coreboot/default: Update to 97bc693ab (2024-07-29)
Several patches are now merged upstream and no longer needed in lbmk, such as the HP EliteBook 8560w patch, and related patches. Some patches were changed, for example the Dell Latitude ivb/snb laptops are now variants in coreboot, instead of being individual ports; now they re-use the same base code. This this, the corresponding files under config/submodules have changed, for things like 3rdparty submodules e.g. libgfxinit, and tarballs e.g. crossgcc. This is long overdue, and will enable more boards to be added. This newer revision will be used in the next release, and some follow-up patches will merge these trees into default: * coreboot/haswell * coreboot/dell Signed-off-by: Leah Rowe <leah@libreboot.org>

+Subject: [PATCH 19/39] mb/dell: Add Latitude E5530 (Ivy Bridge)
+
+Mainboard is QXW10/LA-7902P (UMA). I do not physically have this board;
+someone with physical access to one sent me the output of autoport which
+I then modified to produce this port. I was also sent the VBT binary,
+which was obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running
+version A21 of the vendor firmware.
+
+This was originally tested and found to be working as a standalone board
+port in Libreboot, but this variant based port in upstream coreboot has
+not been tested.
+
+This can be internally flashed by sending a command to the EC, which
+causes the EC to pull the FDO pin low and the firmware to skip setting
+up any chipset based write protections [1]. The EC is the SMSC MEC5055,
+which seems to be compatible with the existing MEC5035 code.
