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 25/39] mb/dell: Add Latitude E6220 (Sandy Bridge)
+
+Mainboard is codenamed Vida. I do not physically have this system;
+someone with physical access to one sent me the output of autoport which
+I then modified to produce this port. The VBT was obtained using
+intelvbttool while running version A14 (latest available version) of the
+vendor firmware.
+
+Tested and found to boot as part of a libreboot build based on upstream
+coreboot commit b7341da191 with additional patches, though these do not
+appear to affect SNB/IVB. The base E6430 patch was tested against
+coreboot main.
+
+The EC is the SMSC MEC5055, which seems to be compatible with the
+existing MEC5035 code. As with the other Dell systems with this EC, this
+board is assumed to be internally flashable using an EC command that
+tells it to pull the FDO pin low on the next boot, which also tells the
+vendor firmware to disable all write protections to the flash [1].
