intelvbttool: Add support for reading vbt from sysfs
VBT on Intel(R) systems is available via sysfs as /sys/kernel/debug/dri/0/i915_vbt However the size of this file reads as 0 causing intelvbttool to fail. This patch implements incremental reads with realloc for such cases or whenever the file size is not available (e.g. reading from stdin). After this patch is applied, intelvbttool can be used as follows: sudo intelvbttool -f /sys/kernel/debug/dri/0/i915_vbt -d Change-Id: I5d17095a5747550b7115a54a7619b7294a846196 Signed-off-by: Alex Feinman <alexfeinman@hotmail.com> Reviewed-on: https://review.coreboot.org/c/31531 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>
