the ddr2 fix broke *ddr3* on gm45 thinkpads in testing, depending on memory modules. this was established by removing patches, re-doing configs etc, on a user's X200 (testing gentoo and freebsd). the X200 kept randomly rebooting or having random glitches. the configs themselves (gm45 thinkpads) will also be re-done, because i found minor issues unrelated, but this patch moves dell e6400 to its own tree. the ddr2 fix is no longer present in coreboot/default, only coreboot/dell. i noticed minor differences in gm45 thinkpad configs, when re-doing the configs, versus what are currently in lbmk master; for instance, vbt was not enabled anymore, on thinkpad x200. modifications to these will be done separately.

Subject: [PATCH 20/22] ec/dell/mec5035: Add command to enable/disable radios
|
|
|
|
These were determined by sniffing the LPC bus while toggling the
|
|
hardware wireless switch on the Latitude E6400. To differentiate devices
|
|
options in the vendor BIOS to change which radios the switch controlled
|
|
were used.
