property.

2019-06-21fit: Refactor config node handlingJulius Werner
This patch makes some minor refactoring to the way the FIT parser handles config nodes. A lot of this code was written in the dawn age of depthcharge when its device tree library wasn't as well-stocked yet, so some of it can be rewritten nicer with more high-level primitives. There's no point in storing both the string name and the actual FDT node of a FIT image node separately, since the latter also contains the former, so remove that. Also eliminate code for the case of not having an FDT (which makes no sense), and move some more FDT validity/compat checking into fit_update_compat() (mostly in anticipation of later changes). This patch was adapted from depthcharge's http://crosreview.com/1553456 with a couple of modifications specific to coreboot's custom FIT loading code.

2019-06-04device_tree: Switch allocations to xzalloc()Julius Werner
The FIT code is already using xzalloc() everywhere, and that's the only real consumer of device tree code right now. Chances are if you're trying to unflatten an FDT and it doesn't fit into the heap you're pretty much screwed anyway, so all the OOM handling feels a bit unnecessary (and some functions will just silently fail because they don't have a return value, which is bad). Let's just switch this all to die on failed allocations.

2019-05-23fit: Add "board-skuX" (without -rev) to allowed compatible stringsJulius Werner
In some cases we may have boards that need to differentiate SKUs but don't really want to differentiate revisions (at least for some SKUs). Let's add a compatible string match that includes only the SKU but not the revision so that kernel DTSes don't have to specify every possible revision if they want to match this.
