+# This grabs current base used, and applies patches
+# This is also used to run deblob scripts.
+
+# (the idea is that this script will reproduce the coreboot directory included with this version of libreboot)
+
+# You need the dependencies from ./builddeb to use this script.

+# The deblobbing target (coreboot git revision) for coreboot-libre is
+# the following commit in the coreboot git repository named "master":

+#     lenovo: Make version look like something thinkpad_acpi would accept
+#     
+#     thinkpad_acpi checks that BIOS version matches some pattern.
+#     Report version in this form.
+#     
+#     Not cleaned up as the idea of this patch seems to be met with resistance.
+#     Can make it Thinkpad-specific if the idea is accepted.

+# We do not need to do a "git reset --hard 63acd22dc5366c72a7165138f5030df9523824dc" here
+# because 5324/9 checkout (see below) eventually goes down to dependency 5320/9

+# Use "git log" in coreboot after this is done, to see what was done.
+# Also use "git diff" to see uncommited changes (after the patch was applied by this script)

+# I create empty versions of the files, and add them using "git add"
+# Now I add the content to those files and all other changes, they will show up in a "git diff" which 
+# was used to create the "gitdiff" file used below. This is also required for applying the gitdiff.
+
+# THE ABOVE IS A HACK. "git add -N" I'm told can do the same thing as above, but that older versions of git do not have this.
+
+# The changes below are in a patch at resources/libreboot/patch/gitdiff
+# These were merged manually.
+# Reason for manual merge: cherry pick wouldn't work with this branch. Didn't want to rebase just to scrap it later. Manual was easier.
+# Also, some of the changes were for different code (eg the 3D fix was previously for the old native graphics code, not the new one).
+
+# apply fix for 3D on kernel 3.12+ for X60/T60 on the new native graphics code (5320/9), 
+# based on manually merging 5927/11 and 5932/5 (which fix the 3D on kernel 3.12+ on X60 for the *old* replay code) from review.coreboot.org
+# apply fix for backlight controls for T60 and X60, based on docs/i945_backlight.html
+# apply fix for IR/digitizer on X60/T60 and X60 Tablet (respectively), based on manually merging 5243/17, 5242/17 and 5239/19 from review.coreboot.org
